Problem Statement: How does one duplicate a workspace in Aspen Basic Engineering when using MS Access as the relational database? | Solution: Follow the steps outlined below to duplicate a work space. Please note that this procedure should be followed only if you are using MS Access as the relational Database:
1. Using Administration tool, create a new Work space (e.g. AZ151_copy). Leave all the defaults.
2. Close the Zyqad Administrator application.
3. Go to the workspace folder and open the workspace that you want to duplicate (e.g. C:/AspenZyqadServer/Aspen Zyqad 15.1/Workspaces/AZ151) .
4. Copy all existing files in the folder (specifically the files workspace.mdb, privilegies.xml, workspace.cfg, workspace.udl).
5. Go to the workspace folder of the duplicate workspace that was just created (e.g. c:/AspenZyqadServer/Aspen Zyqad 15.1/Workspaces/AZ151_copy)
6. Paste and replace the copied files.
Key words

Problem Statement: How do I clear a workspace from recent workspace history list? | Solution: When you open Aspen Basic Engineering the “Open Aspen Basic Engineering Workspace� window will appear, in the “Recent Workspaces� tab you will see all the workspaces that have been recently used to perform projects, sometimes you will have many workspaces loaded that could cause confusion to the users of the server.
Â
To avoid that situation, you can remove the workspaces that you don’t longer use. To achieve this you will have to click on the workspace name inside Recent Workspaces tab using the right button of your mouse.
That will reveal a menu where you can choose “Remove� and the workspace will be cleared from that list, as shown below.

Problem Statement: The widths of some columns in AllVariables table are too large. How can I reset these settings? | Solution: You can change the size of columns by pointing with mouse at the separation line between two columns, then hold down the left mouse button to resize.
In some cases, the columns are too wide or not visible, and the operation describe above is not convenient or impossible. It is possible to reset the setting. This information is stored in the registry. You can fix this problem with regedit:
Start menu, run Regedit
go to HKEY_CURRENT_USER\Software\AspenTech\QuickTable\11.1\
delete the key AttributeColWidths
This resets the widths of the columns and hopefully should resolve the issue.

Problem Statement: How to create Manual SQL workspace? | Solution: First step for creating Manual SQL workspace is to create SQL Database on SQL Server. For this example let us assume you have created database with a name ABE-test on SQL server and you should also make sure you create user account which has read, write and create access to this particular database. Let us assume your user account name is ABE for this example.
- Next step is to open Administration Tool
- Click on Action | New Workspace , click Next
- Provide the name of new workspace (i.e. Test1), select a data server, select library set (from drop down box) and select database type (from drop down box) as shown in screenshot below.
- Click Next and select ?Create Manual Workspace? option and provide the SQL server host name, Database name, username and password as shown in the screenshot below.
- In below screenshot,
SQl server name is : SQLServer1
SQL Server Instance name is: SQLEXPRESS (in your case this may be different or this may not exist at all)
Database name is: ABE-test
User name is: ABE (this username should have read, write, create access in your SQL database)
Password is : This should be the same that you provided while creating ABE user ID on SQL server.
-Click Next
-Click Finish

Problem Statement: Do the Aspen Zyqad workspaces need to be setup under the default location (c:\AspenZyqadServer\AspenZyqad[internal version number]\Workspaces) or is there any way to specify a different directory location for the Aspen Zyqad workspaces? | Solution: The broker.ini file (which is located in the dataservices\bin directory in the Aspen Zyqad install directory along with the AZ[internal version number]broker.exe file) defines 2 parameters: WorkspacesFolder and LibrariesFolder. The paths here can be relative or absolute, so the user can set the workspaces to be at any user specified location by defining the WorkspacesFolder parameter in the ini file. The program is going to expect to find Workspaces.lst in the specified directory.
The default location for the dataservices\bin directory is in the c:\program files\aspentech\aspen zyqad [external version number] folder.
Notes: The [internal version number] here refers to numbers like 14.1, 15.1 etc. The [external version number] here refers to numbers like 2004.2, 2006, 2006.5 etc. For example, for V2006, the internal version number will be 14.1 and the external version number will be 2006. The information provided above applies to other versions as well.

Problem Statement: Why do I see too many folders under the workpspace folder but Aspen Basic Engineering administration tool only shows few of them as a workspace? | Solution: There can be numbers of reasons for this, most common reasons are mentioned below.
1. Check if your name is added in ZyqadAdministrators user group.
To see all workspaces you should be a member of ZyqadAdministrators group.
Also, check Workspaces.lst file located under Workspaces folder. You can open this with any text editor and see list of active workspaces. i.e. WORKSPACE AZ162 AZ162 Active indicates AZ162 workspace is active. You should see all active workspaces in Aspen Basic Engineering administration tool.
2. Unsuccessful workspace creates folder
Whenever you try to create a new Workspace and due to any reason if that process is unsuccessful, the folder with workspace name will be created under Workspaces folder.
3. Delete action from administration tool leaves folder structure intact on server
When you delete any workspace from Aspen Basic Engineering Administration tool, it does not delete the folder located under Workspaces folder.

Problem Statement: How to populate the PFDNumber attribute when inserting an equipment on a drawing | Solution: This can be done with a Demon. The attached example use the Representations attribute to trigger the demon which will specify the PFDNumber on the equipment object. In order to install the demon, you first need to copy the file in the KBS directory of your library. And in the library config file (e.g. StandardLibrarySet.cfg), you need to add the filename (WPSetPFDExampleazkbs) in the list of KBScript.

Problem Statement: Why is test api slow when running CIMIO for foxboro FOXAPI? Is my DMCplus controller IO affected by this? | Solution: On a Foxboro system with Foxboro FoxAPI 4.2 or later, the internal data sets management were revamped to be more efficient when it is opened, but it would take a lot longer to open a new data set. The Test Api is a new CIM-IO clien,t so the new data set is opened every time the read request is issued. As a result, the request may time out if the time out limit is set too low. It is a normal behavior for this interface.
This is true for a DMCplus controller, the first time a controller is loaded and run. It would take a long time, but once the data set is opened, subsequence reads from the same controller would take a lot less time. A more realistic test would be set up a data collection with a large number of tags. Run it for awhile and see whether the communication is timing out on a regular intervals.
The slow response to TEST API is not indictive of the performances of DMCplus controller CIMIO client response.

Problem Statement: How does Aspen DMCplus Collect handle daylight savings time (DST) changes? | Solution: Daylight Savings Time changes happen twice a year. Most of the AspenTech software (DMCplus, IP.21) handle the time change by using the GMT instead of the system clock. DMCplus Collect handles time changes differently. The data collection will record the beginning time and the number of samples after each scan. Thus the time changes based on DST will not affect data collection. The extraction would not overwrite any data due to DST changes.
However, the data after the time change will have 'incorrect' time stamp when examined in DMCplus model. It is strictly cosmetic because DMCplus Model does not use time stamp in its calculations. If the 'correct' time stamps are desired, stop the data collection before the time change, wait one hour and start the data collection again. Waiting for one hour before starting the collection will ensure that the data is not overwritten.

Problem Statement: What does the message 11107 ET waiting for LP/QP | Solution: mean? and what causes this message to be displayed?
Solution
The message ET waiting for LP/QPSolution indicates that the ETs specified for the controller are not valid (Status = GOOD) and the controller algorithm is waiting for the SS targets from its internal LP/QP algorithm to use as the desired condition to move the plant to. The above message commonly shows up in two conditions-
1. When the DMCplus controller sheds all RTO type ETs - In such a case, the controller revets to standard economic calculations and uses the SS targets supplied by the LP/QP algorithm.
2. On the first execution cycle of a DMCplus controller with tracking enabled for IRV type ETs- In case ETs are enabled along with the ET tracking, the controller delays using the ETs for one control cycle as the ET Statuses are at BAD and not GOOD in the first controller execution cycle. During the first cycle DMCplus sets the ET value equal to the Steady StateSolution obtained from the LP/QPSolution to start the controller execution. The controller switches to the defined ET values during the second execution once all the ET Statuses go to GOOD. This is the reason for the “ET waiting for LP\QPSolution� on the first step. If the ET statuses do not go to GOOD during the second execution, the controller will use the SSSolutions to perform the calculations as ET Tracking is enabled.
To stop receiving this error/warning message every time the DMCplus controller is loaded, open the ccf file in Build and set the ETCTRK parameter for all of the variables to 0 (ET Tracking OFF). This can also be done using Simulate. Open the CCF file in DMCplus Simulate and set the value of column ET Track for both the MVs and CVs to 0.

Problem Statement: You have standard Units of Measure and Formats for fields on datasheets that you want to easily apply | Solution: To do so, you need to:
1. Investigate how Formats and Units are stored for a datasheet
2. Create a datasheet template with correct unit and formats to copy from
3. Write a method that will copy the information from the template to another datasheet
The method described above is attached. Download the .azkbs file, compile to create .azkbx file and load into workspace for use.
Note: Please close and reopen the datasheet so the format changes will be reflected.

Problem Statement: Why does the CMOV does not reach the MAXMOV?
Maximum Move (MAXMOV) is defined as the largest change (in engineering units) the controller is allowed to make in the manipulated variable set point in one cycle. However the Manipulated variable current move (CMOV) does not reach this value. | Solution: Review the IPSKIP parameter in the configure section of your CCF. When IPSKIP >1, Move Normalization is used. The effect of using move normalization is as follows:
- The controller a??thinksa?? it cana??t move again for IPSKIP intervals, but actually it will have the opportunity to make a new move at the next control interval
- The moves calculated by the controller are spread evenly (a??normalizeda??) over the prediction intervals using the following equation:
ActualMove = CalculatedMove / IPSKIP
This also applies to the MAXMOV. That is why CMOV does not clamp to MAXMOV but to 1/IPSKIP of MAXMOV.
You can use either of these two options:
1. In your CCF go to tools / options / Engine tab and use Custom Moves. The default number is 30 but you can change this value and increase controller reSolution. This will increase the CPU load so you should make this this change carefully if CPU resources are limited. With higher control reSolution verify that the ratio of model coefficients to controller coefficients (IPSKIP) is one, therefore move normalization wona??t be used.
2. Use a different value for the maximum move MAXMOV_NEW = MAXMOV*IPSKIP

Problem Statement: dpp files generated in DMCplus Model Vx.x cannot be opened using an older Vx.x. | Solution: Forward compatibility means that a .dpp file generated from an newer version of DMCplus Model can be loaded into a older version.
Even when this was possible in older versions (e.g. between V2006.5 and V7.3); this was not a by-design feature. Forward compatibility is not available for newer dpp files (e.g. V7.3 and V8.4).
A workaround for this issue is to export vectors (data) and models from the newer dpp file, then reimport them on the older version.

Problem Statement: How to get Aspen DMCplus context info using tag names instead of index numbers. | Solution: The information from the DMCplus Context can be read using a cimio client. The default tag names convention for scanning the Context server data is
M CtlName Parameter VALUE index
For Example:
To get the ONSTS on a COL5X3 controller, the syntax is
M COL5X3 ONSTS VALUE
To get the VINDSP for a 3rd MV on the COL5X3 controller, the syntax is
M COL5X3 VINDSP VALUE 3
However, there is an alternate way of getting the same information on variables (MVs,FFs,and DEPs) in a controller using the tag name instead of the index.
M Cltrname variablename|paramname
For example:
If the 3rd MV on the COL5X3 is FC2001, the syntax to get the VINDSP is
M COL5X3 FC2001|VINDSP
Because the tag name is used instead of the index, any duplication of tag names will result in an unpredictable value being returned. Thus the recommendation is to have unique tag names among the variables in each controller.

Problem Statement: APC applications unable to get valid SLM license key from license server
One reason for this is the possibility that the client has used and environment variable LSHOST to define the license server hosts, instead of the SLM Configuration Wizard. When the LSHOST variable is configured, it will over-ride any SLM server configurations made with the SLM Configuration wizard. | Solution: If the LSHOST variable has been established on a machine, you can add your SLM license server to the list, either by machine name or by using the ip address. Be sure to close the my computer windows, before attempting to get a license key, so that the addition of the new server is recognized.
You will find the environment variables by highlighting my computer, on the desktop, right clicking and going to properties, then advanced and then to environment variables.
If the LSHOST does not appear, then you will want to continue by confirming the installation of the proper license file on the appropriate license server with it's designated locking mechanism. You will also want to configure the license server with the SLM configuration wizard.

Problem Statement: What is shadow price of manipulated variable and dependent variable? | Solution: SHPMAN and SHPDEP represent the improvement, in economic units, in the objective function that is achievable if the constraint limit on which the steady stateSolution is riding can be relaxed by one unit (engineering units of the MV or CV here). These costs are always zero for constraints that are not limiting in the steady state optimization.
Furthermore, the costs represent the improvement from a one-unit relaxation of a limiting constraint at the new optimal steady stateSolution that is calculated by the steady state optimization on each cycle. As such, it is the value achievable from the next unit of either the MV or the CV.
Also keep in mind that SHPMAN is not necessarily equal to CST because of the interacting constraints present in a typical DMCplus controller.
In summary, the values of SHPDEP and SHPMAN represent cost per engineering unit of the constraining CV or MV at the new steady stateSolution.

Problem Statement: How can I change the dimension units on the active data sheet? | Solution: If you want to change units on the active data sheet, there are three options that can be pursued:
Option 1
Change the unit displayed in a particular field
Click on the unit
Select the unit of interest from the list
Please note that Zyqad will perform unit conversions. If you have entered 37C as the temperature and then change the display unit to F, the temperature will be automatically converted to 99F. So it is good idea to change the unit of measure first, then enter the number.
Option 2
Change the unit of quantity on the active data sheet
Open the Data sheet | Dimension Unit menu
Select the quantity of interest
Change its unit
Option 3
Change the dimension set on active data sheet
Open the Data sheet | Dimension Set menu
Select the Unit Set of interest
Please note that above mentioned options will only change the units for the active data sheet. If you want to change units globally, seeSolution ID 104158.

Problem Statement: This knowledge base article provides an explanation of pcsget errors and their effect on the Aspen DMCplus application. | Solution: PCSGET errors are cimio read errors. These can be found in the valid.err log, and can be further investigated by looking at the cimio_msg.log file from the destination machine, or the machine running the interface software.
In 2004 and later, a PCSGET error causes all the tags being read in that particular list to be set BAD. Earlier versions just took the controller offline when a PCSGET error occurred.
If one of the tags being marked BAD is a critical variable, the controller will go offline. If it takes more than one list to get all the tags and the list with the PCSGET error does not have a critical variable in it and you get enough good reads to satisfy the minimum number of good MVs and CVs, the controller might actually stay online after a PCSGET error.
Missed Cycles means that the controller did not run on time and had to wait for the next scheduled time to run. A PCSGET error could conceivably cause that to happen if the list times out, the controller continues to run but takes more than one control cycle to solve. But that is related to wall clock time, not PCSGET errors.
At one time we had a CQ in the system to create an RFAILM value corresponding to the WFAILM value used for controlling the action taken when you get a PCSPUT error. This was rejected because it would pose a safety issue.

Problem Statement: When compiling datasheets using the Datasheet Definer, is it possible to include Excel graphs when compiling the datasheet? | Solution: Unfortunately, it is not possible to add graphs when working with the Datasheet Definer and then compile the datasheet. If the user tries this option, when the datasheet is open using the XLDSE (Excel DataSheet Editor), no data will be displayed in the graph as Excel is not able to read real values that are defined in ABE fields.
If the user wants to make graphs with the data displayed in the datasheet, the user should create the graph using the XLDSE tools, but not before the compilation process.

Problem Statement: How to export workspace data to excel using VBA macro | Solution: The attached excel file includes an example of macro which can be used to export data to excel. This example creates an equipment list based on a class view where the list of attributes has been defined.
1. The first step is to implement the class view EquipmentListExcelReport in the data model. If you haven't modified the standard model supplied by AspenTech, you can copy the files StandardModel.azcs and StandardModel.azcl in the folder:
For 2006.5: C:\AspenZyqadServer\AspenZyqad15.1\WorkspaceLibraries\DataModel\StandardModel
For v7: C:\AspenZyqadServer\Basic Engineering16.X\WorkspaceLibraries\DataModel\StandardModel
If you want to implement the class view in a custom model, you can load the file ExcelMacro.azci as an Include Library. This is done by selecting the folder Included Libraries in the Class Library Editor, right click and select the azci file which has been previously copied in the custom data model folder.
2. In order to generate the equipment list, you need first to download the excel file according to the version you are using. You need to connect on a workspace by using the Open Workspace button on the intro tab. After the connection has been established, you can click on the Create Equipment List button. This will create a new tab with the list of equipment and some attributes.
Please Note: As you can see on the list, some attributes are valid only for certain type of equipment. For instance, the attribute TemaType will only be populated for equipment of class ShellAndTubeHeatExchanger. This can be done by linking the class view with multiple composite views. If you select the classview EquipmentListExcelReport in the CLE application, right-click on an attribute and select Show links for alternate class, you will see that this class view is linked to three composite views related to the classes ProcessPlantEquipment, CentrifugalPump and ShellAndTubeHeatExchanger.
You can see the code by opening the Visual Basic editor (Alt+F11). The transfer of data is done by using the function ReadViewEx from the AZCSMappingSvcs dll. This function needs the following arguments:
pWorkspace (object accessed through the AZClientTools dll)
strApplication (defined in the application properties of the class view)
strUsage (defined in the application properties of the class view)
strApplicationClass (defined in the application properties of the class view)
iOID (OID parameter of the object you want to transfer the data)
iCaseID (case id, 1 is normally the Design case)
strXMLErrors(string which will contain the error message)
[Attributes] (Optional argument used when a limited number of attributes needs to be transferred instead of all the attributes from the class view)

Problem Statement: When trying to put a variable into service, you get an error message:
Cannot go from BAD to USEPRD | Solution: The mechanism involving useprd (use prediction) is used for an intermittent signal, such as an analyzer or something of that nature.
Normally, predictions for each variable are calculated for a cycle, and then next cycle, after reading the actual values, predictions are once again calculated, but from the actual value for that cycle, and the process continues indefinitely. This is how the controller keeps track of where it has been, on a per variable basis, and where it is going, on a per variable basis, based on the constraints and targets.
In the case of an intermittent variable, it doesn't get a new actual value, so it can't re-adjust it's predictions for each cycle. If it is going to calculate predictions for the intermittent variable, the only thing it has to predict from is the value that was predicted the last cycle, so any error in the prediction will, of course, be compounded. Still this will serve for a fairly brief period of time, which is specified by the entry MXUSPR. (See the entry dictionary in DMCplus help)
In the event that the value has become bad either because it has not been refreshed with an actual value from the analyzer for a longer period than specified by MXUSPR or perhaps there was something wrong with the source, and the value was marked as bad when it was received, then the message is essentially saying that the value is too old and the accuracy is too uncertain to use it for predicting the value of that analyzer.
That variable can only be put in service after it has received an actual good value from the analyzer so it can start its predictions from a known good value.

Problem Statement: This document list the issues which has been noticed when testing Aspen Zyqad 11.1 SP1 on Windows XP. | Solution: 11.1 Windows XP Installation
During the Windows XP installation of Aspen Zyqad 11.1 you may see a Windows File Protection dialog displayed which asks you to insert your Windows XP CD-ROM. This is because at 11.1 Aspen Zyqad tries to install the system file ctl3d32.dll. The version of this file is the same as the version released with Windows XP and so you can safely choose Cancel or Close on the dialog. The installation will then continue normally.
Graphic Definer
When the Graphic Definer is launched on Windows XP by a user who is not a member of the Administrators or Power Users group, the splash screen will display momentarily. The application will then terminate. To work round this problem, run the Graphic Definer once as user who is a member of the Administrators or Power Users group. Subsequent use by all other users should then behave as normal.

Problem Statement: Under 'Attribute' privilege, three privileges are listed,
What is the meaning of these privileges? | Solution: LockAttribute: This privilege is required to be able to lock an attribute.
In datasheet editor, If you right-click on an attribute in datasheet editor and pick 'status', you will find an option 'Locked'. When you check this box, this will lock the attribute and other users will not be able to modify it. The privilege 'lock attribute' in administration tool grants/denies a user this right
OverrideAttributeLock: Only if the user has 'overrrideAttributeLock' privilege, then he/she can override a Lock that has been placed on an attribute. In administrator tool, you can grant or deny this privilege.
SecureAttribute: The privilege required to secure an attribute and to view a secured attribute
In the same window, i.e.status window, there is another box 'secure'. This means you can secure the attribute. If an attribute has secured flag, it will not be visible to other users. To other users, it will be displayed empty. 'SecureAttribute' privilege in administration tool controls on granting and denying this privilege to users.

Problem Statement: Why I am getting error message Error while checking out license (feature name) returned error: SLM Configuration Information in Production Control Web Server and error 18.
For example, while trying to load Aspen DMCplus controller online, it displays this same error message in valid.err, while Aspen DMCplus model, build and simulate works fine without any license errors. | Solution: There could be multiple reasons for Error 18, while checking out license for any Aspen product features one of which being incorrect bucket configuration. Other reasons could be:
- License file not placed at the correct location
- Key expired at a past date
- SLM communication ports not open
- All available tokens consumed
In thisSolution, incorrect bucket configuration for the SLM_APC_MV feature has been discussed.
At times, some of the license features in a particular license is available in different bucket other than the default bucket. The bucket for any feature in a specific license could be found out using SLM License Profiler-> Load information-> View licenses.
A bucket is a container inside an SLM license file of type Network that allows grouping license keys.The first bucket is indicated as the Default bucket.
Now, if a license feature (SLM_APC_MV) is available in a bucket other that the default bucket, which is bucket #3 as per above example and SLM Configuration Wizard is not configured to pick up license from that bucket, it will show up license error when we will try to access the Aspen DMC plus online applications.
The error message in the valid.err file will be - Error while checking out license (SLM_APC_MV) returned error: SLM Configuration Information.
Also, Error 18- License for the specific product couldn't be found, will be seen in Aspen Production Control Web Server screen.
TheSolution to this problem is to configure the SLM configuration wizard, so that it can pick up license from all the available buckets at runtime. To configure the this setting, go to Start-> All programs-> AspenTech-> Common utilities-> SLM configuration wizard and select YES option for “will you be connecting to network server”.
On the “Servers” page, make sure that your license server is available. Then check the option “Search Configured Servers for all available Buckets at run time” as shown below and proceed next till finish. This will configure SLM configuration wizard to pick up license from all buckets.
When we select “Search Configured Servers for all available Buckets at run time”, it will bring up all the available buckets for the specific license.

Problem Statement: What are the things that I can check when I get the below error message on clicking part definition in graphic definer? | Solution: Mainly, there are two reasons of occurrence of this error message:
1) Dll file is corrupted
In RAD applications each menu item is implemented in a separate DLL. The Part Definition command is handled by the 'AZ161GDPartDefinition.dll' ( v 7.0), which by default is located at C:\Program Files\AspenteTech\Aspen Basic Engineering v 7.0\UserServices\bin
Either the registry key for this command has corrupted or the DLL itself got corrupted. There can be following way outs,
- Re-register this dll.
- If that doesn't help, you can replace this dll file with a good dll file.
- Final option is, re install zyqad.
2) Intergraph version is not compatible.
Both the application use the Intergraph graphics tool, RAD. If there is a different versions of RAD in Aspen Basic Engineering than Smartplant, that can be the reason of error message. Make sure versions of both applications are compatible and can exist on same machine.

Problem Statement: After installing Aspen Manufacturing Suite V7.3, could not locate Production Control Web Server in AspenTech directory through Start-> Programs-> Aspen Manufacturing Suite.
Also, multiple services like Aspen ACO utility server, Aspen web provider data, AFW security client, ACO view data provider etc. were not available under services list. | Solution: Any Aspen product installation always requires selection of Computer Configuration Type- Server Install or Standard Install, after the step of agreeing to the license agreement.
For Advanced Process Control installation, this configuration type has to be selected carefully as APC has both server & desktop components.
o Standard Install should be selected if only APC Builder (desktop) product will be installed.
o Server Install should be selected if an APC Online, APC Web Server, or APC Performance Monitor software products will be installed, along with APC Builder (desktop).
In case of a scenario, where Online & Web server components are required for process, and by mistake Standard Install is selected instead of Server Install during installation, then the components like Production Control Web Server, Aspen ACO utility server etc. will not be available.
This is because, only server install helps to install server components.

Problem Statement: How are External Targets different from a steady state controlled variable, in Aspen DMCplus? | Solution: One of the operations of Aspen DMC controllers is to find out an optimum (most profitable) point within a range of operation, based on the process & economic inputs. The optimum values for MVs and CVs that are calculated as a result of the economic optimization of the process (by the DMC controller) are known as the Steady State Targets of these variables.
External Targets, on the other hand, are desired operating values for MVs and CVs that the controller cannot determine based on the limited information that is supplied to it. External Targets could either be Set Points entered by operator (example Temperature or Flow Biases in a furnace should be held at 0 to minimize differential coking within the tubes) or could be optimal set points calculated by a supervisory controller or optimizer (Real Time Optimization on plant-wide scale).

Problem Statement: What happens to the MVs in a test group that is put in CONTROL mode while the rest of the controller is in CALIBRATE or SMARTSTEP mode? | Solution: When a DMCplus controller is put in CALIBRATE or SMARTSTEP and one of the test groups is put in CONTROL mode, the MVs in the test group are essentially in SUSPEND mode (MINMOVE) until the process drifts outside of the limits.
In CALIBRATE mode, the controller engine will move the MVs to minimize the LP cost function if the process drifts into the optimization zone defined based on the calibration ratio and brings the process back into the calibrate zone of operation. When the process gets back into the calibrate zone, the MVs will stop moving and the status for the MVs become MINMOVE. The engine will also move the MVs if the process drifts outside the operating limits and bring the process back into the calibrate zone.
In SMARTSTEP mode, the MVs in the test group that is in CONTROL are not optimized, they remain in SUSPEND (MINMOVE) until the process drifts outside the limits. When this happens, the control engine moves the MVs to bring the process back within limits and then stops moving the MVs.
Thus the CONTROL mode of a DMCPlus controller in SMARTSTEP and CALIBRATE does not provide the same functionally as a DMCplus controller in CONTROL mode.

Problem Statement: Are RDWRT, LWRITE, PWRITE, WRITE written back by DMCplus every controller cycle? | Solution: The DMCplus controller does not write to all of the WRITE/RDWRT/PWRITE etc. parameters every cycle. Validation checks are used to determine which parameters get written during a given cycle. Only parameters in which the controller has calculated a modified value and in which the controller would need to output the parameter is the value written out. The ONREQ is one of these parameters. Only if the validation logic deems it necessary to write out the ONREQ parameter would the controller write this parameter. Any custom calculation should include its own validation to ensure proper operation if it is going to write to this parameter. There is a full discussion of the ONREQ parameter in the entry dictionary which includes a discussion of when the controller will write this parameter. In general, it is recommend not writing an AWRITE variable to this parameter.

Solution
CIO110519D -Solution 132145 was not installed.
This patch has to be installed as theSolution 133411 says as follows.A
Note: This patch installs a version of the cimio.dll that will be incompatible with the cimio installed with Advanced Control Products V7.1.A After this update is applied, also applyASolution 132145 - V7.1 ER CIO110519D to correct this problem.
When the DMCplus put error happened WNT Error = 10054 is logged in the CIMIO_MSG.LOG.
It usually means the network hardware failure. This error message is misleading, as the real cause of the problem was a missing patch.A

Problem Statement: How can I switch the precedent letter that is assigned to an equipment in Aspen Basic Engineering(ABE)? | Solution: In the class of every equipment, there is a NamePrecedent attribute which has a default value e.g. H is for Heat Exchanger, P is for Pump. You can modify its default value or, if necessary, you can add NamePrecedent attribute at class level. I will take an example of agitator for demonstration. When an agitator is created, its name starts with M, you can switch this to any desired letter by following the procedure:
Open the *azcl file in CLE and open class agitator.
Arrange the attributes in alphabetical order to look for NamePrecedent.
Right click on its properties.
The default value is M-, change it to e.g A-.
Check for errors and compile the class store.
After you will reload the workspace, create a new agitator, its name will be A -***.
Same way you can change the Prefix for other equipments. If Nameprecedent attribute is grayed out for a class and you cannot change it, then you can add a new attribute in the class with same name and change its default value, it will override the original one.
Keywords: Prefix, precedent.

Problem Statement: In some cases when connecting via DCOM to a freshly installed server under Windows 2012 R2, the following error appears:
Error Message:
<AZError Desc=Could not connect to the Business server 'server_name.net'.
Change Business server name or update transport connection options,
by clicking Advanced button in the main dialog. Src=ProjectBrowserDialog::UpdateTreeView Activity=Connecting to Business Server HR=E_ACCESSDENIED File=ProjectBrowserDialog.cpp Line=232 />

<AZError Desc=Zugriff verweigert HR=E_ACCESSDENIED />
When changing manually to TCP/IP and Port 2225 the connection to the server is possible.
Connections to an older server running under Windows 2008R2 are still possible with DCOM | Solution: In order to avoid this issue which is related to the file access rights, it is suggested to keep the ABE installation folder readable to all members of the local ZyqadUsers group, especially the folder AspenTech\Basic Engineering V8.4\DataServices\
If the user has locked it down, leaving it only open for members of ZyqadAdministrators, assuming that only the AZ171Broker and AZ171Server processes would need access, this error message will appear. Even when those processes run under a special service account which is a member of ZyqadAdministrators.
But DCOM uses something called impersonation, in short: the AZ171Broker process acts as if it was running under the normal user's account logged on to the client computer, and so it failed to access files from the installation folder.
On the other hand, TCP/IP has no concept of accounts or impersonation. It just knows addresses and ports. That is the reason why this works.

Problem Statement: How do I run Aspen HYSYS on a remote machine? | Solution: You have to have OTS installed on the same server that has Aspen HYSYS on it. It also needs to have CIMIO for OPC running. OTS provides a connection between the Aspen HYSYS simulation and an OPC server (which resides with the OTS). First, you would build a simulation in Aspen HYSYS with the PID loops that are going to be in DMCPlus. After the simulation is working, start OTS and open Aspen HYSYS within OTS. Then map the tags within Aspen HYSYS to an OPC tag list. Once it is done, you can configure OPC server and start it. Then you can run the simulation.
Once the system is running, the OPC server is available for any OPC client. In this case, the DMCPlus controller can connect to it from the DMC server using the logical devices name that was established on the OTS server. As far as DMCplus knows, it is connecting to a remote DCS using OPC client.
Real time Aspen HYSYS does use a lot of CPU and OTS uses a lot of I/O resources so make sure that the OTS server can handle both Aspen HYSYS and OTS at the same time.

Problem Statement: How to deploy token licensing for APC products - switching from non-token to token licensing.
Assumptions
1. aspenONE versions V7.2 and V7.3.
2. Previously using a perpetual or term license.
3. A current and existing SLM network license server hosting the license.
4. New token license file is valid, has correct locking information and is a token-type license.
Notes
1. APC machines will need some downtime for rebooting.
2. Recommend to do this with a single machine, with the least impact in the even that you need to recover. A non-production machine will only Desktop tools is preferred to be chosen first. This will allow you to get familiar with the steps.
3. Please note that the conversion step is not reversible with published tools. In the event of conversion failure and there is a need to reverse the licensing from token to non-token, registry update is necessary. Please contact Support. | Solution: 1. Deploy the new token license file at the current SLM network license server.
a. Stop the 'Sentinel RMS License Manager' service from the Services control panel.
b. Replace the license file (and dongle as required).
c. Restart the 'Sentinel RMS License Manager' service.
d. If your license file is deployed successfully, you should be able to identify the licenses through SLM license profiler.
2. On each APC machines, switch the licensing scheme from perpetual/term to token licensing.
a. Use the token utility tool from kb134558. See the instructions from http://support.aspentech.com/webteamcgi/SolutionDisplay_view.cgi?key=134558.
b. Run the APC License Scheme Selector Tool.
i. The tool can be started through ?Start \ Programs \ AspenTech \ Common Utilities \ APC License Scheme Selector?.
ii. Select either APC or APC (Olefins) - depending on the nature of your contract and plant type.
c. If this machine as DMCplus desktop tool installed, run the DMCplus Model. If license is checked out correctly, this desktop tool will be started successfully. In the licensing information (Help \ About), it will also show that license feature APC_Builder is being checked out.
d. Reboot the machine.
i. For AW machines, please ensure that you stop the collection tasks (in AW Maker) and Infoplus.21 before rebooting.
ii. For online machines, please ensure that you stop the controllers and save the current values to CCF (as needed). After rebooting, please ensure that the online controllers are checking out licenses and not reporting license errors.

Problem Statement: Why I am getting error message Error while checking out license (feature name) returned error: SLM Configuration Information in Production Control Web Server and error 18.
For example, while trying to load Aspen DMCplus controller online, it displays this same error message in valid.err, while Aspen DMCplus model, build and simulate works fine without any license errors. | Solution: There could be multiple reasons for Error 18, while checking out license for any Aspen product features one of which being incorrect bucket configuration. Other reasons could be:
- License file not placed at the correct location
- Key expired at a past date
- SLM communication ports not open
- All available tokens consumed
In thisSolution, incorrect bucket configuration for the SLM_APC_MV feature has been discussed.
At times, some of the license features in a particular license is available in different bucket other than the default bucket. The bucket for any feature in a specific license could be found out using SLM License Profiler-> Load information-> View licenses.
A bucket is a container inside an SLM license file of type Network that allows grouping license keys.The first bucket is indicated as the Default bucket.
Now, if a license feature (SLM_APC_MV) is available in a bucket other that the default bucket, which is bucket #3 as per above example and SLM Configuration Wizard is not configured to pick up license from that bucket, it will show up license error when we will try to access the Aspen DMC plus online applications.
The error message in the valid.err file will be - Error while checking out license (SLM_APC_MV) returned error: SLM Configuration Information.
Also, Error 18- License for the specific product couldn't be found, will be seen in Aspen Production Control Web Server screen.
TheSolution to this problem is to configure the SLM configuration wizard, so that it can pick up license from all the available buckets at runtime. To configure the this setting, go to Start-> All programs-> AspenTech-> Common utilities-> SLM configuration wizard and select YES option for “will you be connecting to network server”.
On the “Servers” page, make sure that your license server is available. Then check the option “Search Configured Servers for all available Buckets at run time” as shown below and proceed next till finish. This will configure SLM configuration wizard to pick up license from all buckets.
When we select “Search Configured Servers for all available Buckets at run time”, it will bring up all the available buckets for the specific license.

Problem Statement: Is there any limitation to the number of tags in the collection list? | Solution: There is no limit to the number of tags in the collection list, however there are some considerations to be made.
1.) Consider the setting of EOFCHOICE (End-of-file choice). It is not recommended to use option1, where the
binary input file becomes a circular file, instead use options 0 or -1 which puts a limit on the binary file.
2.) Large collection lists may require multiple extractions, approximately more than 2000 tags.
3.) Consider the setting of LISTSZ - List size maximum for Connect. The default setting of -1 says to read the
the entire list. Setting a value to LISTSZ will break up the list into multiple Cim-IO lists of maximum size of
LISTSZ. The appropriate setting for this can be dependent on the interface.
4.) Consider using cache reads, seeSolution 129885 for configuring.

Problem Statement: How do I manually register the Excel Datasheet Editor add-in? | Solution: If ABE has been properly installed, the Excel Datasheet Editor should have been properly registered and added to Excel. However, in rare instances, the add-in will be lost and will need to be manually re-registered.
Before proceeding, it is important to make note of whether 32-bit or 64-bit Microsoft Office is installed. ABE only supports 32-bit office. If an ABE installation was performed on a machine with 64-bit Office, the Excel Datasheet Editor add-in will fail to be registered, and there is no workaround but to uninstall 64-bit Office, install 32-bit Office, and reinstall ABE.
1. Make note of where AZExcelDSAddin.dll is located.
By default, the AZExcelDSAddin.dll should be located in C:\Program Files\AspenTech\Basic Engineering V8.8\UserServices\bin, but it may be different if the user chose a different directory to install ABE in. Also, if using a version other than V8.8, look in the folder corresponding to your version.
2. Launch command prompt as an Administrator and enter cd C:\Program Files\AspenTech\Basic Engineering V8.8\UserServices\bin.
If ABE was installed in a different directory, replace the path with the correct one. Also, if using a version other than V8.8, replace Basic Engineering V8.8 with your version.
3. Navigate to C:\Windows\Microsoft.NET\Framework\<latest version>. Replace <latest version> with the folder name corresponding to the latest version of Microsoft .NET Framework installed on the machine. In this example, the latest version is v4.0.30319.
4. In command prompt, enter C:\Windows\Microsoft.NET\Framework\<latest version>\regasm.exe AZExcelDSAddin.dll /codebase.
Remember to replace <latest version> with the latest version of .NET Framework on your machine.

Problem Statement: Why am I Getting error when Checking Licenses for Smartstep? | Solution: When a CCF is modified to Enable SmartStep / SMSTENB = 1 or to remove the selection to Enable SmartStep/ SMSTENB = 0 it is necessary to unload the controller and then reload the controller. A reload only will not detect the change and will continue to try to checkout / keep the SmartStep license.
Regarding any Advanced Process Control online applications, DMCplus, SmartStep, AspenIQ, Apollo, if the location of a license server is moved or renamed, it is recommended to stop and restart the application, in order to detect the changes made to the SLM Configuration to look to a new / different license server.

Problem Statement: What are the things that I can check when I get the below error message on clicking part definition in graphic definer? | Solution: Mainly, there are two reasons of occurrence of this error message:
1) Dll file is corrupted
In RAD applications each menu item is implemented in a separate DLL. The Part Definition command is handled by the 'AZ161GDPartDefinition.dll' ( v 7.0), which by default is located at C:\Program Files\AspenteTech\Aspen Basic Engineering v 7.0\UserServices\bin
Either the registry key for this command has corrupted or the DLL itself got corrupted. There can be following way outs,
- Re-register this dll.
- If that doesn't help, you can replace this dll file with a good dll file.
- Final option is, re install zyqad.
2) Intergraph version is not compatible.
Both the application use the Intergraph graphics tool, RAD. If there is a different versions of RAD in Aspen Basic Engineering than Smartplant, that can be the reason of error message. Make sure versions of both applications are compatible and can exist on same machine.

Problem Statement: Sometimes a .NET application takes long time to start up (several minutes), but only on machines without Internet access. The delay occurrs while a .NET security component awaits a response from http://crl.thawte.com. The security component attempts to get an updated list of revoked code-signing certificates, so it could be absolutely certain that the assemblies in question had not been tampered with. So this also could generate a substantial increase in the start up time of the ABE Excel DataSheet Editor. | Solution: In order to improve the start-up time in the Excel DataSheet Editor, you have to follow this procedure:
1. Open Internet Explorer.
2. Go to Tools | Internet options.
3. Click on ‘Advanced’ (Tab).
4. Under ‘Security’ option, uncheck ‘Check for publisher's certificate revocation’.
Now the program will start a few seconds faster.

Problem Statement: What is the effect of setting MXNIMB to greater than 0 on a Ramp Variable? | Solution: MXNIMB specifies the maximum number of cycles for which dependent variable ramp imbalance in the steady-state solver will be permitted. For ramps where MXNIMB >= 0, the steady-state solver attempts to balance the ramp on every cycle.
After MXNIMB consecutive cycles where the steady-state solver cannot balance the ramp, the controller will turn OFF. For ramps where MXNIMB = -1, the steady-state solver does not attempt to balance the ramp.
If we are not at the limit cycle, the controller calculates the upper and lower limit rate of the ramp to keep it within the safety limits:
In the next example I have a ramp variable with MXNIMB=576, I used DMCplus Simulate and leave it running until it reach steady state, look how at the end the ramp is balanced and you don’t see more changes on the CV:
Note that in the simulation all Feed Forward variables are constant; in normal operation this is not true so when you see a change in a FF you might see a message like this on the control objectives for that FF:
Observed “Feed Forward Variable� changing by 0.668792 (maximum) over previous 60 hours impacting:
“Ramp CV� (max possible 0.00 change, actual 1.46 range)
The message is pointing that the ramp steady state target is 0 (balance ramp) however you are at 1.46 and the controller needs to take action in order to balance the ramp
