For the PCD, there are various flash memory modules for different applications. Some of these modules are explicitly designed for a particular use (e.g. the PCD7. R500 for user program backup). However, there are other modules available for various types of storage (e.g. the PCD7.R551M04, which contains 1 MB of memory space for the user program backup and 3 MB the file system).Most flash memory modules are simple cards (PCD7.Rxxx), which can be plugged into a PCD2.M5xxx0 in Slot M1 or M2.Flash memory modules for the file systemApart from the flash memories mentioned above for backing up the user program memory and DBs, there is another type of flash memory available for files. These memory modules can be used to save "PC-readable" files such as web pages, images or log files. The content of these flash memory modules can be accessed via the web server, the FTP server (for PCD2 with Ethernet interface only) and the user program.
