1. A system for resolving inconsistencies in device models within a process control system while executing a control process, the system comprising: a process controller having a first model of an entity of the process control system; a control process execution engine having a second model of the entity of the process control system, wherein the control process execution engine is adapted to provide a control instruction to the process controller based on the second model of the entity, and wherein the process controller is adapted to execute the control instruction based on the first model of the entity; and a control execution object that detects a difference between the first and second models of the entity during execution of the control process and generates a prompt in response detection of the difference, and receives an operation instruction regarding continued operation of the control process, wherein the operation instruction comprises one of continuing execution of the control process or aborting execution of the control process.
