Simulation system for multi-node process control systems

摘要

A simulation system attaches to a configuration database for one or more fully configured nodes of a process control system and copies the modules within those nodes into one or more simulation computers as simulation modules. The simulation system includes an algorithm that automatically creates a reference parameter module for each of the copied nodes that stores a reference parameter for each of the inputs, outputs or other references to signals external to the nodes. In the case of the Fieldbus function blocks, the simulation system automatically creates a function block within the simulation workstation in the protocol of the controller node which mimics the operation of the Fieldbus function block, and then creates the simulation system having those mimicked Fieldbus function blocks operating as if they had originally been configured to be in the controller being simulated, instead of within a field device external to the controller.
