ANALYZING COMMUNICATION CONFIGURATION IN A PROCESS CONTROL SYSTEM
Each network message configured for transmission from a sender to a receiver IED across an Ethernet switch-based communication network of a PC/SA system is evaluated, and a graphical representation respective of process related operational aspects of each IED involved is generated and displayed. Sender and receiver IDs are determined from a logical data flow description that is part of a formal configuration representation of the PC/SA system. One of a plurality of operational aspects of the process is retrieved for each IED from the formal configuration description. Generating the graphical representation of the system includes forming groups of IEDs with identical operational aspects. For each group of IEDs, the respective operational aspect is indicated or displayed. A user may analyze the communication configuration of the system by looking at the graphical representation and determine the consequences of IED failures or engineering errors on other IEDs.
