| 摘要 |
The present invention is concerned with an analysis of a communication configuration in a Process Control (PC) or Substation Automation (SA) system, by evaluating, in a particular manner, every network message, and/or respective message source, configured for transmission across a communication network of the system. From a logical data flow description that is part of a standardized configuration representation of the PC or SA system and which includes, in the form of control blocks, formal information for every message, receiver IEDs arc retrieved or determined. For each retrieved receiver IED, the totality of all network messages destined for or directed to this particular receiver IED is evaluated or processed, e.g. in view of a subsequent network load analysis, Virtual Local Area Network assignment, or graphical display of the data flow. Exemplary network messages of interest include cyclic point-to-point reports, as well as, in terms of IEC 61850, periodic or repeated real-time multicast messages (Sampled Values SV) and event-based multicast messages (Generic Object Oriented Substation Events GOOSE). |
