S+ sent the invalid signal to I-RTU via IEC104 protocol
I have a project that converts IEC 104 to IEC101 to communicate with Dispatch Center. My DCS Server using S+ Operation v2.1 and I use IRTU (Igrid T&D) to communicate with DCS via IEC104 and Dispatch Center via IEC101 (IRTU act as Gateway converter). This communication is OK but I had a problem that:
- When i restart the S+ Server or restart the I-RTU, all the DI signals sent to the dispatch center becomes Invalid signal quality. All the Analog signals still good because they change frequently. To get Valid DI signals, i must to force these signal from ON<->OFF and take a lot of time.
I have ask support from Igrid and send them the log. They said that the problem from S+ DCS because they only transfer exactly the signal quality which they received from S+ Server
Can you verify if you have the general interrogation signal? It bust be a digital signal, type 100 with the address 0. Is similar to a command. Can you check if it is being sent the general interrogation.? Your issue is due to when the driver goes to not connected, set all signals to CF, and the only way to recover the exception signals is executing a general interrogation
