1131 Communication issue with MP
Thread Content
Due to process-related reasons, one of our company’s unit systems was shut down for nearly 2 years. The project has been restarted recently, and the system is powered on properly; however, the 1131 unit cannot communicate with the MP. Attempts to reinstall the program to activate it have also failed. The cause of this problem remains unknown. The hardware indicator lights are all functioning normally – the TCM card’s link light is on, while the TX and Rx lights do not flash. We seek advice from those who are more experienced in this area
I can’t download it. What message does it show? It’s best to upload a screenshot of the hint. The TCM4351B is usually configured in a redundant manner, so it’s unlikely that both of them will have issues. Can you ping them to check connectivity?
When pinging fails and it shows \"no response\", how can engineers distinguish between the software dongle and the operator station?
The software dongle is for the host computer Intouch; it has nothing to do with installing your program. If that doesn’t work, then use TRICON’s programming cable to download it via the fourth serial port of the TCM.
