J1939 communication between MC43s : value change with no reason
C. Drouaud 2 years ago in IQANdesign • updated by Gustav Widén (System support) 2 years ago • 1
I have a system with 2 MC43s, communicating with a J1939 communication. One of the digital parameters sent from one MC43 to the other change its value between what is sent and what is received.
The MC43-1 is sending a false value (0) and the MC43-2 get a true value.
How can that be possible ? How can I resolve it ?
Thanks in advance,

It sounds as if there could be a mistake in how the application was designed, so I took the liberty of re-categorizing this as question. But it will be hard to troubleshoot without seeing the full project file. Perhaps you could reach out to your local support contact if you need a second pair of eyes on the file.
If I would take a guess, it sounds as if you might have mapped the J1939 messages differently in the two applications.
