Hello,
We’d like to create communication between PLC M340 and specific device (BMS). We try to use AB7319 with ACM software to communicate but we still have “Error active” in diagnosis table.
Wiring is correct (we did many check). So we suspect configuration of ACM. From CAN side, we have 1 transaction as “consume” only for the begining.
LED 5 is blinking red but as soon as we download new configuration, LED 5 goes green and at the end come back blinking red.
“Error active” is misleading. It means there is an error frame, but no error message. If there was an error, it would be “Error passive” or “Bus off”. So in this case, there is no problem.
