Hello, I'm hoping someone can help me please.
We have a PCM301 card that has stopped working for some reason on a 90-30 PLC (possibly due to a duff battery which has been replaced). It is being used to do some maths and move the results to some analog outputs. I have a megabasic program for it but when using the PCOP software on a windows laptop, I have no comms. Pressing the restart button doesn't seem to make a difference either. I'm using a 9-pin female to 25-pin male (connected to port 2 of the wye cable). I've tried various comms settings and serial cable configurations but am getting nowhere. On another thread I found a pinout that does make the US2 led on the card flash but still no comms on PCOP. The pinout I have is:
2-2
3-3
7-5
5-7
8-4
20-8
Any help would be greatly appreciated.
