I am not using a PC for this; I am using another PLC - in this case Opto 22.
I have tried communicating via PCOM using both binary and ASCII protocols shown in the PCOM manual. I have not been able to get either to work. I can see that the two establish a connection (socket 2), but the V350 does not respond to the query.
For the ASCII version, I just tried the simple "Read Real Time Clock", which is "RC".
Is there anything else I have to do on the V350 side to prepare it for PCOM communications?
Does this work only over a particular port on ethernet?
Thanks for your help
