PLC-001, PLC Communication Time out
P1AM-100 communicates to C-more EA9 through P1AM-ETH. I set up P1AM-ETH as 192.168.1.2, and C-more EA9 as 192.168.1.3. I can ping both in the network. Error "PLC-001, PLC Communication Time out" shows on C-More EA9. The orange indicator ACT on P1AM-ETH is flashing.
if you are able to ping both systems, I would say the problem is in your cable, are you using a straight or crossover ethernet cable inbetween them?
@shane717 When I ping them, my laptop, P1AM-ETH, and C-more EA9 are connected to SE-SW5U ethernet switch.
Attached are the programs for P1AM-100 and C-more EA9.
P1AM Driver CmoreV6.52

The example as posted requires that the Arduino Serial Monitor is running. This is so that debug information can be displayed. You can comment out this line of code. Or, if you do have the Serial Monitor running, please post the debug information that is being printed.
while (!Serial){}// wait for serial port to connect.
I get that error code on my CMores when I have an object on screen that is referencing an address that doesn't exist or is wrong from the PLC.
While the error seems like it should just reference an actual com loss to the PLC, my guess is that the object I have with a bad memory address simply times out trying to receive a response from something that doesn't exist, and the error happens because no communication has come back with the data for the object request.
Excel and Xlookup are lifesaver for sorting those out on large Tag DB's
Attached is the monitor screen. I connected the cable to serial monitoring.
I assign the address for PLC and C-more EA9 as ACC example.
I guess something wrong in the configuration on C-more EA9.
