Hello!
I need to communicate from a CompactLogix to a Unity based PLC via modbus tcp. I have a PLX32-EIP-MBTCP gateway configured to the point where both PLCs are attached and can see the gateway.
I have the EDS file for the gateway and was able to set it up in my ethernet tree in Logix. It appears to be configured correctly and connects just fine.
My questions comes down to mapping. I'm not sure which bits to use for the In/Outputs. Also, do I have to do anything in the gateway to make sure the translation pulls through correctly or for simple bit to bit communication is it pretty well plug and play (after setting the IPs).
Thanks!
