I am having issues with communication to an AB PLC over Ethernet/IP.
I am able to “see” the device but I am getting a com fault that my CANopen:I has an invalid connection size. I have it set to 64 in/out INT.
On my gateway param 3000 and 3001 are set to 64
param 3070 is set to 0

Solved by Teamviewer call.
