Short Presentation on how to connect an ABB IRC5 Robot Controller to a Rockwell CompactLogix PLC via Ethernet. I found the documentation from both ABB and Rockwell somewhat lacking and maybe even a bit confusing considering the simplicity of the connection. There are still a few unanswered questions regarding the fact that ABB uses one word for each I/O point whereas Rockwell uses bits from the only the first 8 words sent. Just FYI for the group.
I’ve removed two ABB robots that were communicating to an AB CompactLogix via ethernet using the IRC5 slave only fieldbus adapter that we installed a year and a half ago. Those didn’t have enough payload and we exchanged with larger units but these have Ethernet master/slave. The ethernet m/s operates through a DSQC612 card. I’ve gone through every manual I can get my hands on and talked with Tech Support. We loaded the EDS in the AB PLC and matched our sizes to 64in x 64out. No errors on the robot at all. The PLC shows the yellow triangle on these modules that is not communicating. We are at a loss / standstill. Any insight you may have would be appreciated. ABB2400 running RobotWare 5.15.
