So its always a misunderstood topic and a tough one givin the siemens TIA portal is so hard to navigate and add devices if you don't know the order of operations...
ANYWAYS, I have a Fanuc on-site and they added a 4th machine. No big deal right? Wrong... I cant get the FANUC side to update. and ive got to the point where im determined im missing a step. Basically you can see the card pulling the i/o data on the status/profinet page but the robot/profinet setup will not read the new configuration or new I/O coming in.
here's what i've done in the past
- robot start mode: stop
- cycle power,
- Load config too Cp1604 card, via TIA portal.
- robot start mode: Run
- cyclepower
