Hey guys,
I am having some trouble with one of our profibus node on the network. We have an S7317 PLC (DP MASTER) with 5 Siemens slaves and 2 ABB IRC5 robot controllers.
**This is an intermittent problem
Only one robot is loosing communication with the master, and all other devices are still communicating. The robot is not the "end of line" and the slaves daisy-chainned after it are still working fine after the problems occurs. To get these info, I do a network diagnosis in the PLC with FC125-DPDIA.
Action I've already did:
We tried to re-install the profibus card - No change.
We tried to redo the connectors - wont do anything.
We tried to swap the DP Adapter from one robot to another - Problem is still on the same robot.
We finally tried to change all the cables - problem occured again.
Currently, I am solving the problem by simply rebooting the robot controller. Then it starts working for an undefined period of time. We have several other robots, all linked to a S7317 via profibus, and they are all working fine.
I think that I may have to change that robot controller, but im looking for a more "easy" way of doing this.
Any thoughts ?
Thanks a lot,
Jonathan Fournier.
