Freelance Profibus DPM master in Error state
We have freelance 9.2 with redundant system (controller and Node redundancy).For line redundancy we are using RLM 01
System was running last 1 year without errorb ut today we get an error with message like
1.Profibus DPM master in state error IP1
2. Profibus DPM firmware Error
and then some node showing slave not exist and plant tripped.
sorry you had a problem with your system.
Your best chance to find out what happened and how to prevent that from happening in the future is to contact your local ABB support.
If you want, I can have a first look and see if I easily can find out why your plant tripped.
By the way when you say the plant tripped what exactly do you mean? You wrote you have controller redundancy. Did you mean with "plant trip" a fail-over in the redundant pair of controllers?
What version 9.2 do you use? Please provide the build number. See marked number in picture of about-box below:
What controllers do you have: AC 800F or AC 700F?
In case of AC 700F, what Profibus master module do you use?
Are you familiar with getting a diagnostic file out of the controller? If yes, please provide the diagnostic files from primary and secondary controller.
