DCS 800 Fieldbus Parameters Reset Itself
We are running DCS 800 with PLC via RPBA-01 PROFIBUS DP Adapter module. The drive had been running properly as usual until it suddenly stopped today. After checking the control panel, i noticed that all the fieldbus parameters (group 51) (except parameters 51.01 and 51.02) have reset to default values. As far as i know, the fieldbus parameters can not be changed without external intervention.
To solve the problem, we just replaced the adapter module and its connector with new ones and adjusted the fieldbus parameters. The drive is running properly for now. But i am confused about how the fieldbus parameters were set to default(factory) values. Is it possible that the drive's pcb card caused to resetting default values? Or what do you suggest for permanent solution?
Thanks in advance
it's really a very strange failure. I've never had such a thing, so the suggestion I give you is, as you did, replacing the RPBA module.
I can not explain why the data are back to the default, unless a failure is also on the drive, but I think this can be ruled out because you tell me it's working now.
What kind of PLC is there as a master?
