Profibus error in AC900F redundancy
For somehow my profibus redundancy is not working. when I isolate CI930F from the controller it works fine. But when I attach it, I get "redundancy error " in control builder F.
1) i have a new grey type controller with new style CI 930F and the other controller is white which is the old one. CI930F of this is attached with TU915F for the line A. my question is can we mix and match. Has anyone tested it?
2) Why do I have redundacy error display status?
3) I have only one battery for the controller now.. ( ordered it from ABB but little delay because of the holiday). Do I need to have the battery to test redundancy? I have SD card for sure.
4) when downloading the project to controller, one controller displays " bootloader waiting" and resume its state after 2-3 mins. Is that normal? What does it mean?
Need your advice..
