Hi Drives experts,
we have 32 Siemens master drives runing on profibus with S5 155U on Im308c. Now one drive 37Kw 6ES7027-2ED20 runing with CU2 and CB1 card became faulty. we Have another Spare 45KW (6ES7031-2EE20) Drive. we installed 45KW drive inplace of 37Kw drive, we installed CU2 and CB1 card. with drive monitor software we reset parameter, change MLFB no. and download old parameter file to drive, then change profibus address and then fix profibus. drive give OK status. Then we started with profibus it run ok. after some time two diffrent dive on this profibus triped with F082 (communication fault). we try it two time but same result while profibus address is same as before.
Please Help me why is it happen?
Regards,

Most likely after setting the Profibus parameters online you haven't 'saved' them.

It's been a while since I've used it, but as I recall from using the "Drives ES" software on Siemens drives, It was one operation to set the parameters on the drive and another operation to 'save' the configuration to the flash memory on the drive. If you didn't do this then it would revert back to prior saved configuration when power goes off.
