[?]: How to diagnosticate the profibus-DP in step5?

[iop_p]

Hi everybody,
An old rewind machine used Step5 control sys.
The cup945 can't in Run mode, because it can't detect the profibus loop.
But how can I diagnosticate the profibus-DP loop in step5 software or need some other software??
Thanks to share!
