MM440 drive and F0070

Hi,

I placed an MM440 as a slave of an S7 3152DP in a Profibusnetwork with 4 repeaters.
Sometimes the error F070 occurs on the MM440.
I checked the profibussignal with an oscilloscope and found this to be OK.
I already replaced the profibus module.

The telegram off time P2040 is 20ms as default.
In the diagnostic buffer of the S7 3152DP the error appears as slave with profibusadres 10 and missing etc.


Shoud increasing P2040 be of any help

Tnx
