Early on we had the same problem. What we found was that there was too =
much difference in length between fieldbuses which made the attinuation =
different. We disable auto switching because every time it wanted to =
switch we'd get these errors. Now if a bus fails it will still switch but =
we don't get the recurring errors.

the same FBM3 address POLDD3.

We tried to:
1) Make an EEprom update=20
2) Change the FBM
3) Move the FBM in another place
4) Change the FBM head
5) Unwire all the signals coming to the board
Problem keep the same: does anybody know how to fix the problem?=20
Thank you in advance.
