PROFIBUS DP: configuration of DP master bus %1 has been changed
%1 = Number of the affected bus
The PROFIBUS configuration on the DP master was changed during operation, e.g. by downloading a new hardware configuration via Step7. Since it is possible that the cycle data have changed, operation cannot be continued and a warm start is required.
If the DP master functionality is within the PLC (as on the 840Di), the PLC will have been stopped for the download and alarm 2000 (PLC sign-of-life) output.
