Which products are affected?
Fieldbus function module Profibus-DP, software version < 1.0
What happens?
Code L-C1513 contains the response-monitoring time for the process data communication. This time is passed on to the slaves by the Profibus master during the initialisation phase of the Profibus network. The time is displayed under code L-C1513 which has been defined as display code. However, this can be changed.
When does the problem occur?
In case of all Profibus fieldbus function modules (software version < 1.0) code L-C1513 can be modified by using the keypad or GDC.
Possible diagnostics?
If the set process data monitoring time of the Profibus master does not agree with the value under code L-C1513 the behaviour described above will occur.
Short-term measures/recommendations?
Do not use the keypad or GDC to write this code.
