Eliminated from:
E94AYCER communication module FW 1.30
Behaviour of the new version?
The new firmware is booted without problems when the module is started.
What happens?
Although the Profinet master has switched the module to process data mode (Data Exchange), the module remains in bus state 'No Data Exchange' (L-C13861 / 14861) and indicates the value 5 (miss consumer) in the bus error code L-C13879 / 14879). In this state, process data is not accepted and transmitted by the module.
When does the problem occur?
The problem may occur after a very short mains switching of the Profinet master (approx. 5 seconds).
Which products are affected?
E94AYCER communication module FW 0.70, 1.00 and 1.10
Possible diagnostics?
The error can be identified via the bus state codes and bus error codes.
Short-term measures/recommendations?
None.
Evaluation:
If the error described before has occurred the module cannot accept process data. Therefore, the plant cannot be used.
