PROFINET communication: Error message 0x8190 occurs at process data length zero (no change intended)
Corrected from:
Servo inverter i950 FW: (no change planned so far)
Response of the new version:
So far no software change in the firmware is planned.
What happens?
PROFINET communication: The error message 0x8190 "Fieldbus: Invalid process data" is triggered unexpectedly.
When does the behaviour occur?
If PROFINET communication is parameterized in the PLC configuration software without IEC module and without module for functional safety engineering and the resulting process data length is 0 bytes.
Which products are affected?
Servo inverter i950 FW
Short-term measures / Evaluation/ Recomendations:
The occurrence of the error message can be prevented by deactivating "Fieldbus network monitoring: Invalid process data":
Set parameter 0x2859:5 = 0 "No response". The default setting is 0x2859:5 = 2 "Warning".
The described function restriction has only very little practical relevance as the described behavior only occurs under special conditions.
