Corrected from:
Cabinet Controller c520 V1.7
Cabinet Controller c550 V1.7
Cabinet Controller c750 V1.7
Response of the new version:
If an init error is detected by the EtherCAT master after a project download or a cold or warm reset of the Lenze controller with an inserted EtherCAT device module, this can be rectified by subsequently setting the EtherCAT device module to the 'Operational' state. Afterwards, the process data communication works.
What happens?
The EtherCAT device indicates that it is correctly configured and is in the Operational state. Nevertheless, the EtherCAT device module neither receives nor sends process data.
When does the behaviour occur?
The behaviour described above can occur sporadically after downloading a new PLC project or after a reset cold or reset warm.
Which products are affected?
Cabinet Controller c520
Cabinet Controller c550
Cabinet Controller c750
EtherCAT Device Modul
Short-term measures:
Perform a new cold reset or warm reset or set the EtherCAT device module to operational via EtherCAT afterwards.
Evaluation / recommendations:
Under the conditions described above, process data communication via the EtherCAT Device Module does not start. An application solution is described under Short-term measures.
