Response of the new version:
If a Save Parameter Set in Controller is triggered with the EASY Starter, then after successful acknowledgement all parameter sets of the EtherCAT slaves connected to the controller are stored in the controller and the controller can be switched off.
What happens?
The parameter sets of the devices connected to the controller are not stored in a power-failure-proof manner. After switching on the power, the "old" parameter set is still used.
When does the behaviour occur?
The EASY Starter is connected to a Lenze controller. On the EtherCAT master of the controller there are Lenze devices that support central parameter set maintenance (i550, i700, i950, I/O1000).
In the controller, Save Parameter Set is triggered ("Save" button), which uploads the parameter sets of the devices connected to the controller and saves them in the boot project of the controller.
After the EASY Starter has responded, the controller is switched off.
Which products are affected?Controller c520 from V1.0
Controller c550 from V1.0
Controller c750 from V1.0
EASY Starter from V1.18
Short-term measures:
Do not switch off the controller immediately after the EASY Starter reports the successful saving of the parameter sets. Wait until the message "Parameter set upload done" appears in the controller logbook. Depending on the number of devices, this may take several minutes.
Evaluation/Recommendations:
When saving the parameter set of a Lenze controller, the parameter sets of the devices connected to the EtherCAT master of the controller are uploaded and stored in the controller. Before the saving process is finished, the EASY Starter reports the successful saving of the parameter sets. If the controller is switched off at this moment, the parameter sets of the connected devices are not saved.
