?What happens:
If the safety controller c250-S is inserted into the PLC Designer project via the context menu command 'Search devices' of the EtherCAT master, then the error message appears after downloading the appliication to the safety controller:
Service handler is not available or has returned an error.
When does this behaviour occur?
The behaviour occurs if the EtherCAT master with version 3.18.2.0 is attached in the project and the safety controller with the older version 1.0.0.2 was inserted. With the menu command 'Search devices' the safety controller c250-S with the older version 1.0.0.2 is inserted.
Which products are affected?
PLC Designer from V3.20
Short-term measures:
Insert the safety controller c250-S manually with at least version 1.0.0.4.
Evaluation/recommendations:
If an outdated version of the c250-S safety controller is used in the PLC Designer project, this leads to an error message during the download. A newer version 1.0.0.4 of the safety controller is available and can be inserted manually into the project.
