What happens?
The download of the SafetyApp into the Safety Controller c250-S is not possible. The error message appears:
Service handler is not available or has returned an error.
When does the behaviour occur?
If an EtherCAT slave, which is located before the safety bus coupler, is deactivated in the PLC Designer, the PLC Designer can no longer go online with the c250-S safety controller.
Which products are affected?
PLC Designer V3.15 in connection with Safety Controller c250-S.
Short-term measures:
Delete unneeded EtherCAT slaves from the PLC Designer project instead of disabling them.
Evaluation/Recommendations:
In the project planning phase not necessarily all EtherCAT devices are connected to the controller. In this case it may be necessary to deactivate these EtherCAT devices in the PLC project. This function restriction means that logging into a c250-S safety controller connected to EtherCAT is not possible if EtherCAT devices are deactivated before the safety controller.
