?What happens?
The parameters of the I/O 1000 CAN bus coupler are reset to their standard settings. Depending on the baud rate set, the CAN bus does not change to Operational.
When does this behaviour occur?
After a Reset (cold), the controller resets all parameters of the I/O 1000 CAN bus coupler to their standard values if the 'Create all SDOs' checkbox has been activated for the bus coupler on the 'CANopen Remote Device' tab.

Short-term measures:
Deactivate the 'Create all SDOs' checkbox for the I/O 1000 CAN bus coupler.
Evaluation/recommendations:
If the 'Create all SDOs' checkbox is active, all parameters of the slave will be transferred to the slave, independently of the fact if the standard values have been changed or not. As a result, for the I/O 1000 CAN bus coupler the parameters will be reset to their standard settings.
