The configuration is established and can then be switched to online state (OPERATIONAL).

In Config/FreeRun mode the System Manager display alternates between blue and red, and the EtherCAT
device continues to operate with the idling cycle time of 4 ms (default setting), even without active task (NC,
PLC).
