The following figure demonstrates execution of ECAT_START_COM:

With execution start the bus communication is enabled. Communication state of the Master is checked and it’s waited until the communication state is ‘Operate’.

Execution of the Function Block was successful if the master was changed to the communication state ‘Operate’. If the master is not in this state within the specified timeout, execution of the Function Block is failed and the bus communication is disabled again.
