In order to deal with common cause failure which can happen to the digitalized software, an ECP manual trigger path (sharing the same ECP button) which bypasses the digitalized software and is realized by diversified devices (such as relays) is additionally designed, and the diversified manual command is connected to a No. 2 input port of the PLM module and is called as ECP manual protection hard logic. In the PLM, the trigger command from the 1# input port and the trigger command from the 2# input port are subjected to or operation, and preferably subjected to a backward command from a system such as an NC DCS, and then sent to the field driver.
