PURPOSE:To enable an operating switch to be disconnected from external control, as required, by a construction wherein whether external control by a central controller is to be performed can be selected by each operating switch. CONSTITUTION:A command inputted into a standard interface circuit 37 is decoded by a computer 40. Where the decoded command is one for operating the n-th sub-machine and the n-th external control lamp 14 is turned ON, processing is conducted so as to operate the n-th sub-machine, and the n-th operating command lamp 15 is simultaneously turned ON. Where the command is one for stopping the n-th sub-machine and the n-th lamp 14 is turned ON, processing is conducted so as to stop the n-th sub-machine, and the lamp 15 is simultaneously turned OFF. Although the operation and stopping of the sub-machine can be externally controlled through the standard interface, control by a host machine 1 can be performed independently of the external control, by turning OFF the lamp 14 by operating the operating switch 13, even when the external control is conducted. |
