PURPOSE:To enable other stations to stop and start operation simultaneously when one station stops and starts operation, by providing an interface means, which transmits a simultaneous stop signal and a simultaneous start signal, among the stations. CONSTITUTION:When a master station 1 and a work station 2 detect stop conditions, an interface means consisting of maintenance diagnostic adapters 3 and a maintenance diagnostic cable 5 sends a simultaneous stop signal to the station 1 or 2, and the other station 1 or 2 having receiving the simultaneous stop signal outputs an interruption signal to stop the processing execution of a program. Similarly, when the stations 1 and 2 output the simultaneous start signal, the work stations having the fitted adapters 3 start operating simultaneously. Therefore, the maintenance diagnostic is performed easily and rapidly without absence of data required for the maintenance diagnosis. |
