PURPOSE:To omit an exclusive line for controlling turning-on of a power supply by forming a power supply turning-on controlling part always supplied from a sub-power source in parallel with a work station control part. CONSTITUTION:A CPU5 constituted by a work station (WS) control part 1, a power supply turning-on controlling part 2, a main power supply 3, and a sub- power supply 4 forms a remote power supply turning-on control system for controlling the turning-on of the main power supply 3 to plural WSs 10-21. The power supply turning-on controlling part 2 is connected to WS interface lines 18, 28 in parallel with the WS control part 1 and the sub-power supply 4 supplies electric power to said control part 2 even if the main power supply 3 does not supply electric power to the central part of the CPU5. The control part 2 executes specified WS polling, and if the polling is valid, power supply turning-on signal 8 is outputted to the main power supply 3. Thus, the main power supply 3 supplies power to said central part and then the WS control part 1 controls the WS10-21. |
