<p>PURPOSE:To smoothly control a system on the whole by referring to a table and disconnecting a power source after all work stations finish jobs even when a power-off command arrives from a master station. CONSTITUTION:The command from the master station 15-1 is inputted to a power-off control part 17 through a local circuit control part 16. The control part 17 refers to the table 13 and when the control part 17 decides that a station 15-n is in job execution from the '1' state of a power bit (n) corresponding to the station 15-n, the control part 17 refers to the table 13 at intervals of, for example, one second according to a timer 14 without disconnecting the power source 12. Then, when all power bits in the table 13 become '0', there is no work station in job execution, so the power source 12 of a station controller 10 is turned off for the 1st time.</p> |
