ABSTRACT:
An interlock control apparatus for a plurality of control modules each of which controls driving of at least one piece of equipment is of a simplified structure. The interlock control apparatus comprises slave switching apparatuses corresponding respectively to the control modules. Each of the slave switching apparatuses comprises a multiplexing apparatus that produces a multiplexed signal by multiplexing state detecting signals each of which indicates any of a plurality of states of a piece of the equipment whose driving is controlled by the corresponding control module, a storage apparatus that stores the multiplexed signal, a reading apparatus that reads out the stored multiplexed signal, a separating apparatus that separates the read out multiplexed signal so as to produce a plurality of separated signals, a transmitting apparatus that transmits a predetermined separated signal out of the separated signals to the control modules other than the corresponding control module, and at least one controller that controls driving of a corresponding piece of the equipment based on the predetermined separated signals.
