Abstract
PURPOSE: To make it possible to back up a faulty control device only with connection change of cables, by providing a function, which discriminates a channel whose cable connects the control device and a device to be controlled, in the control device.
CONSTITUTION: Since control device 1a is used to back up control device 1b when control device 1b controlling channel CH.B becomes faulty, connector 4A of cable 3A is removed from control device 1a, and connector 4B of cable 3B is connected to control device 1a. Then, control device 1a receives the cable identification code from connector 4B and discriminates that the new connected cable is cable 3B of channel CH.B, and control corresponding to the channel is performed. Thus, the faulty control device can be backed up only with connection change of cables.
