Abstract
PURPOSE: To prevent the working unable state for the input/output device connected which is caused by the cutoff of the input/output interface line or the fault of the channel function, by connecting the input/output device to the two channels of the terminal unit.
CONSTITUTION: The terminal unit 11 having the input/output channels 12W19 and to be controlled by the control program 20 is provided, and the input/output devices 21W31 are connected to the unit 11. In this case, the devices 21W25 plus 29W31 are connected to a channel 12 of the unit 11 via the input/output interface signal line 32, and the devices 21W25 plus 26W28 are connected to other channel 13 via the interface signal line 33. Furthermore, the devices 26W28 plus 29W31 are connected to the channel 14 via the interface signal line 34. The a control becomes possible for each of the units 21W31 via the signal lines 32W34, thus preventing the working unable state of the devices 21W31 which is caused by the cut-off of the signal lines 32W34 or the fault of the channels 12W14.
