Abstract

PURPOSE:To inform missing of an external signal data even if it occurs by sending the state of a supplied external signal according to the timing generated by a timer provided to an external signal input controller, from a transmission section as an external signal informing data. CONSTITUTION:An external signal input controller 5 detects the state of external signal input terminals 2, 3 from an external signal input device 4 independently of the presence in the state change of an external signal according to the timing generated by a timer 15 and sends the result to a transmission section 7 as an external signal informing data. If the external signal data 24 sent by the external signal input controller 5 at the state change of the external signal does not reach the reception section 9 by a fault of the transmission line 8 due to the external disturbance such as thunder, the reception section 9 sends the external signal informing data sent afterward to the external signal output control device 11 to control the external signal output device 12, thereby outputting the said external signal from corresponding external signal output terminals 13, 14.
