PURPOSE:To form a control system optimum for an object process by providing an input/output controller which fetches an input signal, performs control operation and generates an output signal, an operating device performing its operation and a transmission line connecting the input controller and the operating device so as to attain mutual communication. CONSTITUTION:A controller 2 as the input controller, the analog input/output controller 3 and a digital input/output controller 4 are connected by the transmission line (l) so that they are communicated mutually. The connecting information of each input/output controller (2, 3, 4) is stored in a RAM of the operating device 1 and then transferred to a RAM of the controllers 2, 3, 4, where the information is used for the functional check. The information is stored in a ROM by a ROM writer built in the operating device 1 and fetched in each input/ output controller (2, 3, 4), thus the control/supervisory system is completed. |
