PURPOSE:To increase both the circuit efficiency and the speed of job execution and then simplify the control for a system in which a main controller and the input/ output devices are connected to a serial circuit, by performing a circuit control in correspondence to the execution program of the main controller. CONSTITUTION:In case a telegram of the receive-ready RR frame is transmitted and received in a communication between the main controller 50 and the input/output devices 71-74 based on the job program, the data is transmitted among the controller 50, monitor panel control part 75 and remote monitor 76 respectively. In this way, the interruption factors of the control part 75 and the monitor 76 can be put into the controller 50 without setting up any job program. |
