PROBLEM TO BE SOLVED: To establish communication between a CPU module and other I/O modules by cable, and perform communication with a desired I/O module by using radio communication instead of the cable. SOLUTION: Bluetooth radio parts 18, 18a to 18f are mounted on modules 12, 16a to 16f, and a CPU module 12 executes a sequence program by wired communication with I/O modules 16a, 16b, 16d to 16f connected to a PLC bus 14 through a PLC bus 14, and executes the sequence program to an I/O module 16c which is not connected to the PLC bus by radio communication with the I/O module 16c using the Bluetooth radio parts 18 and 18c.
