PROBLEM TO BE SOLVED: To provide a PLC device in which IO setting is variable by changing IO setting without changing the OS of the PLC device. SOLUTION: This PLC device 10 is provided with an IO table storage part 11 for storing an IO corresponding table for defining the correspondence of a physical address to a logical address, an IO module 12 for inputting and outputting a signal, and an inputting and outputting part 13 for transmitting and receiving a signal with the IO module 12 and allocating the physical address to the IO module 12. In this case, an IO access part 14 is connected to the IO table storage part 11 so that the IO corresponding table stored in the IO corresponding table storage part 11 can be referred to. A PLC main body part 15 executes prescribed processing cooperatively with the IO access part 14.
