PROBLEM TO BE SOLVED: To provide production facilities which are expected to improve area productivity by miniaturizing a control board. SOLUTION: Production facilities 100 control a machine for industrial use (an electropress 13, conveyer motors 31 and 33, and the like) by using a PLC 10. The PLC 10 includes a main control unit 9, I/O units 19, 21 and 23 and a communication unit 17, which are all individually portable. The main control unit 9 is accommodated in a first control board 1 which is separated from the machine for industrial use. The I/O units 19, 21 and 23 and the communication unit 17 are installed in a second control board 3 which is different from the first control board 1. Then, the second control board 3 is arranged in a vacant space except the first control board 1, and the space is an exclusive space for the production facilities 100 in a plant.
