PROBLEM TO BE SOLVED: To provide a control system, in which when a control device having a new function is added to an existing control system, detection information of a sensor already installed to the control system can be easily used without newly adding a sensor. SOLUTION: The control system comprises a first controller 11, a second controller 12 and a sensor 13. The first controller 11 comprises a control part 14 for controlling based on information of the sensor 13 or the like, and a conversion circuit 15 for inputting an output signal outputted from the sensor 13 and converting the input signal to a signal readable by the control part 14. The conversion circuit 15 comprises an output part 16 for outputting the converted signal to the control part 14, and an external output part 17 capable of connecting with an external wire. The second controller 12 comprises an input part 19 connected to the external output part 17 of the conversion circuit 15 through the external wire 18, and a control part 20 using the signal of the sensor 13 inputted from the input part 19.
