This control system is provided with a controller, a controller which is a loopback communication device, a first communication route, and a second communication route. The controller generates and transmits control frames to slave devices. The controller performs loopback communication of the control frames. In the first communication route, multiple slave devices are connected between the controller and the controller using communication cables. In the second communication route, the first controller and the second controller are connected over a communication cable.
