PROBLEM TO BE SOLVED: To realize a control system for exchanging data between a plurality of control networks with a simpler configuration without increasing the number of devices mounted in the control system. SOLUTION: The control system comprises a plurality of control network interfaces 41a... for connecting devices as objects under control to a plurality of networks Na... respectively, and device controllers 32 for controlling the devices connected to the control networks Na.... The device controllers 32, based on control program network, execute operation suggested by instructions and data exchange between the plurality of the control networks by communicating with the devices suggested by operands of instructions included in the control programs through the networks to which the devices are connected and the control network interfaces connected to the control networks.
