PROBLEM TO BE SOLVED: To reduce a load on a controller by distributing control for each controlled device. SOLUTION: A control system has the plurality of controlled devices 4, a plurality of sub-controllers 3 and a main controller 4. The main controller 2 has a control program execution control table 23 for storing the main controller 2 and the sub-controller 3 which execute a control program, for every control program, transmits the designated control program for each sub-controller stored in the control program execution control table and transmits an execution instruction. Each sub-controller 3 writes the control program transmitted from the main controller 2 into a control program memory 21 of its own and executes the control program. COPYRIGHT: (C)2004,JPO
