PROBLEM TO BE SOLVED: To provide a controller system in which a controller is accomplished under the state where a safety system and a non-safety system coexist satisfactorily, to provide a controller system in which portions that can be handled as a common processing between the safety system and the non-safety system are made in common with each other, while a safety function of the safety system can be guaranteed. SOLUTION: Safety units 1d-1f for performing a safety function processing are connected to a non-safety controller constituted by connecting a plurality of units 1b, 1c including a CPU unit 1a. A CPU bus 10 to be connected with the CPU units and a safety dedicated bus 11 for mutually connecting the safety units are provided to the safety units. Since the safety dedicated bus is isolated from the non-safety system, reliability of the safety function can be secured. The CPU unit can read out data through the CPU bus irrespective of the safety unit and the non-safety unit. COPYRIGHT: (C)2007,JPO&INPIT
