摘要:
Safety units 1d to 1f for executing a safety function processing are connected to a non-safety controller constituted by connectting a plurality of units 1b, 1c including CPU units 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.
