<p>PURPOSE:To secure balance between multiplexed control systems mutually by reading out the internal data of each control system for the same input signal of a device out of the internal data saved by a memory means, selecting specific data out of them, and outputting the data as the output operating signal of its own control system. CONSTITUTION:Input data, integration data, and the data of an arithmetic gain, etc., required for a control and arithmetic at every control system are inputted to a signal selection circuit 11 in the control system having a memory function and a transmission function at the time of inputting or generating the data, and they are saved in the memory means 13 in the signal selection circuit, and simultaneously, they are transmitted to another control system. Furthermore, the data transmitted from another control system is received, and is saved in memories 17-19. Next, the data in its own control system and another control system are read out from each memory to execute the control and arithmetic, and the control and arithmetic is performed by using selected data after comparison and selection. Thereby, it follows that the same control and arithmetic can be performed in each control system with the same data, which secures the identity of the output of each control system.</p> |
