Abstract

PURPOSE:To prevent malfunction due to disturbance, a power failure, etc., by providing a slave-station device, having a microprocessor, with a nonvolatile read/ write memory and by cyclically transferring plant data from a master-station device into the memory. CONSTITUTION:In a master-station unit 1 at a control spot required plant data are added in set word 4, which is cyclically sent as transmitted data to slave-station device 2-1-2-n at controlled spots at any time together with synchronizing word 3 and selective control word 5. Slave-station device 2-1-2-n receive the data and check errors, so that the data when found correct will be written in nonvolatile read/write memories. Therefore, data are rewritable at any time, erroneous writing operation due to disturbance, noises, etc., can be prevented and even in a power failure, data are retained.
