Abstract

PURPOSE:To shorten transmission time and processing time necessary for equipment to be controlled by transmitting control signals from the master station to a slave station regarding the plural equipments on the slave station collectively and simultaneously, and storing the signals on the slave station side. CONSTITUTION:The master station 2 transmits the plural control signals of the plural equipments to be controlled collectively and simultaneously to the slave station 3 through a transmission line 4. The slave station 3 stores the contents of the plural control signals, and executes the control of the equipments to be controlled based on thus stored control signals. With such a constitution as the above, the master station 2 can reduce the number of times of transmission necessary for n-pieces of equipments to be controlled down to 1/n. Meanwhile, on the slave station 3, the plural equipments can be controlled independtly without exchange control signals from the master station 2 at the time of each control, as a result, the control time necessary for the equipments can be shortened.
