Abstract

PURPOSE:To smooth the display increase and decrease of a display device in set- value changing operation without increasing a transmission-reception speed specially, by providing a subordinate controller with a main memory stored with received value and a subordinate memory stored with values used when set values are changed. CONSTITUTION:Transmission circuit L1 and L2 performing periodical transmission and reception connect main equipment ME to subordinate equipment SE, a set value set by subordinate equipment SE is received by main equipment ME and then transmitted to subordinate equipment SE to display the set value of subordinate equipment SE on the basis of the received signal. This subordinate equipment SE is equipped with main memory MM stored with received values and subordinate memory SM stored with values used when the set values are changed; when subordinate equipment SE changes the set values, the contents of memory SM are displayed on display device DP and also sent to main memory ME to display the contents of main memory MM not less than one period of periodical transmission and reception after the completion of the changing operation, thereby smoothing the display increase and decrease of display device DP.
