Abstract

PURPOSE:To simplify the circuit constitution, by reducing a transmission time interval of a control signal and fixing it, through the use of memory designation not used for ON/OFF control, in a remote monitoring and controlling device having a function of transmission of a set value. CONSTITUTION:The set value signal from an analog output circuit 5 and the signal of set item designation from the ON/OFF control signal output 7 are fed to slave station 3 via a connecting line LINE1 via a signal transmission circuit 12. At the slave station 3, the set value signal is output from a set value output circuit 18 and written in the analog memory 25 with the set value write-in instruction output from the ON/OFF control output circuit 19. The set value answer back signal 27 enters the measurement input circuit 23 and is transmitted to the master station 2. After confirming the content of the signal returned at the master station 2, the transmission is finished by turning off the set value signal and item designation signal. Thus, the transmission word is enough by using only one word.
