Abstract
PURPOSE:To omit the encoder and the decoder to attain a low cost as well as increase the reliability, by composing the word by arranging the unit information which can be expressed with one bit in the prescribed order of the plural units. CONSTITUTION:The information of each relay of relay contact group 51 in the remote control monitor device depends on the fact that the relay is under the off state (e.g. in correspondence to ''0'') or the on state (e.g. in correspondence to ''1''). And the relay information can be expressed by the binary code of one bit. For instance, if the number of the relays of group 51 is 8, the state of group 51 is transmitted 11 by the 8 bits of 1-8 of word composition 50 to secure display 60. Of course, in that case, both the decoder and the encoder which are used so far can be omitted. And instead of these units, control signal recognizing circuit 23 constituted by connecting vertically OR gate 22, AND gate and T-type FF each plus slave station calling push-button switch 24 are added newly.
