より構成されている。As shown in FIGS. 4 and 5, a conventional dependent station determines whether or not the transmission address is its own station with respect to communication data including a transmission address received from the control station 201 via the control station communication line, In the case of the own station, the control station communication unit 205 reads or writes the internal data 207, and the control station communication unit 205 reads or writes the internal data 207, and writes the data received from the previous dependent station 202 via the dependent station communication line to the internal data 207, and the internal data 2070 of the next stage. It is composed of a dependent station communication section 206 that performs transmission to the dependent station 204.
通信制御装置としての従属局は、制御局との通信と他の
従属局相互間との通信が一般には非同期に発生するため
、この2つの通信を制御局通信部と従属局通信部に分け
て行なっている。In a dependent station as a communication control device, communication with the control station and communication with other dependent stations generally occur asynchronously, so these two types of communication are divided into a control station communication section and a dependent station communication section. I am doing it.
このため、すべての従属局に制御局通信用の回線と、従

う欠点がある。Therefore, there is a drawback that two lines, one for control station communication and the other for dependent station communication, must be connected to all dependent stations.
