Abstract

PURPOSE:To shorten the wiring length of a transmission line, by constituting a device to exchange a data as a parallel signal between the coupling terminal devices which are provided respectively on the transmission line of a multiple control system CONSTITUTION:While each terminal unit is being polled in order through the transmission line 2A from the master equipment of the multiple control system A, the coupling terminal unit 5A is polled. A control signal from the master equipment is input to the terminal unit 5A from its SIG terminal, it is converted from series to parallel, and it is output as a parallel signal from the output terminals OUT 1-5. This signal is input to the input terminals IN 1-5 of the coupling terminal unit 5B through the photocoupler PC1. This data is stored once in the inside of the terminal unit 5B, and when it is polled through the transmission line 2B from the master equipment of the multiple control system B, a data stored in the terminal unit 5B is transmitted to the master equipment of the system B. At this time, in case when there is a data to be transferred from the system A to B, it is transmitted through the terminal unit 5B, the photocoupler PC2, and the terminal unit 5A.
