Claims

[Scope of utility model registration request]

In a remote monitoring and control device that monitors and controls multiple identical devices lined up on one line, the remote control master station, which consists of a code conversion circuit, a parallel-to-direct conversion circuit, and a transmission circuit, converts the control signal from the console into a code conversion circuit. A remote control slave station is provided with a device number code setting circuit, a starting point device number storage buffer, and an end point device number storage buffer, and is composed of a receiving circuit for receiving control signals from a master station, a serial-to-parallel conversion circuit, and a control signal output circuit. By providing a start point device number setting circuit and an end point device number setting circuit in the 'As'II8 signal output circuit,
A remote monitoring and control device characterized in that it is possible to control a plurality of the same devices by transmitting a control signal once.
