## Abstract

A control module includes a first power-supply-signal connection portion for connection of a power supply signal with one adjacent control module and a second power-supply-signal connection portion for connection of the power supply signal with the other adjacent control module. In the same control module, the first power-supply-signal connection portion, the second power-supply-signal connection portion, and a power input portion in a monitoring-and-control processing unit are connected to each other.

## Claims

### Claim 1

A monitoring and control system comprising:
a control module group composed of a plurality of control modules which are connected to each other and each of which includes a monitoring-and-control processing unit that performs a process for monitoring and control of a monitoring control target;
a first adapter which is connected to the control module at one end of the control module group and to which a communication cable is connected; and
a second adapter which is connected to the control module at the other end of the control module group and to which a communication cable is connected,
wherein power is supplied through the communication cable using PoE,
wherein the first adapter includes a power separator that separates a power supply signal supplied through the communication cable,
wherein the second adapter includes a power combiner that combines the power supply signal with a control signal,
wherein each control module includes a first control-signal connection portion for connection of the control signal with one adjacent control module, a first power-supply-signal connection portion for connection of the power supply signal, a second control-signal connection portion for connection of the control signal with the other adjacent control module, and a second power-supply-signal connection portion for connection of the power supply signal,
wherein, in the same control module, the first control-signal connection portion is connected to the second control-signal connection portion,
wherein, in the same control module, the first power-supply-signal connection portion is connected to the second power-supply-signal connection portion,
wherein the first adapter includes a third control-signal connection portion for connection of the control signal with the control module that is connected and a fourth power-supply-signal connection portion for connection of the power supply signal,
wherein the second adapter includes a fifth control-signal connection portion for connection of the control signal with the control module that is connected and a sixth power-supply-signal connection portion for connection of the power supply signal, and
wherein, between different control module groups, the first adapter in one control module group is connected to the second adapter in an adjacent control module group via the communication cable to form a network.

### Claim 2 (depends on 1)

The monitoring and control system according to claim 1,
wherein the control module includes a power supply connection unit to which a power supply is connected, and
wherein, in the same control module, the power supply connection unit, the first power-supply-signal connection portion, and the second power-supply-signal connection portion are connected to each other.
