connection

1. Connection between hardware devices

This kind of connection is carried out in the control room, most of which are multi-core shielded twisted pair or coaxial cables, and are plugged with standardized plug-ins.

These cables are called system cables and have a variety of types, so when working, it is necessary to be careful and cautious, not to plug them in incorrectly, and to do a good job of inspection.

2. Connection between DCS system and online instruments

This is the connection between the control room and on-site instruments, which has a large quantity and usually comes in two forms:

A cable is connected from the beginning to the bottom, that is, the two core cable of the on-site instrument or actuator is directly connected to the corresponding module wiring terminal of the DCS system in the control room;

The control room is connected to a centralized location on site through a multi-core main cable, and then connected to each on-site instrument or actuator through a junction box using two core cables.

Due to the large number of wiring points, each point is accurate and reliable, arranged neatly and aesthetically pleasing.

Power Supply

The DCS system has high requirements for power supply, which is reliable and reliable;

Usually using dual circuit power supply, automatic switching;

One or two circuits are all powered off, and there is also an uninterrupted power supply (UPS) that is momentarily connected to ensure that the system operates in a state.

DCS system configuration includes

Switch

Network printer,

Engineer Station,

Operator station,

Controller firewall,

Database server,

Serial server.

C300 controller

The specific configuration of operator stations, engineer stations, etc. may vary depending on the actual situation.
