What is DCS system?

What is DCS System? A distributed control system (DCS) is a specially designed automated control system that consists of geographically distributed control elements over the plant or control area.

What are the different kinds of signals used in distributedcontrol systems (DCS)?

1. 1 Followingare the differentkindsof signalsusedin the DistributedControl Systems (DCS) 1) AI – AnalogInputSignal. 2) AO – AnalogOutputSignal. 3) DI – Digital InputSignal. 4) DO – Digital OutputSignal. 5) RTD Signals – Resistance Thermal Detector. 6) TC – ThermoCouple signals.

What are the attributes of DCS?

These attributes of DCS can be observed in its architecture shown in the diagram below. The basic elements comprised in a DCS include engineering workstation, operating station or HMI, process control unit or local control unit, smart devices, and communication system. It is the supervisory controller over the entire distributed control system.

What is the difference between DCS and centralized control system?

It differs from the centralized control system wherein a single controller at central location handles the control function, but in DCS each process element or machine or group of machines is controlled by a dedicated controller.
