Automation or automatic control, is the use of various control systems for operating equipment such as machinery, processes in factories, boilers and heat treating ovens, switching in telephone networks, steering and stabilization of ships, aircraft and other applications with minimal or reduced human intervention. Some processes have been completely automated.

PLC

SCADA SYSTEM

DCS

A programmable logic controller (PLC) is a special purpose computer aimed at implementing control solutions.

Historically PLC’s have been used mainly for on-off or logic type applications.

However, modern PLC’s have become increasingly

sophisticated and can now cover quite complex control tasks.

Funtions of PLC◦ Time Delay Relays

◦ Counter Relays

◦ Special Functions

◦ User Defined Functions

◦ Special Bits

A SCADA system performs four functions:

1. Data acquisition

2. Networked data communication

3. Data presentation

4. Control These functions are performed by four kinds of SCADA components:

1. Sensors (either digital or analogue) and control relays that directly interface with the managed system.

2. Remote telemetry units (RTUs). These are small computerized units deployed in the field at specific sites and locations. RTUs serve as local collection points for gathering reports from sensors and delivering commands to control relays.

3. SCADA master units. These are larger computer consoles that serve as the central processor for the SCADA system. Master units provide a human interface to the system and automatically regulate the managed system in response to sensor inputs.

4. The communications network that connects the SCADA master unit to the RTUs in the field.

The reality with wired solutions◦ Long distances from critical monitoring

◦ Large obstructions can make wiring impractical or impossible

◦ Processes or equipment need monitoring in use

◦ No power available in remote applications

◦ Expense

What is industrial wireless?◦ Transmitting information via radio Transmitters Receivers Gateways

◦ Monitoring solution Tank levels monitors Motor operated valves Pumps Heat trace

◦ No need for wires or cable ◦ Radios are programmable Multiple radios on a reliable path To send data upon

Request Periodically Pre-determined signal values

Applications considerations

◦ Control

• Requirements

• Process control

• Automated and manual process control for various

industries

• Alarms

• Monitor conditions and automate alarms when needed

Chalenges indeed cost of automation product ◦ Highly complex◦ Not economical◦ Time delay to set up

ConclusionHighly advanced technologies which comprises of Automation and wireless communication help us to day to life in fully controlled environment.and Set up the revolutionary changes is communication .
