Industrial Control System: Type and Benefits

Team 13SQFT POSTED BY Team 13SQFT

The phrase "Industrial Control System" (ICS) refers to a combination of many types of control systems and related instrumentation, devices, systems, networks, and controls needed to operate and automate industrial processes.

Depending on the sector, each ICS operates differently and is intended for executing jobs effectively through electronic operations. The devices and protocols utilised in an ICS are today employed in practically every industrial sector and vital infrastructure, including manufacturing, transportation, power, and water treatment.

Types of Industrial Control Systems

Some of the common types of Industrial Control Systems are Distributed Control Systems (DCS), Remote Terminal Units (RTU) and Programmable Logic Controllers (PLC).

Distributed Control Systems:

An industrial control system that is installed and controlled in a distributed fashion, allowing individual control of numerous dispersed control systems or processes. A control system refers to control obtained through intelligence spread throughout the process to be controlled rather than by a single unit positioned centrally.

Remote Terminal Units (RTUs):

A remote terminal unit (RTU) is a microprocessor-based electronic device used in industrial control systems (ICS) to link various devices to distributed control systems (DCS) or supervisory control and data acquisition (SCADA). Remote units of telemetry and remote units of virtual control are other names for RTUs. RTUs route sensor data from control loop input streams to an output stream for transmission to ICS centralised command.

Programmable Logic Controllers (PLCs):

Programmable logic controller (PLC) based systems: PLCs can be networked together to share data as well as give centralized monitoring and control capability.

In many sectors, control systems composed of networked PLCs are replacing both plant DCS and RTU-based systems. They were designed for factory automation and have historically excelled in high-speed discrete control, but now offer analogue control capability as well.

Benefits of Industrial Control System

Increased Health and Safety

Health and safety are the key benefits of industrial control systems in general, including SCADA. Understanding the environment in which workers are being deployed can offer you a crucial edge in keeping them safe.

Minimization of threat or exposure

The capacity to regulate and reduce harm or exposure due to failures or malfunctions are the second biggest advantage of an efficient industrial control system.

When a power line fails, an industrial control system or SCADA system can detect, monitor and notify Control that a pole has failed or a line is contacting the ground. Workers can not only be alerted of this, but the fault region may also be remotely isolated and switched off to safeguard those around. This involves both workers and the general public.

Protection of Assets

The third advantage is asset protection. Assets can be safeguarded by prevention.

Some transformers are multimillion-dollar investments that may be safeguarded by avoiding an overvoltage state. Understanding the overvoltage exposure of a transformer allows you to obtain the same equivalent life cycle out of the asset by controlling load or lowering the load threshold if it has witnessed overvoltage several times.

The primary objective of all industrial control systems is to protect assets and maximise asset life.
