Industrial control system is a collective term used to describe different types of control systems and related instruments, including equipment, systems, networks, and controls used to operate and automate industrial processes. The functions of each industrial automation system vary from industry to industry, and are designed to efficiently process tasks electronically. This article will mainly introduce what industrial automation control systems are.
The rapid development of industrial automation control systems requires tighter integration between equipment on the factory floor and other parts of the enterprise. This integration requires a secure network infrastructure, smart devices that collect data efficiently, and the ability to convert data into actionable information.
Industrial control system is an important part of automation system. Various types of closed-loop control techniques ensure that process variables follow set points. In addition to this basic function, industrial automation systems also use different other functions, such as calculating the set point of the control system, starting or shutting down the factory, monitoring system performance, and equipment scheduling. Industry allows flexible, efficient and reliable production systems.
What are the industrial automation control systems
Distributed Control System (DCS): Although the term DCS is usually applied to any system where the controller is distributed rather than centralized, in the power generation and petrochemical process industries, it refers to a specific type of control system that can perform high-speed Complex simulation process control algorithm, and provide routine monitoring, reporting and data recording functions. In most applications, the input and output modules of the automation control system are distributed throughout the facility, but the control processor itself is located near the center of the control room. These systems usually use proprietary hardware, software, and communication protocols, and require replacement parts and technical support from the original supplier.

Remote terminal unit (RTU) is an RTU-based system that is very common in the power, natural gas, and water supply industries because they need to span long geographic distances to monitor and monitor. In the remote terminal, it is mainly to provide monitoring and control capabilities at unattended sites such as substations, metering stations, pumping stations and water towers. They communicate with the central station via telephone lines, optical fiber, radio or microwave transmission. The monitored sites are often relatively small, and RTUs are usually mainly used for monitoring and limited control. The hardware and software are proprietary, using proprietary or open protocols to transmit data to the central station.
Programmable controller (PLC) system: PLC can be networked, realize data sharing, and provide centralized monitoring functions. In the industry, control systems composed of networked PLCs are replacing factory DCS and RTU-based systems. They were developed for factory automation. They are traditionally good at high-speed discrete control, but now they also provide analog control capabilities. The hardware of the industrial automation control system is proprietary, but the control software and network communication protocol are open, allowing the system configuration, programming and technical support of a specific manufacturer's equipment to be obtained from many sources.
Monitoring and Data Acquisition (SCADA): The general name of a computerized system that can collect and process data and apply remote operation control. Typical uses include power transmission and distribution and pipeline systems. In response to the unique communication challenges (e.g., latency, data integrity) brought by the various media that must be used (e.g., telephone lines, microwaves, and satellites). It is usually shared rather than dedicated.
A remote terminal unit (RTU) is a microprocessor-based electronic device used to connect different hardware devices to a distributed control system. The remote terminal unit is also called a telemetry remote unit or a remote control remote unit. RTU transfers sensor data from the input stream in the control loop to the output stream for transmission to the ICS centralized command.

The industrial automation control system solution touches the security infrastructure, enables information to be transmitted and communicated, and is used for information collection. Sensors on mechanical equipment can usually achieve this. Industrial automation control systems also involve hardware, software, and communication alternatives that convert sensor information into information
