The International Society of Automation also produces the ISA-62443 standards as part of the information security standards. The security of private industries and governmental installations are often dependent on the reliable functioning of an Industrial control system.
A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines.
The device has two antennas. One antenna collects data from the sensors, and the other antenna forwards the data to the electrical utility control center over cell phone service. In some systems, powerline sensors may transmit information on the high voltage conductor itself rather than by transmission of a radio signal. [4] [5]
Control methods employ sensors to measure the output variable of the device and provide feedback to the controller so that it can make corrections toward desired performance. Automatic control manages a device without the need of human inputs for correction, such as cruise control for regulating a car's speed. Control systems engineering ...
As of 2016, other real-world applications include incorporating smart LEDs to direct shoppers to empty parking spaces or highlight shifting traffic patterns, using sensors on water purifiers to alert managers via computer or smartphone when to replace parts, attaching RFID tags to safety gear to track personnel and ensure their safety ...
Digital control systems to automate process controls, operator tools and service information systems to optimize plant safety and security are within the purview of the IIoT. [85] IoT can also be applied to asset management via predictive maintenance, statistical evaluation, and measurements to maximize reliability. [86]

An industrial control system (ICS) is an electronic control system and associated instrumentation used for industrial process control. Control systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems (DCSs) with many thousands of field connections.
