2. Industrial control system - Wikipedia

   en.wikipedia.org/wiki/Industrial_control_system

   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.

   IEC 62443 is a series of standards that address security for operational technology in automation and control systems. The series is divided into different sections and describes both technical and process-related aspects of automation and control systems security.

5. SCADA - Wikipedia

   en.wikipedia.org/wiki/SCADA

   A programmable automation controller (PAC) is a compact controller that combines the features and capabilities of a PC-based control system with that of a typical PLC. PACs are deployed in SCADA systems to provide RTU and PLC functions.

   The system diagram for representing control loops is a Piping and instrumentation diagram. Commonly used control systems include programmable logic controller (PLC), Distributed Control System (DCS) or SCADA. Example of level control system of a continuous stirred-tank reactor. The flow control into the tank would be cascaded off the level control.

7. Automation - Wikipedia

   en.wikipedia.org/wiki/Automation

   Steam engines promoted automation through the need to control engine speed and power.. The introduction of prime movers, or self-driven machines advanced grain mills, furnaces, boilers, and the steam engine created a new requirement for automatic control systems including temperature regulators (invented in 1624; see Cornelius Drebbel), pressure regulators (1681), float regulators (1700) and ...
