This is a list of all Internet Relay Chat commands from RFC 1459, RFC 2812, and extensions added to major IRC daemons. Most IRC clients require commands to be preceded by a slash ("/"). Some commands are actually sent to IRC bots; these are treated by the IRC protocol as ordinary messages, not as /-commands.
Early semi-mechanical installations with common control components existed, for example rotary systems in Sweden and France in 1915, and the first panel switches in Newark, New Jersey, also in 1915. The first large-scale, fully automatic, common control switching system deployed in commercial production service was the ATlantic central office ...
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.
The Internal Revenue Code of 1986 (IRC), is the domestic portion of federal statutory tax law in the United States. It is codified in statute as Title 26 of the United States Code . [ 1 ] The IRC is organized topically into subtitles and sections, covering federal income tax in the United States , payroll taxes , estate taxes , gift taxes , and ...
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.

A control loop is the fundamental building block of control systems in general and industrial control systems in particular. It consists of the process sensor, the controller function, and the final control element (FCE) which controls the process necessary to automatically adjust the value of a measured process variable (PV) to equal the value of a desired set-point (SP).
The definition of a closed loop control system according to the British Standards Institution is "a control system possessing monitoring feedback, the deviation signal formed as a result of this feedback being used to control the action of a final control element in such a way as to tend to reduce the deviation to zero."
