Cyclical Redundancy Check
Knowledge Base

Automation Media's recommended most important key terminologies you need to know if you work in Automation, Controls, Brilliant Manufacturing, Operational & Industrial Intelligence or IoT etc. ; regardless of any vendor(s) you are dealing (Allen Bradley, GE Fanuc, Siemens, Modicon, Mitsubishi, Omron, Automation Direct etc).

Cyclical Redundancy Check (CRC) is a procedure used to check for errors in data transmission.

The CRC was invented by W. Wesley Peterson, and published in his 1961 paper.

A cyclic redundancy check (CRC) is a type of function that takes as input a data stream of any length and produces as output a value of a certain fixed size.

The term CRC is often used to denote either the function or the function's output.

A CRC can be used in the same way as a checksum to detect accidental alteration of data during transmission or storage.

CRCs are popular because they are simple to implement in binary hardware, are easy to analyze mathematically, and are particularly good at detecting common errors caused by noise in transmission channels.
