Abstract

Redundancy and fault tolerance are two of the most important considerations in automation control systems, as they provide stability and reliability for the whole system. This paper presents the types of redundancy that can be found in a Programmable Logic Controller (PLC) system at component-level, connection-level, and system-level, and is a review of various techniques and implementations of PLC redundancy, accompanied by a summary of redundancy options offered by PLC manufacturers in the global market.
