Abstract

Standby redundancy for controllers is used to improve the availability of many manufacturing systems. The software redundancy features offered by typical programmable logic controllers (PLCs) are reviewed. An equivalent Erlang-based standby redundancy solution is presented in this paper. Erlang is a functional programming language designed for the development of fault-tolerant soft real-time control systems. The Erlang software redundancy solution employs various features in Erlang (and its associated library, OTP) that greatly simplify achieving standby redundancy. This paper describes an Erlang and OTP approach that facilitates implementing standby controller redundancy at a software level for devices which do not provide such mechanisms at a hardware level, similar to that provided by typical PLCs.
