This document outlines the steps necessary to set up a redundant system using the CODESYS Redundancy Addon with two WAGO controllers (in this case, two 750-8212 PFC200s). It shows the steps to configure two controllers to communicate over the redundant link, synchronize the PLC scans, and share redundant data. At the end of the document, it shows an example program that demonstrates the use of Modbus/TCP as the redundant protocol for communication with a fieldbus coupler.
