Server Redundancy Overview

Simply enabling server redundancy for your project provides you with a wealth of redundancy features. However, server redundancy is only a part of your system. The other key parts of your system are your Project, PLCs and the communications network. Combined together these pieces form a mission critical application. Therefore, the application is only as robust as its weakest link. While server redundancy provides many built in features, it cannot repair a faulty network or fix incorrectly written logic. Server redundancy depends on you, the Control Engineer to build a robust environment to enable server redundancy to perform its job.

Review these topics for an overview of the decisions you need to make while designing your mission critical application:
  • Server redundancy hardware requirements
  • Server redundancy application requirements
  • Server redundancy configuration overview
  • Automatic redundancy operation overview
  • Manual redundancy overview
