Eliminating Single Points of Failure with Controls Redundancy

Eliminating Single Points of Failure with Controls Redundancy

What owners should know about high availability systems and redundancy.

About the Webinar

Most don’t understand the cost of downtime until they experience it for the first time. By then, the amount of money lost would more than have paid for the cost of a redundant system. But at that point, it’s too late and owners end up paying more to upgrade the system than the original cost.

When designing a high availability system, we strive to eliminate single points of failure. If you have a single PLC, there should be a mechanism by which processes and equipment will continue to operate even if the primary controller fails. But it’s not just about redundancy in PLCs. We take a holistic approach to redundant architecture. For example, if you have a critical instrument that would negatively affect your process should it fail, that’s another piece to the redundant systems puzzle.

Ultimately, a deep understanding of your own uptime goals and requirements is the best way to determine which level of availability or redundancy makes sense for you.


You’ll Learn

Debunked myths about hot redundancy, the levels of redundancy, which facilities need redundancy, the cost of redundancy (and is it worth it?), and what availability level of redundancy makes the most sense for your facility.
