At one time, failure in a PLC-based system might take a single machine offline for a day, but that’s no longer true. PLC/PAC and edge controller systems today play an increasingly critical role in most industrial applications, including key functions in data analysis and communications. PLC problems can significantly impact uptime and efficiency. While failures may be infrequent, any possibility greater than zero can be unacceptable.
At the same time, building redundancy and high availability into PLC and edge controller systems isn’t traditional due to issues of complexity and cost. But, as this new white paper – “High Availability for the Price of a Spare” – tells you, this is no longer true. The democratization of redundancy has arrived thanks to a new patented technology. Modern PLC/PACs and edge controllers, such as the Emerson PACSystems RX3i controller, provide a solution so two controllers can support the same system, running in parallel, fully synchronized, and locked together in real time with access to the same I/O.
There’s lots to learn about the barriers that have prevented PLC-based systems from being made redundant, and how new technology can make literally every PLC and edge controller application high availability, easily and cost-effectively.
