A recent article in CONTROL magazine tells how engineers at Air Liquide now have a standard way to connect the company’s air separation units. These units need to work with a variety of distributed control systems in a number of locations. The challenge was to build a system flexible enough to connect to the different control systems without having to reconfigure each of them.
Using the Bridging interface in Skkynet’s DataHub industrial middleware, along with a custom DataHub script created in collaboration with Software Toolbox, Air Liquide has successfully installed their first system, and now plans to expand to more locations in a standard way.
“When Air Liquide shared their requirements with us, the DataHub came immediately to mind as the easiest and most reliable approach,” said Win Worrall of Software Toolbox, who worked closely with the engineering team.
