Large Plant Sees Numerous Improvements from Switch to Ignition3 min video / 2 minute read
The purpose of this project was to swap out the site’s previous SCADA system with Ignition. The site previously used 23 servers to run its SCADA system; the Ignition system now uses four. The site previously ran on Windows, but as a part of this upgrade the SCADA system (servers and clients) is exclusively running on Linux. This has provided a lot of flexibility to tailor the system architecture to the site’s needs.
The total licensing savings from this upgrade will result in a three-year ROI on the project.
There were a lot of improvements made to the SCADA system as a result of this project. The site previously stored 14,000 tags in history. After the installation of Ignition, 180,000 tags are being historized. This amounts to 80 million rows of history stored daily.
Every shape on the screen can be trended by right-clicking on it and selecting “add to trend.” All the HMI screens can be replayed using the Plant Replay module developed by Tamaki. Alarming and auditing information, though previously stored, was difficult to extract and interrogate before Ignition. Within weeks of the installation, production teams were tracking down and solving process issues with data that had been previously unavailable.
Now with Ignition, Southwest Cheese is using SQL databases to record externally measured process information that was previously unavailable to the control system. This has enabled real-time batch visualization, aggregated statistics, and relational measurements to production teams. Southwest Cheese is planning future projects to further integrate other disparate systems into one unified plant information system which will help simplify work done by the controls team and provide further savings by removing licensing costs of other applications.
Southwest Cheese is planning a $150 million expansion that will push the plant to process 15 million pounds of milk per day — and will use the current Ignition infrastructure in that expansion.
