Britannia PLC Software Migration

In addition to upgrading the HMI on the Britannia Platform, ICS Triplex/Rockwell Automation also had the task of upgrading the underlying safety-critical systems.

The original system consisted of LM90-70 PLCs, which were to be replaced with RX7i PLCs. Rather than manually port the software from one platform to the other, it was decided to perform the conversion automatically, and to create a tool that would validate the conversion. This would allow the manual conversion work to be confined to a limited number of issues.

We were brought in to devise the test procedures for the tool, and to perform testing on the tool.
