Background

In this Use Case, a condition was created to identify when a compressor is running.  Let's say I'd like to extend each capsule in this condition so that instead of ending when the compressor turns off, it ends when the next compressor running capsule starts.

Method

The method used depends on the Seeq version.

Seeq R21.0.42 and Later

Version R21.0.42 introduced the .growEnd() operator; this operator grows capsules in in a condition by extending the end until the start of the next capsule.

Earlier Versions (Before R21.0.42)

1. First, create a condition that is the inverse of the Compressor Running condition.  This can be achieved using the .inverse() function in Formula

2. Next, extend each Compressor Running capsule so that they overlap with the Downtime capsules.  This is achieved using the .move() function in Formula.

3. Finally, combine the Downtime and Compressor Running - Extended conditions use the union logic in the Composite Condition tool.image.png
