Custom Variables for Time Based Evaluations

There are times when an evaluation of an expression should only be true after a certain amount of time.  In order to accomplish this a custom variable can be used to track the amount of time a particular expression has been true.

A Custom Variable can be created and then the Custom Variable Value and Custom Variable Time PCSDB variables can be used to track how long a particular scenario has been true. 

Here are a few examples of how this can be used:

Ignore short cycle stops due to tool changes

End a downtime if the equipment is in cycle
