Is there a way to make an alarm happen if I have a value that rises more than, lets say 10, in 5 seconds? Example, chilled water value is 65 degrees and if it rises to 75 degrees within 5 seconds it triggers an alarm. ---

You'd need to take the derivative of that signal, then put bounds on the derivative. Taking a derivative requires doing math with prior values. Just using `previousValue` and `currentValue` on a change event is an option, but tends to be jittery for most purposes. I tend to use the `recorder()` function from my Integration Toolkit to have a well-defined, not quite short, sliding sample window in memory. And use first and last entries for the math, to have less jitter. ---

Thanks, I will see what I can do. Thats a good idea. I take it the recorder() function isnt something I have access to? ---

Install my Integration Toolkit module. It's free. Has lots of stuff that's generally useful. ---

Yeah, I changed the name from Simulation Aids after ICC this year, by popular demand.
