Ramp Time Niagara Wiresheet

[numbawunfela]

I am being compelled to program a piece of equipment in Niagara Wiresheet logic with NRIO.
I am in need of a way to take a varying analog output and apply a specific ramp time to it. So if I have a 100% command, and that instantly drops to 0 - I can run that instant drop through a block that will bring it down to 0 slowly over a specific time period (like 2 minutes - adjustable).
Distech has this in their palette, but I am not seeing anything like that in Niagara. But maybe I am not looking that closely.

Thanks in advance guys.

I got it with a Numeric Delay - just had to play with the settings to get the period right.
nevermind...

Ok, Not minding. That was going to be my suggestion anyway.

No problem (and no help either I might add). The Numeric Delay also works well in Duct Static Reset and DA Setpoint reset if you ever have to do that.

I recently used it on a chiller plant I programmed. The new chiller plant is in a craphole building where none of the air handler controls work, so multiple times a day they are changing the chilled water set point. It's warm, they set it to 43, 2 hours later it's cold, they set it to 57 degrees, all day and night since it's a hospital. It was causing some nuisance trips on the chillers. So I used a numeric delay on the chilled water set point. They can change it all they want, but now the set point only moves 1 degree every 10 minutes. Lol. No more service calls now.

I love hearing stories like this. Makes me feel validated our team isn’t the only one being asked to deal with these types of issues.
