dampening a G15 module analog input

Hi all.

Had a temp/humidity controller go toes up at work today and no spare. However in out panel we have a red Lion g15 HMI with a couple of modules plugged in. One being a analog unit and our temp and humidity sensors feed it using 4-20ma.

So did a quick program and drove a couple of outputs to control steam and heat relays.

however the input dances all over the place and I was wondering if anyone has a suggestion on how to dampen it a bit? I thought about using an array of tags and simply averaging say 10 tags but maybe there is already something there I dont know about.

Its a quick and dirty fix for now and a longer term solution will need to be sort but lets see if tonights production gets through

Using a filter?

You could always use a simple first order filter to receive a bit more consistent values.

If you prefer something more complicated I would look at Kalman filter but I'm not sure it's worth the trouble!
