DEADBAND DIGITAL

Dear All

 

I have a user who has a digital tag that indicates the cool down of a bit of equipment...he wants us to stop it flicking up and down between states when it is hovering around the changeover point from one state to another like 230deg then 225deg and the digi changes state, then back up to 230 again then down to 229 and it changes state again.

 

 

 

what is the best way to introduce a deadband to smooth it out so he doesnt get a bunch of alarms??? exception setting, filtercode?

 

all contributions welcome...
