Re: [foxboro] AIN Block / Deadband

Depending on your application you may want to take a look at the
DGAP block. We use these for tank level and temp control.

Subject:    [foxboro] AIN Block / Deadband


Based on the output from an AIN block, I am turning on/off equipment.  The
value from the AIN block sometimes lies right near the threshold for
turning
on/off the equipment.  The result is that the value from the AIN block
"bounces" above and below the threshold causing the equipment to turn on
and
off rapidly.  Looking at the AIN block documentation, they have a deadband
category (DELT01), BUT the documentation suggests that it is not
functional.


Does anyone have a simple way to send the output of the AIN block through a
deadband feature?
