Setup Lists
You will not see every parameter listed here. These vary depending on the features enabled on your device.
Hysteresis
Set the hysteresis for the limit function. This
determines how far into the safe range the
process value must move before the limit can
be cleared.

12004
Low Limit Set Point *
Set the low process value that will trigger the
limit.

Limit Status *
Reflects whether or not the limit is in a safe
or failed mode.
Fail (32)
Safe (1667)

Integrate with System In a limit state the controller will turn off the
outputs, terminate an active profile and freeze
PID and TRU-TUNE+® calculations.
