Setting Segment Tolerance

Use this menu to set a positive or negative tolerance value for each
segment. this value is displayed in the engineering units of the process
and is a deviation from the setpoint.

Tolerance works as shown in this diagram:

If you enter a positive tolerance, the process is out of tolerance when the
PV goes above the setpoint plus the tolerance.

If you enter a negative tolerance, the process goes out of tolerance when
the PV goes below the setpoint minus the tolerance.

Selectable Values: -99 to 99, or Off (no tolerance).

Ending a Profile

Use this menu to make a segment the last one in the profile.

Selectable Values: No or Yes.

Repeating a Profile

Use this menu to set the number of times you want a profile to repeat or
cycle.
