4. Set a value for the setpoint ( Setpoint A ).
5. (Optional) Configure a discrete output to switch states according to event status.

An “enhanced” event is used to perform specific transmitter actions if the event occurs. An enhanced
event occurs (is ON) if the real-time value of a user-specified process variable moves above (HI)
or below (LO) a user-defined setpoint, or in range (IN) or out of range (OUT) with respect to two
user-defined setpoints. You can define up to five enhanced events. For each enhanced event, you can
assign one or more actions that the transmitter will perform if the enhanced event occurs.
Procedure
1. Select Event 1 , Event 2 , Event 3 , Event 4 , or Event 5 from Event Name .
2. Specify Event Type .
HI The event will occur if the value of the assigned process variable ( x ) is
greater than the setpoint ( Setpoint A ), endpoint not included.
x > A
LO The event will occur if the value of the assigned process variable ( x ) is less
than the setpoint ( Setpoint A ), endpoint not included.
x < A
IN The event will occur if the value of the assigned process variable ( x ) is “in
range,” i.e., between Setpoint A and Setpoint B , endpoints included.
A ≤ x ≤ B
OUT The event will occur if the value of the assigned process variable ( x ) is “out of
range,” i.e., less than Setpoint A or greater than Setpoint B , endpoints included.
x ≤ A or x ≥ B
3. Assign a process variable to the event.
4. Set values for the required setpoints.
• For HI or LO events, set Setpoint A .
• For IN or OUT events, set Setpoint A and Setpoint B .
