6.1 Configure events
An event occurs when the real-time value of a user-specified process variable moves past a
user-defined setpoint. Events are used to provide notification of process changes or to
perform specific transmitter actions if a process change occurs.

Enhanced Events
Overview
An enhanced event is used to provide notification of process changes and, optionally, 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.
Procedure
1. Select the event that you want to configure.
2. Specify Event Type .
Options Description
HI x > A
The event occurs when the value of the assigned process variable ( x ) is
greater than the setpoint (
Setpoint A
), endpoint not included.
LO x < A
The event occurs when the value of the assigned process variable ( x ) is
less than the setpoint ( Setpoint A ), endpoint not included.
IN
A ≤ x ≤ B
The event occurs when the value of the assigned process variable ( x ) is in
range, that is, between Setpoint A and Setpoint B , endpoints included.
