Configure Hart/Bell 202 Communications - Emerson Micro Motion SGM Series Configuration And Use Manual

Integrate the meter with the control system
Overview
An enhanced event is used to provide notification of process changes. 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.

Configure HART/Bell 202 communications

HART/Bell 202 communications parameters support HART communications with the
transmitter's primary mA terminals over a HART/Bell 202 network.

Select the event that you want to configure.
Specify Event Type.
Option 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.
OUT x ≤ A or x ≥ B
The event occurs when the value of the assigned process variable (x) is
out of range, that is, less than Setpoint A or greater than Setpoint B, end-
points included.
Assign a process variable to the event.
Set values for the required setpoints.
• For HI and LO events, set Setpoint A.
• For IN and OUT events, set Setpoint A and Setpoint B.
(Optional) Configure a discrete output to switch states in response to the event
status.
