Output Action. This is designed to make it easier to configure the transmitter for legacy behavior.
Always verify mA Output Action after setting HART Address.

The HART variables are a set of four variables predefined for HART use. The HART variables include the
Primary Variable (PV), Secondary Variable (SV), Tertiary Variable (TV), and Quaternary Variable (QV). You can
assign specific process variables to the HART variables, and then use standard HART methods to read or
broadcast the assigned process data.
Note
The Tertiary Variable and Quaternary Variable are also called the Third Variable (TV) and Fourth Variable (FV).
Restriction
The Primary Variable is always the process variable assigned to mA Output 1. If you change either of these
assignments, the other is changed automatically.
The Secondary Variable and Tertiary Variable are not tied to any outputs. This is different from previous
Micro Motion Coriolis transmitters.
Procedure
Assign variables to the PV, SV, TV, and QV as desired.
