Introduction
This section details the HART Device Variables and how to assign them to Dynamic
Variables (PV, SV, TV, & QV). Figure 4-1 illustrates a typical connection setup. Refer to
Section 2 for more details on the SITRANS F US Clamp-on Communication Module.
The SITRANS F US Clamp-on Communications Module, in addition to providing various
communication protocols, including BACnet, Modbus, EIP & N2, also includes a HART 4-20
mA output that is always active regardless of other protocols selected. This document details
the HART Device Variables and how to assign them to Dynamic Variables (PV, SV, TV and
QV). The figure below illustrates a typical connection setup.
