8.4 Inputs/outputs and HART
®
dynamic variables and device variables
Code = device variable code
The HART
®
dynamic variable PV can be switched between conductivity and resistivity. If the PV is
mapped to conductivity, the SV is mapped to resistivity and vice versa.
8.5 Field Communicator 475 (FC 475)
The Field Communicator is a hand terminal from Emerson Process Management that is
designed to configure HART
®
and Foundation Fieldbus devices. Device Descriptions (DDs) are
used to integrate different devices into the Field Communicator.
8.5.1 Installation
The HART
®
Device Description for the sensor must be installed on the Field Communicator.
Otherwise only the functions of a generic DD are available to the user and the entire device
control is not possible. A "Field Communicator Easy Upgrade Programming Utility" is required to
install the DDs on the Field Communicator.
The Field Communicator must be equipped with a system card with "Easy Upgrade Option". For
details consult the Field Communicator User
’
s Manual.
