9.6 Field Communicator 375/475 (FC 375/475)

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.

9.6.1 Installation

The HART

®

Device Description for the signal converter 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.

9.6.2 Operation

Operating the signal converter via the Field Communicator is very similar to manual device
control using the keyboard.

The online help for each parameter contains its function number as a reference to the local
device display.

Parameter protection for custody transfer and the service menu is the same as on the device's
local display. Other specific protective functions such as the passwords for the quick setup menu
and the setup menu are not supported with HART

®

.

The Field Communicator always saves a complete configuration for the exchange with AMS, see
Appendix A. However, in the offline configuration and when sending to the device, the Field
Communicator only takes into account a partial parameter set (like the standard configuration of
the old HART

®

Communicator 275).

9.6.3 Parameter for the basic configuration

In online mode, counter measurements and the diagnosis value can be set using special
methods, see Appendix A. In offline mode, these parameters are read-only. However, when
transferring the offline configuration, this data is also written to the device.

INFORMATION!
For more detailed information see Appendix A, Menu tree for Basic DD.
