CONNECTING TO A
DEVICE
Use the provided lead set and the HART or Fieldbus (if licensed)
Applications to connect and communicate with a device. The
appropriate device description is also required. If the 475 Field
Communicator does not have the HART device description, the device
can be displayed in forward compatibility mode. This mode uses a
generic device description and does not display all device functionality.
Three terminals for the lead set are on the top of the 475 Field
Communicator. Each red terminal is a positive connection for its
protocol, while the black terminal is a common terminal shared by both
protocols. An access door ensures only one pair of terminals is
exposed at any one time. Several markings indicate which pair of
terminals is for which protocol.
See "Section 3 HART functionality" and "Section 4 Fieldbus
functionality" for wiring diagrams and more information. Appendix B
displays diagrams for Intrinsically Safe installations.
PC APPLICATIONS Connect your 475 Field Communicator to a supported PC application,
such as AMS
Suite: Intelligent Device Manager or the Field
Communicator Easy Upgrade Utility, to download new system
software, device descriptions, and licenses. You can also transfer
HART configuration files, Event Capture files, and ScratchPad (.txt)
files to a PC.
AMS Device Manager The 475 Field Communicator can connect to AMS Device Manager
(version 6.2 or higher), letting you create, open, edit, or compare
HART device or user configuration files. You may need to connect
using IrDA if Bluetooth is not supported in your version. You can also
transfer configurations between AMS Device Manager and a storage
location in the 475 Field Communicator. Check the AMS Device
Manager Books Online for more information.
Field Communicator Easy
Upgrade Utility
The 475 Field Communicator can connect to the Field Communicator
Easy Upgrade Utility that is available on the Resource CD or DVD. See
the readme file for installation and system requirements. You can
access this file from www.fieldcommunicator.com or the Resource CD
or DVD.
