Event Capture
The Event Capture setting lets you create an Event Capture file (.rec), which is a log of
communication, input, and output that occurs between the 475 Field Communicator
and a device (HART only). When working with Technical Support personnel, you may
be asked to create an Event Capture file to help troubleshoot issues that cannot be
easily isolated or resolved. The Event Capture file can then be transferred to your PC
using the Field Communicator Easy Upgrade Utility and sent to Technical Support
personnel for review.
Tap the option to activate the Event Capture feature. The option is black when
selected. To delete an existing Event Capture, tap
DELETE EVENT FILE .
NOTE
While Event Capture is enabled, device status and warning messages do not appear.
To create and send an Event Capture file:
1. Double-tap Settings from the Field Communicator Main Menu.
2. Double-tap Event Capture .
3. Tap Turn on HART event capture from the Event Capture window and tap OK .
4. Double-tap HART Application from the Field Communicator Main Menu.
5. Enter a file name for the Event Capture file and tap OK . The file is saved to a default
location.
6. Perform the requested operations to capture the data.
7. Use the Field Communicator Easy Upgrade Utility to transfer the file from your 475
Field Communicator to your PC. See the Easy Upgrade Utility Help for more
information.

CONNECTING TO A
DEVICE
Use the provided lead set and the HART or F
OUNDATION
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 Instrinsically Safe
installations.
