The Emerson 475 Field Communicator provides access to the numerous HART and FOUNDATION fieldbus devices currently in use. It is able to configure FOUNDATION fieldbus devices, perform diagnostics for effective start-up and troubleshooting of fieldbus segments, and create a quality segment by diagnosing the network DC voltage and average noise. It also can detect power supply problems by monitoring low frequency noise on a segment and locate incorrect terminations and faulty devices by diagnosing the communications signal level. For HART loops, the 475 Field Communicator allows you to verify whether the DC voltage in the loop is correct. By using the ValveLink Mobile application you can quickly perform tests including valve signature, dynamic error band, PD one button sweep, and step response on HART Fisher FIELDVUE digital valve controllers.

The user interface is via a large colour display which utilises touch screen technology along with physical navigation buttons which are comfortable to operate one handed even with gloves on. To ensure it is reliable in the field the 475 Field Communicator is designed to take the knocks and shocks from normal use as well as having a protective rubber boot that provides added protection. Both the rubber boot and 475 housing are also designed to limit the buildup of static electrical energy.
