Signal Termination; Locating Devices - Emerson 3051CF Series Quick Start Manual

Quick Start Guide
2.5.4 Grounding
Signal wiring of the Fieldbus segment cannot be grounded. Grounding out
one of the signal wires will shut down the entire Fieldbus segment.
2.5.5 Shield wire ground
To protect the Fieldbus segment from noise, grounding techniques for shield
wire require a single grounding point for shield wire to avoid creating a
ground loop. Connect the cable shields for the entire segment to a single
good earth ground at the power supply.

2.5.6 Signal termination

For every Fieldbus segment a terminator should be installed at the beginning
and at the end of each segment.

2.5.7 Locating devices

Frequently, different personnel install, configure, and commission devices
over time. A Locate Device capability uses the LCD display (when installed) to
assist personnel in finding the desired device.
From the device Overview screen, select the Locate Device button. This
launches a method allowing you to display a
custom message to display on the device LCD display.
When you exit the Locate Device method, the device LCD display
automatically returns to normal operation.
Note
Some hosts do not support Locate Device in the DD.
2.6 Configure
Each Foundation Fieldbus host or configuration tool has a different way of
displaying and performing configurations. Some use device descriptions (DD)
or DD methods for configuration and to display data consistently across
platforms. There is no requirement that a host or configuration tool support
these features. Use the following block examples to do basic configuration to
the transmitter. For more advanced configurations, see the
Foundation Fieldbus Reference
