Quick Start Guide
2.6.4 Grounding
Signal wiring of the Fieldbus segment cannot be grounded. Grounding out
one of the signal wires will shut down the entire Fieldbus segment.
2.6.5 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.
2.6.6 Signal termination
For every Fieldbus segment, install a terminator at the beginning and end of
each segment.
2.6.7 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 Find me message or enter 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.
