Grounding - Foundation Fieldbus

Signal wiring of the fieldbus segment cannot be grounded. Grounding out one
of the signal wires will shut down the entire fieldbus segment.

Shield Wire Ground

To protect the fieldbus segment from noise, grounding techniques for shield
wire usually require a single grounding point for shield wire to avoid creating a
ground loop. The ground point is typically at the power supply.
