Connecting to
a Fieldbus
Segment
The online menus display data for the device to which
you are connected. The online menus display critical,
up-to-date process information, including the segment
Live Device List, Block Lists, device menus, and
parameter functionality.
NOTE
It is normal for processes to take longer the greater the
amount of scheduled communication. This is influenced
by the number of devices and the control methods in
place.
Connect the 375 Field Communicator with the
appropriate connectors in parallel with the device. Due to
measurement circuitry, the 375 Field Communicator
fieldbus connections are polarity sensitive. An error
message displays if the device is connected incorrectly.
For information about intrinsically safe connections, see
Appendix B.
NOTE
Dynamic variables shown while online represent the
digital data being sent from the device.
Digital communication is susceptible to electrical noise;
follow proper wiring instructions.
