a fieldbus loop
To navigate back to the 375 Main Menu, press the

section will guide you through the Fieldbus
Application menus and functions.
Digital communication is susceptible to electrical
noise; follow proper wiring instructions.
The online menu displays data for the device to
which you are connected. The Online menu
displays critical, up-to-date process information,
including the segment live list, block lists, and
parameter functionality. For information about
intrinsically safe connections see Appendix B
"Approval Information".
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
instrument. Due to measurement circuitry the 375
Field Communicator fieldbus connections are
polarity sensitive. If connected incorrectly, an error
message will display.
NOTE
Dynamic variables shown while online represent
the digital data being sent from the device.
