Connecting to
a Fieldbus
loop
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 Device List, block lists, and parameter functionality.
For information about intrinsically safe connections, see
Appendix B, "Product Certifications".
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. An error message will display if the instrument
is connected incorrectly.
NOTE
Dynamic variables shown while online represent the
digital data being sent from the device.
