Application.
4. On the Fieldbus application main menu, choose
Online. The Fieldbus Live Device List appears and
indicates which device or host is acting as the LAS.
The text LAS will appear at the top of the screen only
when the 375 Field Communicator is the LAS. See
Figure 4-5.
If a live fieldbus device is connected to a host acting
as the LAS, a precautionary message will appear. The
Live Device List will then be displayed with key
parameters from the connected device.
If an existing host control system or a device capable
of being the LAS is not connected, the 375 Field
Communicator will act as a temporary LAS on the
segment and produce a warning message. After
reading and following the message instructions, tap
OK to display the Live Device List.
