If a live fieldbus device is connected to a host acting as the LAS, a precautionary
message appears. The Live Device List then appears with the tag name and

If an existing host control system or a device capable of being the LAS is not
connected, the 475 Field Communicator acts as a temporary LAS on the segment

instructions, tap
OK to display the Live Device List.
From the Live Device List, a Block List or a device menu is displayed for a device,
depending on the device description.
