live troubleshooting
for fieldbus H1
networks
FBT-3
The Fieldbus Monitor, FBT-3
is used to examine
the operation of a live F
OUNDATION
fieldbus™ network
without interfering with its operation. The monitor is
intended for maintenance personnel to verify network
operation or to troubleshoot an errant network. The
Fieldbus Monitor allows the user to quickly assess the
health of a fieldbus network segment by providing
measurements of bus power level, minimum signal
level, and peak and average noise level. It also
displays the number of devices present on the segment
and indicates when devices are added or removed
from the network.
The Fieldbus Monitor is palm-sized for portability and
is powered by the fieldbus so that no batteries or
external power source is required. It includes color-
coded test leads and an LCD display.

area without a gas clearance certificate.
If connected to an IS trunk, even in a safe
area, the gas clearance must cover the
whole system.
