The Fieldbus diagnostic monitor, FBT-6. is used to examine the

operation of a live Foundation™ fieldbus H1 network without interfering

with its operation. The Monitor is intended for maintenance personnel to

verify network operation or to troubleshoot an errant network.

The FBT-6 checks for retransmissions from each device on the

segment, providing a key performance indicator of the networks health.

Measurements of bus voltage level, device signal level, and peak and

average noise level. It displays the number of devices present on the

segment and indicates when devices are added or removed from the

network. It also detects the presence of a short between either of the

signal wires and the cable shield.
