Fieldbus Network Testers
Other testers are used to monitor and characterize network signals. The
Relcom Fieldbus Network Monitor (FBT-3) can be used to examine the
operation of a live fieldbus network, without interfering with its operation.

The FBT-3 will verify the DC voltage on the network and check how noisy the
network is. It can also be used to measure peak noise levels, framing errors, the
number of transmitters on the wire, and what the signal level of the weakest
field transmitter is. In addition, with the FBT-3 you can see the total number of
devices up and running, and what devices are left on the network. The FBT-3
can be purchased from Relcom (
www.relcominc.com ).
