Fieldbus Monitor FBT-6

Fieldbus Monitor FBT-6

The Fieldbus Monitor, FBT-6, is used to examine a live Fieldbus network without interfering with its operation. The Monitor is intended for commissioning and for maintenance personnel to verify network operation or to troubleshoot an errant network.

The FBT-6 is the next generation to the FBT-3 and provides many enhanced features including the ability to store and download readings from 8 segments via a USB cable to a PC. Reference the data sheet below for complete specifications.

For help with troubleshooting fieldbus problems, see the Fieldbus Physical Layer Troubleshooting Guide.

See the Testing Fieldbus Wiring with an FBT-6 and FBT-5 application note if you are testing fieldbus wiring as part of commissioning.

FBT-6 Assistant software is compatible with Windows XP, Windows Vista, Windows 7, and Windows 8.
