Fieldbus diagnostic monitor

March 2006 Fieldbus & Industrial Networking

MTL has improved its design of its FBT-6 Fieldbus diagnostic monitor. The FBT-6 Fieldbus monitor is a handheld device that allows field personnel to perform a variety of physical layer tests to troubleshoot and commission Fieldbus segments. The FBT-6 builds on the Relcom FBT-3 Fieldbus tester that is established as a standard for Fieldbus H1 test equipment. Additional features have been built into the FBT-6 based on feedback from experienced users of the FBT-3.

Fieldbus diagnostic monitors are most often purchased by end-users and used by their maintenance personnel. Main systems suppliers also use the Fieldbus diagnostic monitors during acceptance testing and for troubleshooting.

MTL reports that its FBT-3 Fieldbus tester is well liked by Fieldbus users, and it has received a lot of valuable feedback on its use. Ninety percent of the ideas for improvement received have been built into the new FBT-6 Fieldbus diagnostic monitor, such as:

* Noise measurement in 3 bands: Fieldbus frequency' low frequency and high frequency. Knowing the frequency of the noise can help identify the cause of the noise.

* Monitor signal level for all devices.

* Monitor signal to shield faults.

* Network retransmissions.

* Reduces commissioning time.

* Download data to PC via USB port. The FBT-6 is supplied with a software utility and USB driver, supporting Windows XP. Automatic data collection and documentation.

* Hazardous area certification. Certification for connecting FBT-6 to intrinsically safe and non-incendive field wiring Fieldbus systems without the need for a gas clearance certificate is in progress.

The Relcom FBT-6 Fieldbus diagnostic monitor is designed for use with Foundation Fieldbus H1 networks.
