MTL F809F-Plus fieldbus diagnostics module

The Crouse-Hinds series MTL F809F-Plus Fieldbus Diagnostic Module continuously

monitors the performance of eight fieldbus segments, providing information on the

health of the network physical layer. It mounts on a range of MTL power supply

carriers and collects diagnostic information without interruption to normal fieldbus

communications.

As a Foundation Fieldbus™ device the MTL F809F-Plus easily integrates with the

chosen host control system via a fieldbus segment, allowing the network status

and measured parameters to be displayed in the control system’s instrument

management software.

The F809F-Plus builds on the success of the F809F, the industry’s first fieldbus-connected

diagnostic module. New features of the F809F-Plus version include superior immunity

to noise on the ‘communicating’ segment, enhanced short-to-shield detection and

extended power supply voltage measurement range for compatibility with new MTL

power supply types. It may be used as a direct replacement for F809F in existing installations;

when installed using appropriate DD files the full feature set of F809F-Plus become available

with immediate effect.

The F809F-Plus is available with fully updated versions of eEDDL and FDT/DTM user interfaces

that are free to download from the eaton.com website. Improvements include faster operation

and clearer screen layouts, leading to an enhanced user experience. The user interfaces comply

with NAMUR specification NE107 'Self-Monitoring and

Diagnosis of Field Devices', providing clear standardised diagnostic alerts using three of the four

categories; maintenance required, out of specification, and failure.
