Adding physical layer diagnostics to the fieldbus infrastructure of a processing plant is now faster and easier than ever! Our newest addition to our range of advanced diagnostic modules (ADM) provides the process industry with a solution that is up and running within minutes, and requires neither engineering efforts nor software installation.

The new ADM with relay output is a plug and play module that attaches to the power hub and monitors up to four fieldbus segments. It also monitors vital signal quality criteria:

• Signal level
• Noise
• Jitter

By monitoring signal quality, the module HD2-DM-A.RO reliably detects critical operating conditions within the monitored segments, and automatically triggers an alarm via the power hub's voltage-free alarm contact.

The new plug and play ADM module HD2-DM-A.RO combines a set of unique features to offer fieldbus physical layer monitoring for any infrastructure:

• Monitoring of up to four segments
• Simple configuration via DIP switches
• Integration into power hub
• No engineering required
• Alarm indication via alarm contact of the power hub

For fast and easy segment testing and commissioning of fieldbus segments, we recommend our Mobile Advanced Diagnostic Module DM-AM-KIT. The highly compact unit connects to any notebook running a mobile version of the Diagnostic Manager software. It is the perfect tool for the mobile field technician to obtain detailed segment analysis and allows fast troubleshooting after the ADM has indicated an alarm condition. It provides unique mobility features and is
well-suited for commissioning and troubleshooting purposes:

• Portable monitoring of one fieldbus segment
• Power via USB
• Data communication via USB
• Software functionality close to stationary ADM

Pepperl+Fuchs provides the new plug and play ADM module as an entry solution offering essential fieldbus physical layer monitoring. It contributes to increased plant availability by pointing to potential trouble spots long before they can affect plant operation.
