With the advanced diagnostic module (ADM), Pepperl+Fuchs offers enhanced FOUNDATION Fieldbus H1 physical layer diagnostics. The ADM automates commissioning and documentation, monitors the fieldbus segment online, and identifies faults in realtime.

This added functionality is fully integrated in Yokogawa's Plant Resource Manager (PRM), and is designed to monitor the physical layer as an integral part of PRM. PRM is a key platform for the Yokogawa VigilantPlant Asset Excellence initiative.

As an online and centralized automation asset management system, PRM helps both operators and maintenance personnel prevent downtime, and reduces maintenance costs for operational excellence.

With ADM by Pepperl+Fuchs, an embedded expert system learns and interprets the electric values and behaviour of each segment. Plant maintenance receives early, easy-to-understand warnings. This offers a wealth of benefits and is supported by simple user display.

  • Accelerated segment commissioning: due to FieldConnex advanced diagnostics, CENTUM / PRM allows remote segment testing and documentation - eliminating numerous time-consuming and repetitive tasks.
  • Improved plant availability: the fieldbus physical layer is monitored continuously. Critical conditions are detected at an early stage. This allows corrective measures before there is any impact on plant operation.
  • Expert system for fast troubleshooting: In case of an alarm condition, incident-related information describes the nature of the problem and suggests remedies. This accelerates troubleshooting by service technicians.
