Activities Supported by ADM

The Advanced Diagnostic Module supports fieldbus practitioners in all aspects that were previously tedious, time consuming, and required specialized knowledge. These areas are replaced with swift and automated working procedures through software support.

The Commissioning Wizard analyzes the segment after installation or maintenance work. Reports from the expert system point to installation issues, which can be resolved immediately. The expert system then evalutes the segment and provides a baseline report and comprehensive system documentation. It also recommends limits, which are stored in the ADM. Verifying cables and nodes only requires a few mouse clicks, reducing system checkout time by more than 80%.

The expert system continuously compares the baseline to actual values. The ADM communicates summary alarms. The expert system guides the user to possible causes and remedies via actionable information in plain text. The ADM captures snapshots of the physical layer for up to two years. Analysis functions and data exported to the maintenance system enable proactive maintenance strategies to increase overall system availability at a reduced cost.

The Diagnostic Manager provides online access to the Advanced Diagnostic Module. This allows live monitoring of the fieldbus physical layer directly from the control room or remotely by an off site professional. The ADM measures and displays network characteristics such as

• crosstalk/noise
• signal jitter
• resonance

Additionally, it includes a powerful fieldbus oscilloscope that can be triggered up to ten times through fieldbus specific triggers, allowing the trace of complex or intermittent faults that would otherwise be hard to find.

The ADM significantly improves corrections of faults and is the basis for fast diagnosis and repair.
