Product Specifications
The Diagnostic Manager – Professional Edition offers extra functionality: the commissioning
wizard generates automated reports; the software displays clear text messages for
troubleshooting of out-of-specification behavior. The OPC server transmits user-selectable
common alarms to the process control system.
For further information refer to the manual "Advanced Diagnostic Module HD2-DM-A".
Advanced Diagnostic Module Relay Contact Output
The advanced diagnostic module relay contact output is a tool for permanently monitoring the
fieldbus physical layer. Using DIP switches, limit ranges can be configured for each physical
layer parameter monitored.
The module distinguishes between 2 alarm types:
Maintenance required alarm
■
Out of specification alarm
■
The "Maintenance required" alarm enables proactive diagnostics. If a value exceeds the limit, a
relay contact opens and the respective segment LED starts to flash yellow. With this proactive
diagnostics, changes within the fieldbus installation can be detected early and fault sources
can be found before communication fails.
If an "Out of specification" alarm occurs (LED flashing red) that means: One of the monitored
physical layer parameters has rapidly declined and moved out of range of "Maintenance
required". A fast examination of the affected segment is crucial to prevent a total dropout of this
segment in the near future.
In order to set the appropriate limit values for your fieldbus installation during commissioning, a
comprehensive diagnostic solution is required. For DIP switch configuration, you can use the
mobile advanced diagnostic module.
