Advanced Diagnostics
General Description
2.2.1 Expert System
FieldConnex
tem analyzes all measured values and provides detailed diagnostic messages about any found
issue on the fieldbus, the root causes of the issue and actions necessary to solve them. This
way, the user is relieved from the tedious and time-consuming analysis of all measurements of
the ADM. The expert system takes the segment state (commissioned, non-commissioned) into
account and provides optimized messages for the 2 different use cases.
2.2.2 Commissioning Wizard
The commissioning wizard is a tool for a fast and easy system setup with advanced diagnostic
modules (ADM). It is the recommended way to perform segment commissioning.
The wizard guides you through segment commissioning and determines system and segment
data of your fieldbus installation. The expert system analyzes this data and helps you to solve
any issues found. A comprehensive report on the status of the segment at the time is automati-
cally generated. Based on this information, the commissioning wizard proposes limits for all
system, segment, and field device alarm values. If necessary, you can edit the limit values or
store them on the ADM. After the commissioning wizard is completed successfully, the ADM is
switched to the "commissioned mode" and is ready for plant real-time monitoring.
2.2.3 Diagnostic Gateway Mode (DGW Mode)
The diagnostic gateway (DGW) can be used for the OPC and DTM integration as well as for the
Foundation Fieldbus integration. Only 1 of the 2 types of integration can be used at a time. The
DGW mode must be set to "FDS" or "FF", depending on the selected integration solution.
When a DGW is installed the first time, it automatically selects the DGW mode depending on
whether an FF host or an FDS is connecting to the gateway. In order to change the integration
later on, the DGW mode can be set manually, either via DTMs or via the DGW built-in web
server.
Out of Specification:
The value exceeds the specification limits. At least one value vio-
lated an IEC 61158-2 limit.
Failure:
Field devices that were active on the fieldbus during commission-
ing and are not active anymore are marked as fail in the user
interfaces. The overall segment is classified as out of specifica-
tion. If any hardware failure of the ADM is detected or if the diag-
nostic gateway cannot communicate with the ADM this is also
shown as Fail.
