Advanced Diagnostics Connection via Diagnostic Bus
This type of diagnostics connection with a PROFIBUS installation is mainly used to forward
diagnostic information to an OPC system. Communication of the diagnostic managers (DTM)
with the diagnostic module takes place via a further software module, the FieldConnex
Diagnostic Server (FDS), and a further hardware component, the COM port converter. In
contrast to direct connection via PROFIBUS DP, the FDS here serves as an interface and a
data access coordinator for the diagnostic module, as well as an OPC DA server, the converter
provides the connection to the RS 485 diagnostic bus of the motherboards.
The diagnostic modules which are part of a device type manager project are not exclusively
allocated to one gateway. Rather, all HD2-DM-A modules connected to the FDS appear at the
FDS node. Alarms and warnings of all diagnostic modules are analyzed centrally in one single
window, the so-called system "diagnostic window".
You can find further information regarding the FDS and the setup, configuration, and
commissioning of the diagnostic module corresponding documentation of the "Advanced
Diagnostic Module HD2-DM-A".

Depending on setup and structure, FDT can either run on the
maintenance application or the operator application.
Description
The FDT specification defines the interaction of DTMs with
host computers or software. An FDT frame application is a
PC–based software including many DTMs for configuration
monitoring and programming of field devices. Both, the
diagnostic manager DTM and the gateway DTM run in an FDT
environment.
A DTM is a device configuration and management software. It
contains a graphic user interface and configures and
diagnoses devices. DTMs are embedded in an FDT frame
application, such as PACTware
interface. The DTM for the advanced diagnostic module is
called diagnostic manager.
