PROFIBUS Advanced Diagnostics Integration
If the advanced diagnostic module HD2-DM-A is connected via PROFIBUS DP with the
PROFIBUS Power Hub and the HD2-GTR-4PA gateway, a special
“
alarm observer
”
function
allows for intelligent advanced diagnostics integration.
The
“
alarm observer
”
function enables the gateway HD2 GTR 4PA to serve as the interface and
the data access coordinator for diagnostic messages to the distribution control system (DCS)
and the device type manager (DTM). With an activated alarm observer, basic warnings and
alarms of the diagnostic module are integrated into the slave diagnostics and can be parsed by
the DCS via cyclic data exchange. Additionally, these warnings and alarms also appear directly
in the DTM diagnostics dialog (online parameterization) of the PROFIBUS gateways.
The alarm observer can be switched on both acyclically via the DTM and cyclically via DCS
gateway configuration.
Activating the Alarm Observer in the Device Type Manager
1. Open the window
Offline or online parameterization
.
2. Choose
Alarm Observer Enabled
from the drop-down list and confirm with <Return>.
Interface
Description
OPC-DA
Standardized interface allowing access to DCS data (OPC =
OLE for Process Control). Integrated into the FDS.
TCP/IP
Communication protocols used on the Internet and on most
commercial networks.

Diagnostic
Server (FDS)
The FDS works as an interface and a data access coordinator
for the diagnostic module HD2-DM-A that includes the OPC-
DA service.
Field device tool (FDT)
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.
Device type manager (DTM)
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
TM
or in a DCS with an FDT
interface. The DTM for the advanced diagnostic module is
called diagnostic manager.
