Advanced Diagnostics with the PROFIBUS Power Hub
Together with the advanced diagnostic module HD2-DM-A, the PROFIBUS Power Hub offers
extensive analytic and monitoring options for a PROFIBUS fieldbus installation. This special
diagnostics called "advanced diagnostics", among other things includes the following features:
Proactive plant monitoring
■
Analysis of the fieldbus physical layer (jitter, noise, etc.)
■
Assistance during the complete fieldbus life cycle
■
Wizards for commissioning and fault detection
■
Integrated oscilloscope function
■
Further information regarding advanced diagnostics can be found in the corresponding
documentation of the "Advanced Diagnostic Module HD2-DM-A". You can download this
manual from www.pepperl-fuchs.com.

Advanced Diagnostics Infrastructure
In general, the advanced diagnostics setup comprises a number of different hardware
(PROFIBUS Power Hub, advanced diagnostic module) and software components (FDT, DTM).
Depending on your requirements and your hardware and plant infrastructure, this setup can
vary. See also the corresponding documentation of the "Advanced Diagnostic Module HD2-
DM-A".
In order to integrate the advanced diagnostic module HD2-DM-A into a PROFIBUS Power Hub
installation, one of the following 2 different kind of setups can be implemented:
Direct connection via PROFIBUS DP (recommended)
■
Via the diagnostic bus of the Power Hub motherboard
■
Advanced Diagnostics Connection via PROFIBUS DP
In the case of a direct connection of the diagnostic module, communication between the
diagnostic manager (device type manager) and the diagnostic module takes place via
PROFIBUS DP and the PROFIBUS gateway HD2-GTR-4PA. The gateway then acts as an
interface and a data access coordinator for the diagnostic module.
No further components are necessary. The diagnostic module is being addressed in the device
type manager using "Plug&Play". With this type of connection, one diagnostic module is
statically assigned to one gateway each. Thus, this diagnostic module appears as a child node
of its corresponding PROFIBUS gateway in the device type manager project.
