Advanced Diagnostics with the PROFIBUS Power Hub
In conjunction with the Advanced Diagnostic Module HD2-DM-A, the
PROFIBUS Power Hub offers extensive analytic and monitoring possi-
bilities for a PROFIBUS fieldbus installation. This diagnosis, from now
on called "Advanced Diagnostics", covers, among other things:
•
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 manual „Advanced Diagnostic Module HD2-DM-A“. You can down-
load this manual from www.pepperl-fuchs.com.
7.1
Advanced Diagnostics Infrastructure
In general, the Advanced Diagnostics setup comprises a number of dif-
ferent hardware (PROFIBUS Power Hub, Advanced Diagnostic Module)
and software components (FDT, DTM). Depending on your require-
ments and your hardware and plant infrastructure, this setup can vary
(see also Advanced Diagnostic Module HD2-DM-A manual).
In order to integrate the Advanced Diagnostic Module HD2-DM-A into a
PROFIBUS Power Hub installation, two different setups can be imple-
mented:
•
direct connection via PROFIBUS DP (recommended) or
•
via the diagnostic bus of the Power Hub motherboard.
7.1.1
Advanced Diagnostics Connection via PROFIBUS DP
In the case of a direct connection of the diagnostic module, communi-
cation between the Diagnostic Manager (DTM) and the diagnostic mo-
dule takes place via PROFIBUS DP and the PROFIBUS Gateway HD2-
GTR-4PA. The Gateway in this case acts as an interface and a data ac-
cess coordinator for the diagnostic module.
No further components are necessary, the diagnostic module is being
addressed within the DTM using "Plug&Play". With this type of connec-
tion, one diagnostic module is statically assigned to one Gateway each.
Thus, this diagnostic module appears as a child node of its correspon-
ding PROFIBUS Gateway in the DTM project.
