2 Specification

2.1 Overview

The Pepperl+Fuchs PROFIBUS Power Hub System has a modular de­sign. It offers a number of possible combinations so it can be adapted
to the specific requirements of different explosion protection concepts or
the need for increased segment availability.

Functionally, the system may be divided into two component groups:

• Coupling (described in this manual)

• Segment supply (described in the Power Hub manuals)

Modules and Motherboards are assigned to these groups as shown:

•

Date of Issue 24.3.11

Various Power Hub power supply solutions offer either simplex or red­undant power to PROFIBUS PA segments. The Power Hub consists of
a motherboard with sockets for plug-in modules.

• One power supply module per segment in simplex mode or, al­ternatively, two power supply modules per segment in redun­dant mode.

• A physical layer diagnostic module HD2-DM*.

The Power Hub feeds fieldbus segments following the High-Power
Trunk concept for explosion protection. High energy level on the trunk
line is fed to the field instruments via couplers like FieldBarriers or Seg­ment Protectors. A dedicated version of the Power Hub (DART) sup­ports the intrinsically safe concept for fieldbus.

A plug-in Advanced Diagnostic Module for fieldbus is available. This mo­dule monitors the physical layer online and in real time enabling detec­tion of degradation and faults during operation. Measurement data and
alarms are transmitted to the control room thus bringing visibility to the
fieldbus physical layer, which can now be treated as active component
in Plant Asset Management systems. Operators are enabled to decide
on proactive measures to avoid unwanted situations while the plant is
running smoothly.

2.2 Coupling

Coupling involves a Gateway Motherboard and one or, in the case of
redundant coupling, two Gateway Modules.

The purpose of coupling is to adjust the physical transmission proper­ties on the DP side (RS 485) to those of the PROFIBUS PA (in confor­mity with IEC 61158-2). The coupling provides a baudrate of 31.25 kbit/
s on the PA side. In addition, the coupling creates galvanic isolation bet­ween PROFIBUS DP and PROFIBUS PA. The DP/PA coupling of the
PROFIBUS Power Hub System is functionally compatible with the Pep­perl+Fuchs SK 2 System, which is well established on the market.

The coupling of the PROFIBUS PA slave to the PROFIBUS DP is trans­parent. This means that all PA slaves appear on the DP bus and are in­terpreted by the Host as DP slaves. A DP address is also assigned to
the Gateway itself for diagnostic and parameterization purposes.

Although segment supply is part of the PROFIBUS Power Hub System,
it is not described in this manual (only where needed for better under­standing). Please refer to the respective „Generic Power Hub“ manuals
for detailed information on segment supply.

Cyclic data exchange can be connected redundantly to the DP line by
using the redundant Gateway Motherboard MB-FB-GTR and two
HD2-GTR-4PA Gateways.

The Gateway Module HD2-GTR-4PA supports PROFIBUS
"Flying Redundancy“ (chapter “Redundancy Concepts” on page 63) as
well as all non-redundant DP Masters.

In summary, the Gateway is responsible for the following tasks:

• Conversion of the PROFIBUS DP physical layout to that of the
PROFIBUS PA

• Adjusting the DP transmission rate to the PA transmission rate

• Galvanic isolation between PROFIBUS DP and PA

• Elementary functional diagnostics via LEDs

• Ensuring increased availability through redundant coupling of
cyclic data exchange (with redundant layout)

• Acyclic Parameterization of Gateway parameters by
FDT/DTM

• Redundancy diagnostics (with redundant layout)

2.3 Segment Supply

Power is supplied to the field devices through Power Hub Modules on a
Power Hub Motherboard (simplex: 4 Power Hub connection slots, red­undant: 8 connection slots) and via bus lines to the individual segments.

PA segments can receive redundant power supply if the redundant Po­wer Hub Motherboard is used along with two Power Hub Modules for
each segment.

In summary, the supply is responsible for the following tasks:

• Power supply of field devices: power and communication signal

• Redundant supply for high system availability

• Elementary diagnostic information via LEDs

• Advanced Physical Layer Diagnostics via the HD2-DM* Diagno­stic Module and the FDT/DTM software package (see corre­sponding documentation).

2.4 System Components

2.4.1 Motherboards

supply modules, two power supply modules supplying each of the four
segments redundantly. A further socket holds a Diagnostic Module.

2.4.2 Modules for Coupling, Supply and Diagnosis

Gateway module HD2-GTR-4.PA

The Gateway module provides the connection of four PROFIBUS PA
segments to a PROFIBUS DP. In conjunction with Fieldbus Power Mo­dules, PA segments are supplied directly via Fieldbus lines. Coupling is
transparent, so each PA device is addressed and configured as a PRO­FIBUS DP device.

The HD2-GTR-4PA module includes four full-featured PA masters, who
perform data exchange time independently.

The FDT/DTM based PC software package allows the parameterization
of the Gateway and offers several status and diagnostic functionalities.
Used in connection with the corresponding motherboard, two Gateways

provide redundant coupling. The HD2-GTR-4PA supports PROFIBUS
„Flying Redundancy“ as well as all non-redundant masters.

Power modules HD2-FB*

Power Modules supply electrical power to segments. They couple the
supply current to the two-wire Fieldbus cable while maintaining the high­est signal quality.

Diagnostic modules HD2-DM*

Diagnostic modules are divided into the Basic Diagnostic Module HD2­DM-B and the Advanced Diagnostic Module HD2-DM-A. The diagnostic
modules provide various system diagnostics.

2.5 Recommended System Combinations

2.5.1 Case 1: Fully Redundant

In the fully redundant system, both coupling of PROFIBUS DP to
PROFIBUS PA and the supply of the four segments are designed red­undantly. The fully redundant PROFIBUS Power Hub consists of the fol­lowing components:

• Gateway motherboard MB-FB-GTR

• Power Hub motherboard MB*-4R.GEN

• 2 x HD2-GTR-4PA

• 8 x Power Modules

• 1 x Diagnostic Module

• 1 x Sub-D cable to connect motherboards

The fully redundant system offers the highest protection against indivi­dual failures or failure of all PA segments of PROFIBUS.

2.5.2 Case 2: Redundant Coupling

In this case, coupling is designed redundantly, but there is only one
supply per segment (simplex). The redundantly coupled system con­sists of the following components:

• Gateway motherboard MB-FB-GTR

• Power Hub motherboard MB-FB-4.GEN

• 2 x HD2-GTR-4PA

• 4 x Power Modules

• 1 x Diagnostic Module

• 1 x Sub-D cable to connect motherboards

Redundant coupling ensures communication of the four PA segments.
Failure of one segment has no effect on the other three segments.

16

Date of Issue 24.3.11

2.5.3 Case 3: Simplex

In the simplex system, both the coupling of DP to PA and the supply of
the four segments are single (simplex). The simplex system consists of
the following components:

• Gateway motherboard MB-FB-GT

• Power Hub motherboard MB-FB-4.GEN

• 1 x HD2-GTR-4PA

• 4 x Power Modules

• 1 x Diagnostic Module

• 1 x Sub-D cable to connect motherboards

Combining a simplex Gateway Motherboard and a redundant Power Hub
Motherboard also makes a fourth combination possible. Pepperl+Fuchs
does not recommend using this arrangement. Since a fault in the cou­pling of DP to PA results in failure of all four segments together, but the
failure of a single segment does not have any effect on the remaining
segments, increased segment availability can be achieved most easily
with redundant coupling (as described in case 1 and case 2).

3.2 Shield/Grounding

•

The screen/shield of the Profibus cable on the HD2-GTR-4PA is con­nected directly to the screen/ground connection clamp of the mother­board.

If the Profibus DP cable leads into a hazardous area the screen/ground
connection clamp has to be connected to safety earth.

There might be a requirement to earth all exposed metal parts as a mat­ter of course.

•

Earth Connection

Take care about good earthing practice and ensure a clean earth at all
times.
