3 General Information

3.1 Intended Use

Pepperl+Fuchs PROFIBUS Power Hub serves as a Segment Couplerfor connecting PROFIBUS PA segments to a PROFIBUS DP. ThePROFIBUS Power Hub can be used in all system environments in com-pliance with industry standard PROFIBUS DP Masters.

Segment Couplers are the interface between the PROFIBUS DP andPROFIBUS PA. They ensure communication and galvanic isolationbetween PROFIBUS DP and PROFIBUS PA.

PROFIBUS PA is an extended version of the PROFIBUS DP that allowsfor the physical transmission specifications of IEC 61158-2. Fieldbusdevices receive their electrical supply through the transmission lines.

The combination of PROFIBUS Power Hub components makes it pos-sible to connect and supply four PROFIBUS PA segments per Gatewayto the PROFIBUS DP.

3.2 Identification

More recent documentation also uses the term PROFIBUS MBP in con-nection with PROFIBUS PA. MBP stands for Manchester Coded BusPowered. PROFIBUS PA and PROFIBUS MBP are identical. The follow-ing section uses only the term PROFIBUS PA, which has been widely in-troduced and is current. PROFIBUS MBP-IS refers to the intrinsicallysafe version of the PROFIBUS MBP.

! Mounting of HD2-*-Modules on the Motherboard

•

The housing of HD2-*-Modules meets the degree of protection classIP 20. It is intended for mounting on the Fieldbus Power Hub mother-boards MB-FB-*.

To install a new module on the board proceed as follows:

1. Carefully center the polarisation holes and mate the two con-nectors, then gently press down the module.

2. Push down the red „Quick-LOK“ tabs on each side of the moduleto fix it to the panel (no tools required).

There is a special connection slot for the diagnostic modules HD2-DM-Band HD2-DM-A on the Power Hub motherboard, which is labeled „Dia-gnostic Module only“. Do not try to plug other modules into this connec-tion slot. Other modules may be damaged.

In the case of redundant segment supply, make sure to either use twogalvanically isolated Power Supply Modules or two galvanically not iso-lated Power Conditioner Modules for the same segment. Using two mo-dule types on the same segment will result in a fault if a DiagnosticModule is connected.

! Assigning the Built-In-Slave Address

To assign an address to the Built-In-Slave of the Gateway HD2-GTR-4PA, follow these steps:

1. Place the eight individual switches of the DIP switch in the cor-rect positions to generate the desired address of the Built-In-Slave as the sum of powers of two from left to right (see the la-bel on the Gateway Module).

2. Restart the Gateway by disconnecting it from the power supply orby unplugging the Gateway Module and reconnecting it.

The Built-In-Slave address is assigned.

3.5 Repair and Maintenance

The measurement properties of the described devices are stable overlong periods of time. Therefore, regular adjustment or service or the likeare unnecessary.

3.6 Disposal

Disposal of devices and their packaging material must be performed incompliance with the applicable laws and guidelines of the correspon-ding country.

The devices do not contain batteries which need to be disposed of se-parately from the products.

In non-redundant operation, Built-In-Slave addresses are permitted inthe range from 0-125; in redundant operation, addresses between 0 and61 are permitted.Assigning an invalid address for the type of operation in question causesthe Built-In-Slave to be deactivated.

In redundant operation, an address must be assigned to the Built-In-Slave.

In the case of redundant coupling, both Gateways need to be restartedat the same time.

4.1 Overview

The Pepperl+Fuchs PROFIBUS Power Hub System has a modular de-sign. It offers a number of possible combinations so it can be adaptedto the specific requirements of different explosion protection concepts orthe need for increased segment availability.

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

• Coupling• Segment supply

Modules and Motherboards are assigned to these groups as shown be-low:

4.2 Coupling

Coupling involves one or, in the case of redundant coupling, two Gate-way Modules.

The purpose of coupling is to adjust the physical transmission proper-ties on the DP side (RS 485) to those of the PROFIBUS PA (in confor-mity 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 bet-ween PROFIBUS DP and PROFIBUS PA. The DP/PA coupling of thePROFIBUS Power Hub System is functionally compatible with the Pep-perl+Fuchs SK 2 System, which is well established on the market.

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

Cyclic data exchange can be connected redundantly to the DP line byusing the redundant Gateway Motherboard MB-FB-GTR and twoHD2-GTR-4PA Gateways.

The Gateway Module HD2-GTR-4PA supports PROFIBUS"Flying Redundancy“ (chapter “Redundancy Concepts” on page 73) aswell 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 thePROFIBUS 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)

4.3 Segment Supply

Power is supplied to the field devices through Power Hub Modules con-nected to the Power Hub Motherboard (simplex: 4 Power Hub connec-tion slots, redundant: 8 connection slots) and via bus lines to the indivi-dual segments.

One Power Module is used for simplex power supply. Two galvanicallyisolated Power Supply Modules or two non-galvanically isolated PowerConditioner Modules are required for each segment receiving power forredundant power supply.

Power Hub Modules are equipped with integrated LEDs that indicate thefunctional capability of the module as well as correct output voltage orfailure of the module (see below).

PA segments can receive redundant power supply if the redundant Po-wer Hub Motherboard is used along with two Power Hub Modules foreach 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-A Dia-

gnostic Module and the FDT/DTM software package (see corre-sponding documentation)

4.4 System Components

4.4.1 Motherboards

Gateway motherboard simplex MB-FB-GT

The gateway motherboard simplex MB-FB-GT allows the connection ofthe Fieldbus Power Hub motherboards MB-FB-4.GEN or MB-FB-4R.GEN using a standard cable. A socket will hold the DP/PA GatewayHD2-GTR-4PA. The Built-In Slave of the HD2-GTR-4PA can be addres-sed using the DIP switch on the motherboard.

Gateway motherboard redundant MB-FB-GTR

The gateway motherboard redundant MB-FB-GTR allows the connec-tion of the Fieldbus Power Hub motherboards MB-FB-4.GEN or MB-FB-4R.GEN with a standard cable. Two sockets will hold two DP/PA Gate-ways HD2-GTR-4PA. The Built-In Slaves of the HD2-GTR-4PA modulescan be addressed using the DIP switch on the motherboard.

Power Hub motherboard simplex MB-FB-4.GEN

The MB-FB-4.GEN allows the supply of four Fieldbus segments as wellas the direct connection of the PROFIBUS DP/PA Gateway Mother-boards MB-FB-GT or MB-FB-GTR with a standard cable. Four socketswill hold the Power Modules. The modules are available for different ex-plosion protection concepts and with various isolation levels. A furthersocket will hold a Diagnostic Module

undancy per segment. The modules are available for different explosionprotection concepts and with various isolation levels. A further socketwill hold a Diagnostic Module.

4.4.2 Modules for Coupling, Supply and Diagnosis

Gateway module HD2-GTR-4.PAThe HD2-GTR-4PA provides the connection of four PROFIBUS PA seg-ments to a PROFIBUS DP. In conjunction with Fieldbus Power Modules,PA segments are supplied directly via Fieldbus lines. Coupling is trans-parent, so each PA device is addressed and configured as a PROFIBUSDP device. The FDT/DTM based PC software package allows the para-meterization of the Gateway and offers several status and diagnosticfunctionalities. Used in connection with the corresponding motherboard,two Gateways provide redundant coupling. The HD2-GTR-4PA sup-ports PROFIBUS „Flying Redundancy“ as well as all non-redundantmasters.

Power modules HD2-FB*Power Modules supply electrical power to segments. They couple thesupply current to the two-wire Fieldbus cable while maintaining the high-est signal quality. There is a distinction between Power Supply Modulesand Power Conditioner Modules.

• Power Supply Modules (HD2-FBPS-*) are galvanically isolatedmodules. The supply voltage of the segments is between 15Vand 30V, depending on the module (see table below).

• The non-galvanically isolated Power Conditioner Module HD2-FBCL-1.500 supplies power to field devices depending on theinput voltage. Topologies with high output can be implementedin the field. In combination with Segment Protectors, field de-vices can be connected in the safe area, in Zone 2 and in pro-tection type Ex nL. The FieldBarrier also makes it possible toensure an intrinsically safe device connection in Zone 1. Shortcircuit limiting for the connection line to the Host is integratedinto the Power Conditioner Module

Diagnostic modules HD2-DM*Diagnostic modules are divided into the Basic Diagnostic Module HD2-DM-B and the Advanced Diagnostic Module HD2-DM-A• Basic Diagnostic Module HD2-DM-B

The Diagnostic Module HD2-DM-B provides several basic sy-stem diagnostics. It checks if the bulk power supplies are wor-king in the proper voltage range and monitors the connectedtrunks for overload and short circuit. All Power Hub Modules arechecked for proper function, in case of redundant versions a sy-stem integrity check is performed. Malfunctions are indicated by

LEDs and can be transmitted by voltage free contact connec-tion.

• Advanced Diagnostic Module HD2-DM-AThis Diagnostic Module offers advanced diagnostic functions, itanalyzes signal and segment parameters such as supply cur-rent and short circuit, but system and Physical Layer valuessuch as noise, jitter level and unbalance are also analyzed.Measured values/error messages are displayed via integratedLEDs and the FDT based FieldConnex Diagnostics DTMPackage. The integrated powerful oscilloscope function visua-lizes the communication on each segment. The continuous mo-nitoring of all relevant physical layer parameters proactively de-tects degradations before the segment communication fails.

4.5 Fieldbus Power Hub Basic Diagnostics

The Power Modules and the Basic Diagnostic Module HD2-DM-B per-form a number of basic system diagnostics.

4.5.1 Power Modules (HD2-FB-*)

Each Power Modul monitors its own supply power (green LED: ok). Itadditionally checks if there is an overload or a short circuit (red LEDflashing).

4.5.2 Basic Diagnostic Module (HD2-DM-B)

There is a green Power LED for each of the bulk power supplies. Aflashing red LED indicates module failure. If a supply power, module orsystem integrity fault occurs, the relay contact opens.

System integrity is only checked in redundant systems. For each se-gement, it is checked if two modules of the same kind are connected orif no modules are connected. An alarm is triggered if only one moduleis connected to a redundant slot and if a Power Conditioner and a PowerSupply Module are plugged into a redundant slot.

4.8 Recommended System Combinations

4.8.1 Case 1: Fully Redundant

In the fully redundant system, both coupling of PROFIBUS DP toPROFIBUS PA and the supply of the four segments are designed red-undantly. The fully redundant PROFIBUS Power Hub consists of the fol-lowing components:

• MB-FB-GTR• MB-FB-4R.GEN• 2 x HD2-GTR-4PAs• 8 x Power Modules• 1 x Diagnostic Module• 1 x Sub-D cable for connecting to Motherboards

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

4.8.2 Case 2: Redundant Coupling

In this case, coupling is designed redundantly, but there is only onesupply per segment (simplex). The redundantly coupled system con-sists of the following components:

• MB-FB-GTR• MB-FB-4.GEN• 2 x HD2-GTR-4PAs• 4 x Power Modules• 1 x Diagnostic Module• 1 x Sub-D cable for connecting to Motherboards

In conjunction with the FDT/DTM based PC software package it provi-des basic analyses of signal and segment parameters e. g. measure-ment of specific system and node physical layer values e. g. increasing noise or jitter levels and unbalance detection. The integrated powerful oscilloscope function enables to visualize the communication at a seg-ment. The continuous monitoring of all relevant physical layer parame-ters allows to detect proactive degradations before the segment communication fails.As a part of the PACTwareTM FieldConnex DTM collection, a DTM is of-fered which supports e. g. alarming, trending, report generation and oscilloscope function.

You can find a complete overview of the Advanced Diagnostic Solutionson the individual instruction manuals and data sheets of the two devices.They can be downloaded from www.pepperl-fuchs.com.

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

4.8.3 Case 3: Simplex

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

• MB-FB-GT• MB-FB-4.GEN• 1 x HD2-GTR-4PA• 4 x Power Modules• 1 x Diagnostic Module• 1 x Sub-D cable for connecting to Motherboards

4.9 Component Overview

Combining a simplex Gateway Motherboard and a redundant Power HubMotherboard also makes a fourth combination conceivable. Pep-perl+Fuchs does not recommend using this arrangement. Since a faultin 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 re-maining segments, increased segment availability can be achieved mosteasily with redundant coupling (as described in case 1 and case 2).

5.3 Commissioning of Cyclic Data Exchange

An appropriate configuration tool is required to configure cyclic data ex-change (defining the slave, effective data, etc.) with a PROFIBUS-DPMaster Class 1.

! Commissioning of Simplex System and Redundant System

The following section describes communication start-up of the HD2-GTR-4PA:

1. If necessary, convert existing GSD files of PA slaves with theP+F-GSD converter and then integrate them into the configura-tion tool

2. Integrate the GSD file of the HD2-GTR-4PA into the configurationtool

3. Add Built-In-Slave (BIS) of the HD2-GTR-4PA to the DP bus con-figuration

Because the DP/PA-Gateway is already a DP slave, its device GSDdoes not need to be converted. The GSD file of the HD2-GTR-4PA isavailable for download at www.pepperl-fuchs.com.

5. Adjust the Watchdog. Rough value: 5 seconds (see chapter “Addi-tional Information about Watchdog time” on page 41)

! Additional steps for Redundant Coupling

The following additional steps are required for redundant coupling:

1. Add the Built-In-Slave (BIS) of the second DP/PA Gateway tothe DP bus configuration

2. Assign the BIS address set on the DP bus (the address of the firstBIS + 64) to the second DP/PA Gateway on the DP bus.

! Additional steps for use of fiber-optical zones

If Coupling is designed redundantly and the DP bus uses optical fiber as a communication medium, the following additional steps must be performed:

Adjust the retry limit according to the baudrate (see chapter “Addi-tional Information on Adjusting Retry” on page 44).

5.3.1 Additional Information on the GSD Conversion

Because coupling is transparent, PROFIBUS PA nodes are treated likePROFIBUS DP slaves by the PROFIBUS DP Master. This also appliesto start-up and configuration.

To configure and start up a PROFIBUS PA slave with a configurationtool, the GSD file must be integrated into it first.

The following distinctions are important to recognize in GSD files forPROFIBUS PA slaves:• Is the file a profile GSD or a manufacturer-specific GSD?• is the GSD designed for communication via the RS 485 inter-

face (DP-GSD) or by the interface in conformity withIEC 61158-2 (PA-GSD)?

If a profile GSD is being used, the filename indicates whether it is a DP-GSD or a PA-GSD.

For example, file PA039733.gsd is the profile GSD for 4 binary outputs.The "PA“ in the filename means it is a PROFIBUS PA slave. The follo-wing "0“ indicates it is a DP-GSD. The filename of the PA-GSD for the

• PA slaves do not take part in cyclic data exchangeThe Built-In-Slave (BIS) of the first DP/PA Gateway must take part in cy-clic data exchange. If it does not the connected PA slaves will also notenter into cyclic data exchange.Add the BIS of the Gateway to the DP bus configuration!

same profile is PA139733. The "1“ after the PA abbreviation identifies itas a PA-GSD.

If manufacturer-specific GSDs are used, for example to make use offunctionality that falls outside the profile, the following convention iden-tifies whether it is a DP-GSD or PA-GSD:

• If you have not done so already, integrate the GSD into yourconfiguration tool.

• Check in your configuration tool what baud rates are supported.

If a baudrate of 31.25 kBd is supported, the file is a PA-GSD. Normallyonly baudrates of 31.25 kBd, 45.45 kBd and 93.75 kBd are supportedby the PA-GSD.

If transmission rates in accordance with the PROFIBUS specificationare used (IEC 61158), i.e. baudrates of 9.6 kBd to 1.5 MBd or 12 MBd,the file is a DP-GSD. Some PROFIBUS PA field device manufacturersdo not offer any PROFIBUS DP-GSDs. In this case the existing PROFI-BUS PA-GSD must be converted. The conversion software (GSD con-verter) is available at no cost from www.pepperl-fuchs.com. The purpo-se of this conversion software is exclusively to enter missingtransmission rates and to set specific bus parameters to values that al-low for problem-free operation of the PROFIBUS DP.

Converting the GSD file imposes the following functional restrictions ifthat was previously supported by the original GSD file:

• FREEZE and SYNC functionality is deactivated. Thesefunctions are used in PROFIBUS DP for synchronization of sen-sors/actuators. Since work is possible on the PROFIBUS DPside (Host side) at transmission speeds of up to 12 MBd and onthe PROFIBUS PA side (field side) at a rate of 31.25 MBd, pro-blem-free operation cannot be guaranteed.

Some PROFIBUS functions are not currently supported. If the field de-vice is intended to support one or more of the following functions, awarning will point out that this will no longer be the case after the con-version. This affects the following functions:

• C1 services

The following functions of PROFIBUS DP V2:

• Data Exchange Broadcast (Publisher/Subscriber)• Isochronous mode , i.e. cycle-synchronous transmission

! Using the Pepperl+Fuchs GSD converter

To convert GSD files, follow these steps:

1. Start program PFGSDCX.EXE

The following dialog appears:•

2. Switch to the directory in which the GSD files to be converted re-side

3. Select the GSD files to be converted

4. Switch to the directory where you want to save the GSD files

5. Convert the GSD files by clicking on the "Process GSD -->“ button

Another window appears with information about the result of the conver-sion process.

The Advisory Board of the PROFIBUS User Organization has agreedthat certified GSD files changed by the Pepperl+Fuchs GSD convertersoftware will not lose their certificate.

You can select multiple files to convert with the CTRL and SHIFT keys.Files with a "+“ before the file name are the result of an earlier conver-sion. These files cannot be converted again. If you attempt to do so, anerror message will appear. Files beginning with a "-“ are not the result ofa conversion and can be converted. Double-clicking on a file allows youto view and edit it.

5.3.2 Additional Information about Watchdog time

PROFIBUS devices can be activated by a monitoring mechanism thatmonitors each time interval of the cyclic data exchange to make certainthe PROFIBUS Master is still active. The time measurement is per-formed in the PROFIBUS slave.

If Watchdog is activated and the time TWD since the last cyclic call hasexpired, the device leaves cyclic data exchange, reverts to its originalstate (Wait_prm) and sets the outputs to a safe state.

The value of time TWD and activation of the Watchdog are transferred inthe parameterization frame from the PROFIBUS Master to the PROFI-BUS slave during the boot process (transition to cyclic data exchange).Generally the time TWD is dimensioned user-specifically (not device-specifically and not in the GSD). The value is low limited by cycle times.

Usually the time TWD is entered by the configuration tool. Because ofthis, the Watchdog setting in HD2-GTR-4PA is "Transparent“ by default.There are some configuration tools in which the Watchdog is set to onceper PROFIBUS Master and others in which the Watchdog can be indi-vidually adjusted for each PROFIBUS PA node. This has no effect onthe value of the Watchdog.

In many tools the time TWD is automatically calculated based on the cy-cle time of the Master with the corresponding Baudrate.

At high baudrates on the PROFIBUS DP side (for example 12 MBd) cy-cle times on the PA side may be higher by a factor of 300. If a PROFI-BUS PA is parameterized directly with a time TWD calculated at a highMaster baudrate (DP), the time is generally less than the PA cycle andthe device does not enter into data exchange. In this case the Watchdogtime must be set in the HD2-GTR-4PA to "Fixed Value" and a higherWatchdog time than the one calculated by the configuration tool mustbe set.

• Watchdog reprogramming during cyclic communication!

DPV1 slaves leave cyclic communication because the DPV1 standarddoes not permit any Watchdog change during operation.

The BIS of the DP/PA Gateway performs diagnostics in the DTM and cy-clically to determine whether the Watchdog time (TWD) is sufficient.





Dat

e of

Issu

e 1.

3.06

To ensure safe and reliable operation of the HD2-GTR-4PA, the follo-wing bus parameters should be used:

• Baudrate: 45.45 kBd ... 12 MBd• Watchdog time: TWD = 5 s• Standard bus parameters in conformity with the PROFIBUS DP

standard

The Watchdog time value above is one derived from experience andusually works. If you discover that the Watchdog time is too long (slavesare not switching to a safe state quickly enough) or too short (slaves areswitching to the safe state without the Master having failed), the timemust be calculated. Depending on the configuration tool you are usingyou can:• parameterize just one Watchdog time TWD for the entire PRO-

FIBUS system. In this case, the greatest delay time must beused as the basis for determining TWD

• parameterize one Watchdog time TWD for each individual slave





Dat

e of

Issu

e 1.

3.06

The set (parameterized) time TWD must be greater than the maximumdelay time that occurs TV_max. It is composed of the following elements:

TV_max = TCycle_DP + TCycle_PA_Channel

where TCycle_PA_Channel = Cycle time of the PROFIBUS PA channel

TCycle_DP = Cycle time of the PROFIBUS DP

Pepperl+Fuchs recommends triple PROFIBUS PA cycle time.

The PA cycle time TCycle_PA_Channel depends on:• the number n of nodes on a channel• The effective data length L

The effective data length L is a unitless variable calculated as the aver-age input and output effective data quantity (in bytes) of all devices.

The cycle time is calculated approximately:

TCycle_PA_Channel = n * (0.256 ms * L + 12 ms) + 40 ms

Two types of Watchdogs can be configured on the HD2-GTR-4PA in cy-clic or acyclic data exchange (chapter “Watchdog Time in the DTM” onpage 63):

• Transparent Watchdog: The Watchdog time on the DP side isthe same as on the PA side (= default setting).

• Fixed Watchdog: A Watchdog time is set on the HD2-GTR-4PAfor the PA side that is different than the DP side.

The HD2-GTR-4PA measures the current cycle time of each PA seg-ment and generates a diagnostic message if the Watchdog time is tooshort.Then the Watchdog time must be increased. The Gateway diagnosticsare based on the following formula: 2 x TCycle_PA_Channel + 500 ms

6.3 Fieldbus Power Supply HD2-FBPS-1.500

6.3.1 Energy-limited, Non-incendive Field Wiring for Field DevicesUsing the Fieldbus Power Supply HD2-FBPS-1.500

If the general purpose Fieldbus Power Supply HD2-FBPS-1.500 is usedin conjunction with Pepperl+Fuchs Segment Protectors (SPs), the out-puts of the SP will be classified EEx nL (energy limited) or non-incendi-ve field wiring.

Due to the unlimited trunk energy, live work at the trunk is not permittedwithout gas clearance. However, live connect or disconnect at the out-put spurs of the SP is allowed, if the following Entity Concept safety eva-luation/requirements for the field devices are followed:

32 V M Ui (field device)

Li field device + L cable M 0.25 mH

Ci field device + C cable M 100 nF

No special safety requirements exist for the host interface, provided thehost itself is installed in the safe area. If the host interface is installed inZone 2 or Div. 2, a Declaration of Conformity or a Certificate of Compli-ance for EEx nA, non-incendive equipment must be provided.

Field devices with a voltage of Ui N 32 V, certified EEx nL or EEx i areallowed to be connected to the outputs of the SP under a Zone 2 energylimited, Div. 2 non-incendive field wiring rating.

Today only a small quantity of field devices certified for EEx nL or EEx iwith Ui N 32 V are available. Traditionally, the majority of EEx i field de-vices are certified according to the Entity concept with Ui = 24 V or ac-cording to FISCO with Ui = 17.5 V.

6.3.2 Advantages

High power is made available for the field devices due to the high volta-ge and current of the feeding Fieldbus Power Supply. From a topologypoint of view, this will always offer a superior load capability.

6.3.3 Disadvantages• Only a few field devices match the parameters required for this

application.• No hot work is permitted at the trunk.• Safety calculations are required to be performed.

Similar to the topology shown in the previous chapter, the voltage is notlimited by the Segment Protector. Instead the voltage is limited by theFieldbus Power Supply HD2-FBPS-1.23.500 to a maximum voltage of24 V. In conjunction with the current limitation of the Segment Protector,the outputs of the SP are rated energy limited, non-incendive field wi-ring. The Zone 2/Div. 2 Segment Protectors supply an energy limitedcurrent to each spur (i. e. EEx nL / non-incendive), which allows the ca-ble and devices the benefits normally only given in intrinsically safe sys-tems. Instruments are treated exactly the same as intrinsically safe in-struments, thus they can be live connected or disconnected without therisk of ignition. Another advantage is that the spur cables are exemptfrom mandatory mechanical protection, saving both weight and cost. Asneeded in a standard intrinsically safe configuration, Entity parametersmust be calculated and compared for the instruments and the cables ofthe individual spurs.

The Declaration of Conformity or Certificate of Compliance must alsostate the "passivity" of any host interface. In other words, the host mustnot be an active power source or it must be certified energy limited withUo M 24 V.

Field devices with a voltage of Ui N 24 V certified EEx nL or EEx i arepermitted to be connected to the outputs of the SP under a Zone 2 en-ergy limited, Div. 2 non-incendive field wiring rating.

The majority of field devices with Ui N 24 V are Ex i devices certified ac-cording to the Entity Concept.

6.5.1 Energy-limited, Non-incendive Field Wiring According to FNICOfor Field Devices Using the Fieldbus Power Supply HD2-FBPS-1.17.500

During later developments of intrinsically safe Fieldbus, Pepperl+Fuchsconsidered an energy limited, non-incendive field wiring concept equi-valent to FISCO (Fieldbus Intrinsically Safe COncept) and derived FNI-CO (Fieldbus Non-Incendive COncept). This energy limited, non-incen-dive version of FISCO, uses fewer safety components, but offers anotable performance advantage due to reduction in safety factor or mar-gin for Zone 2 and Div. 2 equipment.

FNICO works by limiting the supply voltage to 17.5 V maximum (so thatFISCO instruments may be used) and limiting the output short circuitcurrent to non-incendive levels. This satisfies both non-incendive andZone 2 installations for Gas Group IIC (Group A, B) or IIB (Group C) orIIA (Group D) environments. The FNICO ignition curve was empiricallyderived, then published in IEC 60079-27, and can be used by any Field-bus Power Supply manufacturer in its present form:

The current limit dictated by this table is still restrictive, particularly for atrunk in Gas Group IIC or Group A/B. A deviation from the concept usedby Pepperl+Fuchs addresses the restriction by allowing the main trunkto be maintained at a Zone 2/Div. 2 level using a non arcing EEx nA ra-ting or Div. 2 wiring methods. This allows unrestricted current from thePower Supply. The Zone 2/Div. 2 Segment Protectors supply an energylimited current to each spur (i. e. EEx nL/non-incendive), which allowsthe cable and devices the benefits normally only given to intrinsicallysafe systems.

Because FNICO is essentially an intrinsically safe system, instrumentsare treated exactly the same as intrinsically safe instruments, thus theycan be live connected or disconnected without the risk of ignition. Ano-ther advantage is that the spur cables are exempt from mandatory me-chanical protection, saving both weight and cost.

The Declaration of Conformity or Certificate of Compliance must alsostate the "passivity" of any host interface. In other words, the host mustnot be an active power source or it must be certified energy limited withUo M 17.5 V.

7 Operation

In PROFIBUS, two types of communication exist:• cyclic and• acyclic data exchange.

In cyclic data exchange, user data is exchanged between the Master(Process Control System) and Slave (field device) at regular intervals.User data includes measurement values, limit position feedback andoutput data, etc. The bus cycle time depends essentially on the numberof nodes and the amount of data being transmitted.

In acyclic data exchange, "service" data, for example device paramete-rization or diagnostic information, is transmitted.

A number of parameters of the HD2-GTR-4PA Gateway Module can beadjusted both through acyclic parameterization (using the DTM) and viathe Process Control System. The advantage of parameterization via theProcess Control System is the simplification of device replacementsince no additional effort is required in addition to replacing the physicaldevice.

7.1 Built-In-Slave (BIS) Description

The Gateway has an integrated slave (Built-In-Slave or "BIS“) with a DPaddress that can be configured with the DIP switch on the Motherboard.As a device participating in cyclic data exchange, the BIS returnsfunction monitoring and diagnostic data to the Master.

7.1.1 Cyclic Data Exchange

The BIS is a modular DPV1 slave with one slot. Two modules are avail-able, each with a one-byte input and one-byte output. The input pro-vides a combined status message for the Gateway. The status messageis coded as a PA Profile Status Byte (0x80: Good; 0x00: Bad). A dummybyte (0x00) must be sent as an output data item.

7.1.2 Parameterization Options

The two possible modules are:

• the default module and• the PA-BUS configuration module.

The following values can be parameterized with the PA bus configurati-on module:• Watchdog time• Retry limits• Number of active PA segments

7.1.3 Diagnostics (Slave Diagnostics)

The BIS returns two diagnostic blocks described in the GSD:

• Device Diagnostics and• 0- 4 x Channel Diagnostics.

Device Diagnostics provides specific diagnostic information about theGateway. This information is parsed directly by the Process Control Sy-stem and displayed for the user. In redundant configuration, all diagno-stics information is also available for the redundancy partner. DeviceDiagnostics includes:

All Device Diagnostic parameters identified by * cause the "Ext_Diag“bit to be set in System Diagnostics. The Process Control System thenmarks that slave as defective.

Channel Diagnostics returns specific diagnostic information about eachindividual segment. These error messages are prioritized and set topreferred by the BIS depending on their ranking. The following table re-presents diagnostic information according to its ranking.

If the PA bus configuration module is set, values that are set with this mo-dule cannot be changed with acyclic access during cyclic communicati-on.

7.2 Coupled Slaves

This section applies to coupled slaves on non-redundant Masters andto Flying Redundancy Masters.

All coupled PA slaves behave as non-redundant DP slaves after theGSD conversion.

Both cyclic and acyclic communication is coupled.

As many C2 connections are coupled to the slaves as they support, al-together a maximum of 500.

From the Master's point of view, a change in redundancy of the Gatewayhas no effect on PA slaves. They do not drop out of communication.

The FREEZE and SYNC modes are coupled, but because DP commu-nication and PA communication are incompatible in terms of time, theyare not relevant for practical purposes.

7.3 Acyclic Data Exchange with BIS via DTM

The BIS supports four acyclic connections. Three dialogs are availablein acyclic mode via the DTM (Device Type Manager):• the Offline Dialog• the Online Dialog• the Diagnostics Dialog

In the Offline dialog, all parameters can be set locally without having anydirect effect on communication or the device. Data can be written to thedevice after all settings have been made. Current parameters can alsobe read in from the device, processed and saved.

7.4 Redundant Operation

7.4.1 Redundancy Behavior

During redundant operation, the Gateway simulates PA slaves for theDP-BUS. From the point of view of the DP bus, Redundancy Switchoverhas no visible effect on the Master. All slaves remain in the cycle. ThisTransparent Redundancy (TR) differs from normal Flying Redundancy(FR) behavior, which allows slaves to drop out of the cycle for a definedtime.

The HD2-GTR-4PA supports all Masters that work on the Flying Redun-dancy principle as well as all non-redundant Masters.

The BIS automatically detects whether the DP master is using a redun-dancy concept. If the DP master is working according to the Flying Red-undancy concept, the Gateway automatically adjusts itself accordingly.No settings of any kind need to be made.

With Transparent Redundancy, exchange of user data remains intact. Inthe worst case, only non-critical acyclic data exchange will drop out.

7.4.2 System Environment for Redundant Operation

In redundant operation, both BISs (Primary and Backup Gateway)should be in cyclic data exchange. Assigning bus addresses to both Ga-teways makes it easy to monitor both BISs with the Master, which de-tects the failure of one of the two BISs and reports the relevant slaveaddress.

The PROFIBUS Power Hub provides redundant Coupling of PA seg-ments in the following system environments:

• with use of non-redundant Master and• in a Flying Redundancy system.

Non-redundant Masters do not see any effect on PA slaves from Red-undancy Switchover. The Backup Gateway takes over communicationseamlessly. Both Gateways participate in general Token Ring operation:Primary Gateway = PA Master Address 1, Backup Gateway = PA MasterAddress 2. Participation in Token Ring operation thus allows use ofhandhelds for diagnostic purposes.

The BIS must participate in cyclic data exchange.

In the FR environment all PA slaves are configurated as normal non-red-undant slaves. The BIS can be configurated as an FR slave. For addi-tional information, see chapter “Redundancy Concepts” on page 73.

Figure 7.4: Integration into Flying Redundancy and non-redundant system

7.4.3 Applications with Redundant Operation

Redundancy is available if:

• both Gateways are in operation with no errors• both Gateways detect DP baudrates and• there are no errors in PA communication.

Possible reasons for Redundancy Switchover are:

• Hardware error in the primary Gateway.• Loss of baudrate (cable break, etc.).• BIS drops out of the cycle (because of an unlock from the Ma-

ster or the Watchdog time has expired, etc.).

Redundancy Switching has taken place if:

• both BISs have dropped out of communication and• the primary BIS comes up again on the bus immediately or• the BISs on the DP-BUS have changed roles.

The Primary Gateway is identifiable by:• its LED „Red.“ (Redundancy) is flashing or being lit.

If a Backup Gateway is plugged into the Motherboard:

10.1 Redundancy Concepts

10.1.1 Overview

Two redundancy concepts have become established on the market:Flying Redundancy and System Redundancy. These redundancy im-plementations are described below.

10.1.2 Flying Redundancy

Under this concept, both slave and master instances are connected tothe same physical bus so there is only one DP cycle. The Address of thePrimary Slave incremented by 64 is assigned to the Backup Slave:

•

Figure 10.1: Flying Redundancy

This concept involves the disadvantage that in the event of a fault on thebus, all communication is interrupted. If Redundancy Link Modules(RLM) are used, this can be avoided by means of so-called Media Red-undancy. As the following topology illustrates, a fault is only relevant tothe corresponding bus:

This structure represents a common "Flying Redundancy“ concept. Itdemonstrates that the Primary Slave and Backup Slave do not need tobe connected to the same physical bus.

10.1.3 System Redundancy

Under the concept of "System Redundancy" there are two Masters,each one of which performs its own PROFIBUS cycle on two differentlines. The redundant Slave instances are connected to each other withthe corresponding cables:

•

Figure 10.3: System Redundancy

The main disadvantage of this concept is that non-redundant Slavescan only be used if Y-Links are also used. System Redundancy isusually found in combination with the Siemens S7. The Pepperl+Fuchs HD2-GTR-4PA Gateway does not support "SystemRedundancy".

Current, Voltage and Power in an in-trinsically safe circuit are so low that ignition cannot take place in case of short circuit, circuit breakage or earth leakage. Intrinsically safe devices can be removed from or added to circuits during operation.

12.1 How CREST Works

• The original specification draft for Fieldbus (SP 50) suggested the use of simple passive conditioners and a common grounded bulk po-wer supply.

• The grounded earth eliminated pro-blems of cross-talk and noise, but introduced other problems, such as impedance loss and/or unbalance, if a pole of a segment was shorted to ground.

• To combat this potential problem, galvanic isolation was introduced to each segment in the form of a DC-to-DC converter.

This led to the use of a current compensated choke to simulate AC orsignal isolation. Cross talk is reduced to acceptable levels and CRESTcan realise a significant reduction in segment cost when using non-iso-lated segments. This method has also been applied to isolated FieldbusPower Supplies to significantly reduce the effect of EMI/RFI emissions/receptions as well as the effects of network unbalance and harmonic ornatural resonance.

'Pure or ideal isolation' is never attained in modern-day switching-modepower supplies as they usually have a high voltage capacitor across thegalvanic isolation barrier that, by virtue of reducing output ripple andEMI/RFI emissions for itself, prevents them from achieving 'ideal' isola-

• With segment isolation, cross-talk is reduced, and grounded seg-ments will not cause impedance problems.Unfortuanately, often a EMC filter capacitor is used across the galva-nic isolation to reduce EMI/RFI emissions and output ripple, effec-tively offering a low impedance path for high frequency signals.

• The engineers at Pepperl+Fuchs studied the model and realised that if the supply isolation was turned by 90 degrees, then galvanic isolation could be emulated whilst creating a high impedance common mode and differential noise filter.

tion. The figure below shows the capacitor, used on switching-mode po-wer supplies to reduce radiated noise.

•

The parasitic filter capacitor bypasses the 'effect' of AC isolation, ma-king the segment isolation less than ideal. Compensation for the loss ofisolation is achieved by using a common mode inductor (CREST).

The common mode inductor converts differential mode noise into com-mon mode noise, which is not affecting bus communication any more.

The common mode inductor is specially designed to operate within thefrequency range specific to Fieldbus. Although there are small commonmode inductors used at the input stages within DC-DC converters, theyare only sized for frequencies beyond those that are important to Field-bus.

The common mode inductor is also used for high impedance isolationwithin the Fieldbus frequency spectrum, to effectively isolate any poten-tial resonance effect or influence that may be caused by the bulk powersupply. Otherwise this type of resonance could distort the communica-tion signal and lead to communication failure.

12.2 NON-ISOLATION with CREST – the Definitive Solution?

Although this appears to be an ideal solution, the current compensatedchoke can easily be saturated if one pole or one segment is shorted to

earth and, at the same time, another pole on another segment (sharingthe same bulk power supply) is shorted to earth.

•

Of course, even with galvanic isolation, this could happen with a pole-to-pole fault on two segments – i. e. a similar two-fault situation.

Increased safety = increased integrity

With good wiring practice and use of high integrity components found inincreased safety and type n installations, a pole-to-pole fault and pole-to-shield fault are very unlikely to occur. Fieldbus segments are usuallyconnected in a trunk configuration whereby the trunk is connected to aSegment Protector or a FieldBarrier to increase the integrity whilemaintaining field devices. Once installed, the trunk wiring will most likelynever be worked on, making any dual pole-to-pole or pole-to-groundfault very unlikely.

With routine maintenance, as requested by all Fieldbus component sup-pliers and safety authorities, non-isolation with CREST can realize avery robust low cost alternative to galvanically isolated segments.

For high integrity networks, where cabling is not controlled or adequa-tely maintained, isolated Fieldbus Power Supplies should be consideredas an alternative to non-isolated Power Conditioners.
