FieldBarrier 1 Introduction The FieldBarrier F*D0-FB-Ex4.*** and RD0-FB-Ex4 connect up to 4 intrinsically safe field devices. It is connected via non-intrinsically safe connections to the trunk of a fieldbus with a physical layer in accordance with IEC 61158-2. The FieldBarrier works exclusively on the physical layer, which makes it independent of the protocol. This allows it to be substituted for any field bus with a physical layer in accordance with IEC 61158-2.
FieldBarrier 2 Validity of these instruction manual This instruction manual descibes the following Pepperl+Fuchs products: • the FieldBarrier F2D0... for panel mounting in aluminum field housings. • The FieldBarrier RD0... for mounting on a 35-mm top hat section rail in accordance with EN 50 022. A corresponding declaration of conformity may be requested from the manufacturer.
FieldBarrier 3 Symbols used This symbol warns of a danger. In the event the warning is ignored, the consequences may range from personal injury to death or from damage to equipment to destruction. This symbol warns of a possible fault. Failure to observe the instructions given in this warning may result in the device and any facilities or systems connected to it developing a fault or even failing completely. 08/2007 122329 This symbol draws your attention to important information.
FieldBarrier 4 Instruction manual These instructions apply in conjunction with the respective data sheets. You can access the data sheets at www.pepperl-fuchs.com. The operator of the system bears the responsibility in terms of planning, mounting, commissioning, operation and maintenance, especially in conjunction with applications in areas subject to the danger of explosion.

FieldBarrier 4.5 Commissioning and installation The FieldBarrier may be installed according to its designation in Zones 1 and Zone 22 (non-conductive dust) . The Declaration of conformity must be observed. It is especially important to maintain any "Special conditions" that may be indicated. When installing intrinsically safe fieldbus segments, EN 60079-14/IEC 60079-14 must be observed. For the Federal Republic of Germany, the "National Foreword“ of DIN EN 60079-14/VDE 0165 Part 1 must also be observed.
FieldBarrier 4.5.1 Commissioning and installation of the F2D0-FB-Ex4.*** Only permanently laid cables and lines must be inserted into the cable glands. The screw plugs must only be replaced by cable glands who are adapted for the intended kind of use. By mounting the cable glands pay attention to the according instruction manual. For the permissible cable diameters, please refer to the respective data sheet.
FieldBarrier connection must be designed to prevent self locking and must be protected against corrosion. Protection against corrosion can also be achieved by using tinned cable plates, for example. The cover of the non-intrinsically safe fieldbus connection must only be removed when no electrical power is present. The connection of the non-intrinsically safe fieldbus connection must only be made when no electrical power is present. After that, the cover must be remounted.
FieldBarrier equalization (capacitive grounding of the shield of the trunk). This capacitor can be bypassed with terminals 1B and 2B (hard grounding of the shield of the trunk). If the shield of the EEx e fieldbus transmission line is grounded for reasons related to EMC, Section 12.2.2.3 of EN 60079-14 and Section 3.3.3 of the PNO introductory manual PROFIBUS PA or Sections 4.1 and 4.4 of the FOUNDATION Fieldbus Application Guides must always be observed.
FieldBarrier 5 General 5.1 Range of application of the FieldBarrier FieldBarriers can be used in combination with fieldbus systems that use the "Manchester Coding Bus Powered“ physical layout in accordance with IEC 61158-2. This includes the H1 bus of the FOUNDATION fieldbus and the PROFIBUS MBP, for example. FieldBarriers ensure galvanic isolation between a non-intrinsically safe and an intrinsically safe fieldbus segment.
FieldBarrier the advantage that fieldbus stations can be disconnected from or connected to the transmission line during ongoing operation. If a fieldbus segment is designed in Intrinsic Safety ignition protection type, proof of intrinsic safety must be provided. To make this proof of Intrinsic Safety as simple as possible, there are 2 different models: • the FISCO model • the Entity model Which of the two following models should be used is stipulated by national requirements and/or laws.
FieldBarrier C’ = C’conductor/conductor + C’conductor/shield if the shield is connected with a pole of the segment coupler/Power Link. 9. The bus segment must be terminated on both ends of the trunk with a fieldbus terminator. The fieldbus terminator must conform to the following limits: 90 Ω < R < 100 Ω 0 µF < C < 2.2 µF: Given the prerequisite that Points 1 through 9 are all satisfied, Proof of Intrinsic Safety has been provided by means of the FISCO model.
FieldBarrier 5.2.3 Topologies Fieldbus topologies are independent of whether an H1 fieldbus segment of the FOUNDATION fieldbus or a PROFIBUS MBP segment is being operated. PROFIBUS MBP(-IS) or H1 bus (IS) of the FOUNDATION fieldbus PROFIBUS DP or H1 bus of the FOUNDATION fieldbus Bus termination resistor Spur Spur Segment coupler or Power repeater Spur Trunk The basic layout of a fieldbus with FieldBarriers is illustrated in Figure 5.1. The use of FieldBarriers influences possible topologies.
FieldBarrier The recommended network expansion is equal to the sum of the trunk and all spurs. A fieldbus station works from an input voltage of 9 V, i. e. this value corresponds to the minimum input voltage. Please note the specifications of the FieldBarrier. For more detailed information, please refer to chapter 6.3. With an unfavorable distribution of stations, i.e.
FieldBarrier Following values applies especially for the FieldBarrier: The maximum cable length per output is limited to 120 meter and may be operated without terminators. The outputs meet the requirements of the IEC 60079-27. Number of communication members Maximum spur length 1 to 12 120 m 1 device per output 13 to 14 90 m 15 to 18 60 m Consider the master of the PROFIBUS Segment Coupler or the host card at FOUNDATION Fieldbus installations as communication members.
FieldBarrier If the shield is only applied on one side, EMC protection is less reliable. In this case as well, there is no need for the potential equalization conductor in the case of non Ex applications. 08/2007 122329 Pepperl+Fuchs always recommends the use of shielded lines for the fieldbus. The shield should be hard grounded on the segment coupler/ Power Repeater, FieldBarrier and on all field devices. Please note in this regard chapter 4.6.
FieldBarrier 6 Planning for a fieldbus application The following section explains how to perform planning for a fieldbus application in combination with the FieldBarrier. This planning is different in a few items • from planning without a FieldBarrier • depending on whether a FOUNDATION fieldbus or a PROFIBUS MBP application is being planned. Explicit mention is made of this in the corresponding places. 6.

FieldBarrier The cable length on an output can be up to 120 m and is operated without a fieldbus terminator. The outputs meet the requirements of both PTB Report W-53 (FISCO model) and the requirements of the Entity concept. For additional information on this subject, please refer to chapter 5.2.1 The technical data can be found in the data sheet.
FieldBarrier 6.2 Topologies in combination with the FieldBarrier Using the FieldBarrier affects the possible topologies of a fieldbus application. The physical layout used for the H1 bus of the FOUNDATION fieldbus or the PROFIBUS MBP allows for spurs with both Ex and non Ex applications. The permissible length of spurs depends on • the area of application (Ex or non Ex application; see also chapter 5.2.3). • the number of stations running on the trunk.
FieldBarrier 6.2.2 Topologies of the trunk in connection with the FieldBarrier Possibility 1: Daisy Chaining There are 2 possible topologies for the non-intrinsically safe trunk: l<1m 08/2007 122329 Possibility 2: Junction boxes l<1m Figure 6.3: Topologies of non-intrinsically safe fieldbus segment Subject to reasonable modifications due to technical advances.

FieldBarrier • By possibility 1, the trunk is directed into the FieldBarrier through one of the EEx e cable glands and back out through the second EEx e cable gland. • By possibility 2, the FieldBarrier is connected to the trunk via a junction box Care must be taken here that the connection line between the junction box and FieldBarrier is < 1 m. The transmitters integrated into the FieldBarrier are used to transfer impedances connected to the outputs to the trunk.
