IntroductionThis catalog contains information about the Profibus PA and Foundation Fieldbus network and has the main goal to show thejunction box line for the field instrument. The junction box in this catalog can be passive, with protection against short-circuit orintrinsic safety barrier to protection for up to 8 Ex I field equipment and are available in plastic or metallic material.

Profibus PA and Foundation Fieldbus H1With fieldbus technology, users can have several benefits offered by digital technology and also they can take advantage and getoptimization and cost savings with the network distribution bringing safety and reliability in the operations. For the success of any automation and control network, the installation should be done carefully and within the specifications.Precautions and practices are required when designing, installing or testing Profibus PA networks and also adopted for theFoundation Fiedbus H1 network, since the physical layer of these protocols are defined by the same international standardIEC61158-2.

The Profibus PA and Foundation Fieldbus H1 protocol is a bi-directional digital communication that allows the networkinterconnection of several equipment in the field, doing acquisition execution and functions, as well as the procedures andmonitoring stations (IHMs) through supervisor softwares. The protocol is based on OSI standard, which has the following layers:Physical Layer, Communication Stack and User Application. We can mention the management in a global way with the applicationsand advent models based on Function Blocks and Device Descriptions, which recently was standardized according to IEC, the EDDL concept including HART, Foundation Fieldbus and Profibus. The Physical Layer is defined by international standards (IEC, ISA). It receives messages from the Communication Stack andconverts them into physical signals in the middle of the fieldbus transmission including and removing preambles, delimiters ofbeginning and end of messages.

The physical layer is based on the IEC61158-2, we can cite the following features:

• Data transfer using Manchester code with transmission rate 31.25Kbit / s

• For a full signal communication, each product must have at least 9 volts. The H1 physical layer allows that the fieldequipment is powered by bus. The same pair of wires that feed the equipment also provides the communication signal.

• Maximum length is 1900m (trunk and spurs) without repeaters.

• Using up to 4 repeaters, the maximum length can be 9.5 km.

• Non safety buses in Profibus PA and no external power for trunk line can support the communication of 2 to 32connected field equipment.

• Profibus PA trunk must be able to support various equipments in accordance with intrinsic safety standards and withoutexternal power: - Explosion Group IIC: 9 equipments - Explosion Group IIB: 23 equipments Note: It can connect more equipments than the specified, depending on the equipment consumption, the power supply, the intrinsic safety barrier characteristics and the FISCO model.

• No interrupting trunk line in operation while connection and disconnection equipments on the spurs.

• Topology: bus, tree, star or mixed (a combination of all supported technologies).

The FISCO model has the following features:

a) a single active element (power supply) on the Fieldbus, located in non-classified area; b) the others equipments are in classified area; c) each field equipment must have minimum consumption of 10mA; d) in Ex ia areas the maximum bus length must be 1000m and 1000m in Ex ib areas; e) For the cable (no cabling restriction until 1000) must take the following parameters:- R´:15 ... 150 Ohm/Km- L´: 0.4 ... 1 mH/Km- C´: 80 ... 200 nF/KmCable type A: 0.8mm2(AWG18) (*)

f) Termination:a. R = 90 ... 100 ohmsb. C = 0 ... 2.2 µF.

Physical Layer

The FISCO concept was optimized allowing a greater number of the field equipments, according to the bus length, taking intoaccount the cable variation parameters (R, ‘L’, C ‘) and using terminators. The concept is in accordance with gases categories andgroups that make a simple evaluation of the complete installation involving intrinsic safety. This increased the current capability per segment and the evaluation for users became easier. Furthermore, when purchasing certified products they don't have to worry with calculations, even changing them in operation.

Fieldbus signal in voltage mode Manchester code

The data transmission of a field equipment is typically 10mA in 31.25Kbit / s at an equivalent resistive load of 50 Ohms creating amodulated voltage signal in 1.0 Volt peak to peak. The power supply can provide 9 to 32 VDC, but in secure applications (IS) it´snecessary to follow the intrinsic safety barriers requirements.

The total cable length is the sum of the trunk length (bus master) and all the Spurs (larger than 1m) which the maximum length ofthe cable type A (*) is the 1900m in unsafe areas. In safe areas the maximum length is 1000 m using cable type A and the spurscannot exceed 30m.

Network CablesSeveral cable types can be used (it is recommended to use the twisted-pair with the shield). The maximum length can changedepending on the diameter and others cable components. Below we show four cable types, but there are more options. No specialcable type is required. Usually the cables that connect the instruments can be used for the trunk line. The network cable forProfibus PA and Foundation Fieldbus are produced by several manufacturers becoming easy the choice.

Cable Type A

Note: only the shield must be grounded, never the communication wires. If the cable has no shielding wire, it should be inside ametal conduit that works as a shield.

A spur is a branch off the trunk and can vary in length between 1 and 120m. Spurs length is basically independent of the cable typeand the total length can´t not exceeded the specifications, but depends on the amount of equipment connected in it. Never connect more than four devices on the spurs. The spurs are used to connect the equipments to the trunk so they can be removed withoutinterrupting the network operation.

Equipment x Spur lengthThe maximum segment length is the sum of the trunks and spurs lengths and the lengths less than 1 m are not considered spurs.The amount of spurs and the number of equipment should be in accordance with the table below.

Note 1: For Ex installations you should not exceed the 9 equipments in group IIC and the lengthshould be up to 30m with one equipment per spur and the consumption less than 110 mA.Note 2: It is important to pay attention to the spur length when using the star topology, sincethe Spurs in this case are often longer when compared with the bus line topology.

TerminadorThe terminator is designed tomatch the network impedance and for this must be installed onall edges of trunk line, so thereflection effect will beeliminated and the networkworks normally.

Intrinsic Safety DefinitionsThe intrinsic safety definition is a representative prevention concept of the ignition by power limiting of the incoming bus supply aswell as installation components in the field. The working principle is based on manipulating and storing electric low-power incapable of producing a detonation of the explosiveatmosphere due to heating effects or electrical sparks. In general it can be applied to several equipments and instrumentation systems, and the electric power only can be controlled atlow levels in instruments such as electronic current transmitters, pneumatic converters, limit switches, signaling, etc. The basicprinciple of the intrinsic safety is handle and storage low energy, so the circuit installed in the safe area never has enough energyrated (manipulated or stored) capable of causing ignition in the potentially explosive atmosphere. The great advantage of intrinsicsafety is to allow the instruments disconnection even energized.
