1. STANDARD TOPOLOGIES – RULES AND CONSTRAINTS

1.1. Bit Rates

A WorldFIP network can operate at different bit rates: 31.25 kbits/s, 1 Mbit/s, 2.5 Mbits/s and 5 Mbits/s.

The following selection criteria may be applied:

A bit rate of ...

31.25 kbits/s

S 1 Mbit/s

S 2.5 Mbits/s

S 5 Mbits/s

is used to meet the needs of ...

S large–scale topologies

S topologies requiring easy wiring topologies with a total length limited to a few kilometres.

Remark

This bit rate provides applications with only a limited level of performance

Table 1.1 – Choice of Bit Rate According to Network Topology

1.2. Solutions using a Wire Medium

1.2.1. Topologies

The copper wire medium is the most economical and versatile wiring solution and is therefore the most widespread.

1.2.1.1. Bus Topology

Communication on a bus–based system works according to a principle whereby each subscriber (S) transmits and receives on the same shielded pair.

This bus topology can be used at any bit rate and is compulsory for bit rates of 1 Mbit/s, 2.5 Mbits/s and 5 Mbits/s.

The bus consists of a single–pair trunk cable which wraps round to each subscriber via a dual–pair drop cable. The branch device between the trunk cable and drop cable is known as a TAP.

Each end of the trunk cable is connected to a line termination (LT).

Figure 1.2 illustrates the function of the TAP and drop cable which are used to connect a subscriber to the trunk cable.

The trunk cable and drop cable have the same characteristic impedance which matches that of the line termination used. This principle guarantees optimised signal transmission between the different field bus subscribers and minimises parasitic reflections.

1.2.1.2. Free Topology

Communication on a free–topology system works according to a principle whereby subscribers can be connected to a set of twisted pairs and these pairs are then interconnected.

A free topology simplifies wiring and implements general–purpose connection boxes. However, it can only be used at a low bit rate, i.e. 31.25 kbits/s.

The bus is composed of a single–pair trunk cable to which single–pair connection leads are connected in parallel, via connection boxes, to link up subscribers. Each end of the trunk cable is connected to a line termination (LT).

The decision whether or not to install protective devices on connection leads must be applied uniformly to all network subscribers.

1.2.2. Connection

The connection to the trunk cable of a subscriber is generally permanent. For maintenance reasons, a connector has been installed, allowing disconnection of a local subscriber group in a cabinet, if necessary.

Figure 1.6 illustrates this connector.

ALS 50414 e–en WorldFIP: Design and Installation Manual Page 1–3

Design

Whatever the topology, a 9–pin SUB–D connector is generally used for this purpose. It is recommended to use:

D the 9–pin MicroSUB–D connector to meet miniaturisation requirements and

D the 4–pin circular connector to meet sealing requirements.

Figure 1.7 – Self–looping Connector for Wire Medium

Whatever the location of the connector, the global activity of the network must not be interrupted when a subscriber or subscriber group is disconnected. In the case of bus topologies, when a subscriber is disconnected at the TAP junction, the active self–looping mechanism inside the connector restores the continuity of the trunk cable within a guaranteed maximum time period compatible with the WorldFIP standard.

You may want to connect a monitoring unit. If so, you could do this by including, for example, one or two spare drop cables and subscriber connectors at strategic points.

Design

1.2.3. Distances

The design limits of a wire–medium architecture are determined by a number of basic rules.

Signal attenuation and signal distortion increase with the length of the cable and the number of subscribers on the bus.

These constraints can be overcome by using repeaters (R) which regenerate the signal waveform, in terms of amplitude and phase, throughout the nework.

Another constraint concerns the maximum propagation time between two network subscribers. This time is equal to the maximum propagation time of the electrical signal on the medium, plus the time required to cross the repeaters.

Note

In order to take into account the subscriber drop structure and the increased attenuation of drop cables, the total length of a wire segment is calculated using the following formula:

Total segment length = (length of trunk cable + (3 * (length of drop cables)).

This data is guaranteed for the following conditions of use: FIELDRIVE +

Note

These characteristics ensure compatibility with standard IEC 61158–2 and are based on the assumption that:

S there is only one subscriber per drop,

S these lengths are reduced by 30 m for each additional subscriber connected.

In order to take into account the subscriber drop structure, the total length of a wire segment is calculated using the following formula:

Total segment length = total length of trunk cable + 240 m (i.e. two maximum lengths of a connection lead).

This data is guaranteed for the following conditions of use: FIELDRIVE +

FIELDTR transceiver, FIP DEVICE MANAGER basic software V4.5 or later and MICROFIP HANDLER basic software V1.3 or later.

1.3. Solutions Using a Multimode Optical Medium

1.3.1. Topologies

The multimode optical medium offers similar performance to the wire medium in terms of total length. It is ideal for applications in which the fieldbus crosses industrial facilities where electrical noise levels are high or where ground potentials are not uniform throughout the site.

Fully optical network installations are designed with a star topology as this type of medium demands point–to–point connections.

Subscribers (S) are connected around the edge of the optical network and data is exchanged via one or more active optical stars (AOS). Optical links are created between subscribers (S), equipped with an optical coupler, and optical stars (AOS), as well as between optical stars (AOS).

ALS 50414 e–en WorldFIP: Design and Installation Manual Page 1–7

Design

1.3.2. Distances

The design limits of an architecture based on the use of a multimode optical medium are determined by the same rules as those applicable to a wire–based architecture.

As with architectures using a wire medium, the maximum propagation time of the signal between two subscribers is limited. In this type of architecture, this limit is equal to the signal propagation time on the multimode optical medium, plus the time required to cross the active optical stars (AOS).

Another constraint, in this case specific to optical architectures, is the maximum propagation time of the signal between subscribers (S) and active optical stars (AOS).

1.4. Solutions Using a Single–mode Optical Medium

The single–mode optical medium provides greatly improved performance in terms of total length compared to wire and multimode optical media, while offering the same advantages as multimode optical fibre for industrial facilities where electrical noise levels are high or where ground potentials are not uniform throughout the site.

This type of medium is used only in making optical fibre sections within mixed topologies where, depending on the characteristics of the fibre used, it can offer total lengths of up to 45 km without a repeater.

Page 1–8 WorldFIP: Design and Installation Manual ALS 50414 e–en

Design

1.5. Solutions Using Mixed Media

1.5.1. Topologies

Topologies are more generally designed combining different types of wire and multimode and/or single–mode medium within a global architecture in order to meet all requirements more effectively and at lower costs.

Mixed repeaters (MR) and active mixed stars (AMS) are used to implement this mixed technology. Mixed technology can be used effectively to combine the noise immunity offered by optical fibre with the lower costs offered by copper networks.

2. DESIGN OPTIONS

2.1. Medium Redundancy

When designing a network architecture with medium redundancy, each component of the physical layer must be duplicated to minimise the risk of damage to the network in the event of an incident.

The duplicated components include the connectors of each subscriber (S), cables, TAPs, line terminations (LT), repeaters (WR, OR, MR) and active stars (AOR, AMR).

The WorldFIP interfaces (subscribers) supporting medium redundancy can also be used in single–medium architectures by using only one of the two connectors.

Wherever possible, all components used to ensure redundancy of the physical layer must be physically separated to avoid any simultaneous material damage.

If the medium redundancy strategy is adopted, the entire network must be designed according to redundancy principles: all the subscribers (S) must be equipped with a coupling device designed to manage medium redundancy.

2.2. Powering via the Bus

2.2.1. Bus Powering on the Signal Pair

The relevant standards define the possible use of bus–powered devices. This type of device consumes the power it requires on the network. The pair of wires carrying the information signal of the fieldbus also conveys a DC voltage to provide power to subscribers.

This technique is referred to as “bus powering on the signal pair”. The power supply voltage range on the bus is between 9 and 32 VDC (always direct–current power supplies).

In this type of architecture, the fieldbus can include bus–powered subscribers as well as standalone devices.

Bus–powered subscribers are generally sensors and actuators. Most ALSTOM devices are standalone devices.

ALSTOM subscribers can, however, be used on networks with the “bus powering on the signal pair” option, as the fieldbus runs across a series capacitor which provides protection against the DC voltage on the signal pair.

2.2.2. Bus Powering on a Dedicated Pair

This option is not included in the standards but is nevertheless used in standard versions of ALSTOM architectures.

This option uses trunk cables (and possibly drop cables) containing a pair dedicated to the power supply voltage

(always a DC power supply) in addition to the pair(s) conveying the information signal of the fieldbus.

When the “bus powering on the signal pair” option is used specifically for remote powering of repeaters (WR, MR), the power supply voltage pair may only be implemented in the trunk cable. Repeaters have low power consumption and cable resistance requirements do not constitute a constraint. In this case, the standard IBM 1A cable can be used: one pair conveys the information signal of the fieldbus and the other pair conveys the power supply voltage to the repeater.

The small cross–sectional area of an IBM 1A cable (AWG 22) considerably restricts the possibility to supply power via the bus – the characteristic resistance of the cable is 65 ohms/meter. When defining networks which are incompatible with IBM 1A cable constraints, the cable must be selected defining the cross–sectional area of the pair of wires dedicated to the power supply voltage.

The voltage transmitted on the dedicated pair is 24 V +/–20% or 48 V +/–20% at the power supply source.

2.3. Grounding

The ground plane of an electrical system is designed to guarantee:

D the safety of personnel,

D the protection of sensitive devices and system facilities.

The ground plane is composed of a permanent ground connection which cannot be disconnected. It has a sufficiently low impedance and adequate carrying current to avoid any increase in voltage liable to present a risk for connected equipment or for personnel.

The ground plane is also referred to as the equipotential ground plane as it is designed to eliminate excessive differences in potential between two elements adjacent to the plane.

The ground connections of a WorldFIP network must comply with provisions relating to:

D the EMC directive,

D electrical shocks.

In theory, these two categories of provision are complementary since they are both aimed at equalising potential.

ALS 50414 e–en WorldFIP: Design and Installation Manual Page 1–15

Design

The standard technique used is to ground the shielding of the fieldbus cable at one point of the trunk cable of each segment.

This is why most devices (e.g. subscribers (S), active stars (AMS or AOS), repeaters (WR, MR), TAPs), especially devices manufactured by ALSTOM, provide for direct–current isolation between the cable shielding and ground.

Furthermore, the direct connection between the fieldbus cable and ground can be located in a TAP device.

Creating a capacitive coupling between the shielding of the fieldbus cable and the local ground of each process device

(subscribers (S), active stars (AMS or AOS), repeaters (WR, MR), TAPs) is considered a standard technique. The coupling in question is obtained using a sub–assembly made up of a capacitor and varistor located in the device (S).

2.3.1. Networks with an Equipotential Ground Plane

A network based on a uniform ground plane, in compliance with standards IEC 60364–4 and IEC 60364–5, can be defined as a network with a single ground plane.

The standard technique recommended in the standard physical layer and summed up above should be used whenever possible:

D connect a device (a TAP) on the length of cable directly to ground and

D couple the other devices to ground via a capacitor.

If the network requires devices for which there is no choice other than direct grounding, you can use the following architecture in which each process device is grounded directly. The designer may also opt for a mixed approach using some devices which are directly grounded and others with a capacitive ground connection.

2.3.2. Networks with no Equipotential Ground Plane

When designing a fieldbus type network covering several installations, it is sometimes impossible to create a uniform ground plane for the entire network.

Under these conditions, a DC connection between the shielding of the field bus cable and the local ground of several devices located in different buildings or installations would generate noise currents in the shielding, owing to the difference in potential between the local grounds of the devices.

In this case, it is strongly recommended to implement standard DC isolation on all the devices except one (connected directly), together with a capacitive coupling to the ground of the cable shielding.

Another technique, recommended when the field bus covers several installations with high possible voltage differences on the corresponding ground planes, is to use mixed repeaters (MR) connected by an optical segment.

This technique also offers another advantage in terms of safety, because a permanent connection to the local ground is included in each installation.

3.6. DCTAP Daisy Chain Connector

A DCTAP device can be used when environmental conditions allow the use of IP 20 compatible products.

The DCTAP is designed to combine in a single device the functions of a TAP with those of a subscriber connector

(9–pin SUB–D). In this case, the DCTAP is connected directly to the trunk cable.

This connector is approved subject to the following remarks:

IBM 1A dual–pair trunk cables cannot be used with DCTAP connectors (their cross–sectional area is too large and they are not flexible enough). It is recommended to use a trunk cable with a single dedicated pair (see

Subsection 3.1.) for daisy chain connection to the DCTAP.

The other solution, considered as a standard, is to create subscriber drops made up of a TAP device, a drop cable and a dedicated subscriber connector. This solution is also considered more effective.

In the second case, the DCTAP device can be used as a subscriber connector, compatible with the standard 9–pin

SUB–D connector. This method is approved on systems when used in conjunction with recommended IBM 6A drop cables.

The cable exits the connector at a 45

° angle with respect to horizontal so as to minimise the space required when the equipment is installed in a cabinet.

This product is manufactured by ALSTOM.

3.13. Daisy Chains: Prewired Solution for Local Areas

Daisy chain products are dedicated to wiring several subscribers in a given local area. This type of product is used mainly for the internal wiring of cabinets.

A number of standard local wiring requirements have been identified and the use of these standard subassemblies optimises costs.

On the basis of these standard approved solutions, the network designer can define more daisy chains distinguished mainly by their dimensions (number of subscribers, length between micro–TAP couplers and the length between micro–TAP couplers and subscribers) and by whether or not they can be used in conjunction with line terminations.

In view of these considerations, a daisy chain arrangement can be summed up in a panel containing the items shown in the figure below:

The active stars in the second–generation OP130 product range offer several options.

OP130 active stars are modular signal regeneration devices designed mainly to connect multimode optical fibres, though they can also be used to connect wire media. The connection capacity of these stars depends on the choice of rack and on the type of board.

An active star is composed of several standard units (100 x 160 mm EUROPE format) assembled in a rack of the following dimensions:

19” x 3U x 290 mm rack or

4” x 3 U x 290 mm mini–rack.

The star is made up of modules that can be equipped with one or two copper or multimode optical transceivers so that the configuration may be adapted to meet requirements.

6. ADVANCED TOPOLOGIES

This paragraph is intended for network designers with specific requirements who cannot observe the standard topological rules defined in Section 1.

The detailed formula used to calculate the network topology is indicated below and takes into consideration the relevant characteristics of the devices making up the network link.

The length and maximum number of subscribers of a segment depend on the constraints described in Section 1.

The following calculation applies to the rules for defining the total distance of the network and indicates the best way to combine repeaters and optical stars when connecting standard network segments:

D the propagation time Tp between two subscribers of a network has a maximum value of Tpmax as shown below:

Tpmax

57 Tbits

58 Tbits

70 Tbits

Bit Rate

31.25 kbits/s

1 Mbit/s

2.5 Mbits/s

D the propagation time of the information signal on a copper or optical medium is as follows:

Tpco = Tpopt = 5

µs/km

D owing to the structure of drop cables, the distances covered by drop cables forming the drops must be multiplied by 3,

D the maximum propagation time between RP131 repeaters is as follows:

The propagation time between...

wire repeaters mixed repeaters optical repeaters

referred to as...

Tr_WR

2.5 Tbits

D the maximum propagation time between OP130 active stars is as follows:

Tr_AS_OO

equals...

3 Tbits

2 Tbits

0.5 Tbits

ALS 50414 e–en WorldFIP: Design and Installation Manual Page 1–35

Design

The complete formula can thus be summed up as follows:

Tp =

(length of wire trunk cable * Tpco)

+ (3 * length of wire drop cable * Tpco)

+ (length of optical fibre cable * Tpopt)

+ (number of intermediate repeaters * (Tr_WR, Tr_MR or Tr_OR))

+ (number of intermediate active stars * (Tr_AS_WW, Tr_AS_WO or Tr_AS_OO))

(If you use this formula, the number of repeaters or intermediate active stars may be greater.)

ALSTOM/CMF for a specific architecture definition study.

Installation

1. CHECK LIST

The following points must be defined during the network design phase before starting installation itself:

Network topology

Topological characteristics must be identified and must comply with the design rules set out in Chapter 1. The location of the different devices making up the network must also be defined. These devices include: subscribers, cables, connectors, TAPs, repeaters and active stars.

Environmental conditions

The characteristics of each device must satisfy environmental installation constraints regarding the following points: temperature range, EMC protection, IP protection required, etc.

Grounding strategy

The ground plane of the installation must be defined, as indicated in Chapter 1, Subsection 2.3.

Manuals

You should always read the user reference manuals relating to the equipment so as to follow installation instructions closely.

Wiring and checking tools

You should give preference to the wiring and checking tools recommended by equipment manufacturers.

Technologies

Technicians involved in optical technology should have the necessary qualifications and use the very latest techniques and solutions available in this field.

ALS 50414 e–en WorldFIP: Design and Installation Manual Page 2–1

Installation

2. ESSENTIAL RULES

Wiring quality depends on three main factors:

The passive and active items making up the network must have been designed and approved with respect to the

EMC recommendations corresponding to the EMC severity level demanded by the factory.

Choose wiring solutions offering the right EMC qualification level.

Particular attention is required for signal conductor connections. The reliability of the entire automation process depends on the quality of the installation of the physical layer.

A defective “signal” conductor connection, at any point of the field bus network, will lead to an interruption in global communication either immediately or following installation. Furthermore, it is always more difficult to locate possible failures on a field bus type network than on an architecture based on point–to–point links.

Take care when handling “signal” conductor connections.

Grounding is the last critical problem relating to wiring.

Cables, connectors and devices (TAPs, repeaters, active stars, subscribers) must be correctly grounded to guarantee the safety of personnel and ensure the reliability of the network with respect to electrical noise.

Low–impedance ground connections must be made and priority must be given to the total shielding of all wiring items. Incorrect grounding at any given point of the field bus network will affect the performance of the entire network.

The quality of ground connections guarantees the safety of personnel and the performance of automation processes.

Installation

3. WIRING VERIFICATION PROCEDURE

The wiring verification strategy is described below, step by step. It is easier to carry out a detailed check of wiring at the local level than to check the entire network from the beginning.

Moreover, the tools used to carry out checks on the global network are more sophisticated than the standard ohmmeter, especially when the network includes repeaters and active stars.

Wire connections. Local verification using an ohmmeter.

Verification of optical wiring is not addressed in this document. Refer to the relevant specific technical instructions concerning this subject.

An ohmmeter can be used to check the quality of a subscriber connection between the TAP and the subscriber as well as the local wiring located in a cabinet. Connection polarity must be checked.

Caution

Field bus networks are sensitive to the polarity of bus connections.

Check continuity along a given conductor path and check the insulation between several conductors or between the conductors and the cable shielding. You can carry out these checks in a given local area before reconnecting the removed line terminations and disconnected subscribers to the field bus.

Wire connections. Global verification of each segment using test plugs, an ohmmeter, portable oscilloscope and FIP wiring test set.

The verification of optical wiring is not addressed in this document. Refer to the relevant specific technical instructions concerning this subject.

During the global verification of the wiring system, each segment must be checked individually.

A simple ohmmeter cannot be used to check a segment stretching over several kilometres.

ALS 50414 e–en WorldFIP: Design and Installation Manual Page 2–3

Installation

You may adopt the following method to test a wiring installation:

D leave all the subscribers disconnected

D connect the line terminations (LT) to each end of the segment

D apply a DC voltage (e.g. 9 V with battery) to a subscriber connection via a dedicated connector. Check all the other connectors (using an ohmmeter) to ensure that the polarity is correct and that there is no residual voltage on the shielding.

D then apply a square–wave signal (e.g. coming from a device based on a 1 MHz CMOS oscillator) to a subscriber connection via a dedicated connector. The square–wave signal can be analysed upon reception using a portable oscilloscope at all the other connectors. The attenuation of the initial square–wave test signal can be compared to the attenuation of the field bus cable (typically 15 dB/km on a TRUNK cable).

Verification of the global network, comprising several segments, repeaters and active stars

At this stage, each segment should have been previously checked and declared satisfactory.

The repeaters and active stars can only propagate valid WorldFIP protocol frames, recognised as belonging to correct start–of–frame and end–of–frame sequences (these specific signal sequences are detected, checked and regenerated by the repeaters and active stars).

For this reason, the test input signal can no longer be supplied by a simple measuring oscillator. Instead, a WorldFIP station must regenerate the test signal. This measuring station must be equipped with a Bus Arbiter (BA) in order to communicate with the network.

It is recommended that the global network test be carried out with a measuring station equipped with the Bus Arbiter

(BA) on one segment and that data exchanges take place with one or more dual stations connected to all the other stations.

On installations with a redundant medium, the global verification of the wiring should first be carried out on each medium individually (with the dual–medium connectors disconnected), then with both media in operation.

Page 2–4 WorldFIP: Design and Installation Manual ALS 50414 e–en

Installation

4. QUALITY FACTORS

Once all the wiring has been thoroughly checked, the installation can be considered ready for use.

The following indicators may be used for the final verification:

Physical transmission error rate

This parameter is available on a WorldFIP subscriber (e.g. a FIPACCESS station or a FIPSPY) and is used to control frame flags, the Manchester code and the frame check sequences of incoming frames.

In order to meet the required error rate, the physical transmission error rate can be verified by checking continuous exchanges on the field bus; a value of 20 minutes without error should be obtained.

List of current subscribers

A list of current subscribers can be provided by the subscriber supporting the bus arbiter function. This list contains all the subscribers which have exchanged a valid “presence” variable with the station supporting the bus arbiter function.

This verification is easy to carry out if the bus arbiter function is performed by a station equipped with FIPACCESS.

This verification is also useful as the “presence” data item implements a significant part of the field bus processing capability; this presence is controlled on both media in a redundant–medium installation, thus allowing a specific test to be performed for each medium.

Subscriber identification

The station supporting the bus arbiter function can collect identification variables from different subscribers and thus obtain information concerning each subscriber.

Identification variables can be collected easily using a station equipped with FIPACCESS software.
