PROFIBUS NETWORKS 1.1 Local Area Networks in Manufacturing and Process Automation 1.1.1 General Introduction Communication Systems The performance of control systems is no longer simply determined by the programmable logic controllers, but also to a great extent by the environment in which they are located. Apart from plant visualization, operating and monitoring, this also means a high-performance communication system.
PROFIBUS NETWORKS SIMATIC NET With SIMATIC NET, Siemens provides an open, heterogeneous communication system for various levels of process automation in an industrial environment. The SIMATIC NET communication systems are based on national and international standards according to the ISO/OSI reference model.

Topologies of SIMATIC NET PROFIBUS Networks Connecting Segments Using RS-485 Repeaters By using RS-485 repeaters, segments can be interconnected. The RS-485 repeater amplifies the data signals on the LAN cables. You require an RS-485 repeater when you want to attach more than 32 nodes to a network or when the permitted segment length is exceeded. A maximum of 9 repeaters can be used between any two nodes.

Topologies of SIMATIC NET PROFIBUS Networks 2.2.1 Topology with Integrated Optical Interfaces The optical PROFIBUS network with nodes having an integrated FO interface is structured as a bus topology. The PROFIBUS nodes are interconnected in pairs by duplex fiber-optic cables. Up to 32 PROFIBUS nodes with integrated FO interfaces can be connected in series in an optical PROFIBUS network.
Topologies of SIMATIC NET PROFIBUS Networks PROFIBUS Optical Bus Terminal (OBT) Using a PROFIBUS optical bus terminal (OBT), an individual PROFIBUS node without an integrated FO port or a PROFIBUS RS-485 segment can be attached to the optical PROFIBUS network (see Figure 2-2 ). The attachment is made to the RS-485 interface of the OBT using a PROFIBUS cable or a preassembled connecting cable. The OBT is included in the optical PROFIBUS bus via the FO interface. 2.2.
Topologies of SIMATIC NET PROFIBUS Networks Bus Topologies Figure 2-3 shows a typical example of a bus topology In a bus structure, the individual SIMATIC NET PROFIBUS OLMs are connected together in pairs by duplex fiber-optic cables. At the start and end of a bus, OLMs with one optical channel are adequate, in between, OLMs with two optical channels are required. The DTEs are attached to the electrical interfaces of the OLMs.
Topologies of SIMATIC NET PROFIBUS Networks Star Topologies with OLMs Several optical link modules are grouped together to form a star coupler via a bus connection of the RS-485 interfaces. This RS-485 connection allows the attachment of further DTEs until the maximum permitted number of 32 bus attachments per segment is reached.
Topologies of SIMATIC NET PROFIBUS Networks Monitoring FO Links Using the echo function, the connected OLMs can monitor the fiber-optic sections. A break on a link is indicated by a display LED and by the signaling contact responding. Even if only one transmission direction is lost, the segmentation triggered by the monitoring function leads to safe disconnection of the OLM from the star coupler. The remaining network can continue to work without problems.
Topologies of SIMATIC NET PROFIBUS Networks A break on a fiber-optic cable between two modules is detected by the modules and the network is reconfigured to form an optical bus. The entire network remains operational. If a module fails, only the DTEs or electrical segments attached to the module are separated from the ring; the remaining network remains operational as a bus. The problem is indicated by LEDs on the modules involved and by their signaling contacts.
Topologies of SIMATIC NET PROFIBUS Networks Alternative Cabling Strategy If the distance between two OLMs turns out to be too long, a structure as shown in Figure 2-6 can be implemented.
Topologies of SIMATIC NET PROFIBUS Networks 2.2.3 Combination of Integrated Optical Interfaces and OLMs Note The optical ports of the OLMs are optimized for greater distances. The direct coupling of the optical ports of an OLM with an OBT or integrated optical ports is not possible due to differences in the technical specifications.

Ideally the module should be installed vertically. The modules can be inserted one beside the other without gaps being necessary. The module is attached to PROFIBUS-DP via a 9-pin sub-D female connector. The RS-232C interface is implemented as a 9-pin sub-D connector.
Topologies of SIMATIC NET PROFIBUS Networks Uses The PROFIBUS-DP/RS-232C link is a converter between an RS-232C (V.24) interface and PROFIBUS-DP. Devices with an RS-232C interface can be linked to PROFIBUS-DP with the DP/RS-232C link. The DP/RS-232C link supports the procedures 3964 R and free ASCII protocol.
Topologies of SIMATIC NET PROFIBUS Networks Parameter Assignment The PROFIBUS-DP address can be set using two switches on the front panel. To configure the unit, you use the GSD file and the configuration tool of the connected device, for example STEP 7. 2.5.6 Connecting with the DP/AS-Interface Link 65 Design Figure 2-20 DP/AS-Interface Link 65 The DP/AS-interface link has a robust aluminum die-cast casing with the degree of protection IP 65.

Topologies of SIMATIC NET PROFIBUS Networks Uses The DP/AS-interface link 20 implements a small, cost-effective link between PROFIBUS and AS-interface. The DP/AS-interface link 20 requires no additional power supply, the power is supplied on the AS-interface cable. The AS-interface segment can be started up without PROFIBUS-DP being in operation.
Topologies of SIMATIC NET PROFIBUS Networks How the DP/AS Interface Link 20 Works With the DP/AS-interface link 20, up to 248 binary elements are accessible to a DP master on the AS-interface (124 inputs and 124 outputs).

Configuring Networks 3.1 Configuring Electrical Networks PROFIBUS Networks PROFIBUS networks were specially designed for use in an industrial environment and one of their main features is their degree of immunity to electromagnetic interference resulting in high data integrity. To achieve this degree of immunity, certain guidelines must be adhered to when configuring electrical networks.
Configuring Networks Note The power supply to terminating resistors must not be interrupted by turning off the DTE or repeater or by unplugging the bus connector or tap line. If the power supply to the terminating resistors cannot be guaranteed, the PROFIBUS terminator must be used. 3.1.
Configuring Networks Length of the Tap Lines If you do not attach the LAN cable directly to the bus connector (for example,when using a PROFIBUS bus terminal), you must take into account the maximum possible tap line length! The following table shows the maximum permitted lengths of tap lines per bus segment: Table 3-2 Lengths of the Tap Lines per Segment Transmission rate 3.1.2 Max. length of the tap lines per segment Number of nodes with tap line length of ... 1.5 m or 1.6 m 3m 9.6 – 93.
Configuring Networks Value Factors To be able to define permitted configurations, a method is necessary with which the attached components can be evaluated in terms of their capacitive bus load. This is achieved by assigning value factors to the components (see Table 3-4 ). PROFIBUS interfaces implemented as 9-pin sub-D female connectors (CPs, OLMs...), do not have their own value factors. These are already taken into account in the values listed in the table. Table 3-4 Values for Segments at 1.
Configuring Networks Rules At a transmission rate of 1.5 Mbps, the following rules apply to the permitted number of nodes and their distribution/layout on a SIMATIC NET PROFIBUS segment: 1. The maximum permitted number of nodes on any segment is 32. 2. The sum of the values of all the connection elements in a segment must be ≤ 25. 3. The rules for the distance between adjacent connection elements are as follows (distance in this case is the length of the LAN cable): 3.
Configuring Networks Table 3-5 Examples Illustrating the Configuration Rules No special conditions if the length of the LAN cable between two DTEs > 10 m LAN cable > 10 m > 10 m S7-400 No special conditions if the length of the LAN cables between two DTEs is greater than the sum of values of both DTEs. If a bus terminal or a bus connector has a PG interface, a connected PG connecting cable must be taken into account when calculating the values. S7-300 Bus cable, e.g. 5 m V = 1.5 + 1.0 + 0.1 = 2.
Configuring Networks 3.1.
Configuring Networks 3.1.4 Configuring Electrical Networks with RS-485 Repeaters RS-485 Repeater To increase the number of nodes (>32) in a network or to extend the cable length between two nodes, segments can be connected together using RS-485 repeaters to form a network. Figure 3-1 illustrates how several segments can be connected together with repeaters to create a network. The RS-485 repeaters support all transmission rates from 9.6 Kbps to 12 Mbps.
Configuring Networks Configuring When configuring an electrical network with RS-485 repeaters, the following conditions must be taken into account: 3-10 S The maximum segment length for the transmission rate must be adhered to (see Table 3-1, Table 3-3, Table 3-6,) S The maximum number of bus attachments (nodes, OLMs, RS-485 repeaters,...) in one segment is restricted to 32. There may be further restrictions at a transmission rate of 1.5 Mbps (see Section 3.1.2).
Configuring Networks 3.2 Configuring Optical Networks Configuration Parameters for Optical Networks When configuring optical PROFIBUS networks, the following parameters must be taken into account: S Using fiber-optic cables, only point-to-point links can be established. S The maximum signal attenuation of the transmission path (the power budget) must be within the permitted values.
Configuring Networks 3.2.1 How a Fiber-Optic Cable Transmission System Works Introduction This section describes the structure and functions of an optical transmission system. The information here will help you to understand the rules for calculating the optical power budget in the next section. Transmission Path An optical transmission path consists of a transmitter, the optical fiber, and a receiver.
Configuring Networks Receiver The receiver of a digital optical transmission system consists of an optoelectric converter (a photodiode), that converts the optical signals to electrical signals and a signal converter that converts the electrical pulses received from the diode into signals compatible with the connected electronics.
Configuring Networks 3.2.2 Optical Power Budget of a Fiber-Optic Transmission System Optical Power Budget The transmitted optical power Pout and the received optical power Prec are specified in dBm, the attenuation caused by connectors and the fiber is specified in dB. dBm is a reference unit and describes the logarithmic ratio of the power level to the reference power P0=1mW.
Configuring Networks Power Budget The power budget of an optical link not only takes into account the attenuation in the fiber itself, temperature and aging effects but also the attenuation values of the connectors and splices and therefore provides exact information about whether or not an optical link can be implemented. The starting point for calculating the maximum transmission path length is the minimum transmitter power that can be coupled into the fiber type.
Configuring Networks Link Power Margin When calculating the power budget, a link power margin of at least 3 dB (at a wavelength of 860 nm) or at least 2 dB (at a wavelength of 1300 nm) must be maintained. If the link power margin calculated is lower, the transmission path will not be reliable in its currently planned form.
Configuring Networks 3.2.3 Cable Lengths for Plastic and PCF FO Paths The length of the transmission path on fiber-optic cables is not dependent on the transmission rate. Each node on the optical PROFIBUS network has repeater functionality so that the following distance information relates to the distance between two adjacent, interconnected PROFIBUS nodes. The maximum cable length between two PROFIBUS nodes depends on the type of fiber-optic cable used and the optical network components.
Configuring Networks Mixing Plastic Fiber-Optic and PCF Fiber-Optic To make the best use of the different cable lengths, the plastic fiber-optic cables and PCF fiber-optic cables can be mixed. For example, connection between distributed local DP slaves using plastic fiber-optic (distances t 50 m) and connection between DP master to the first DP slave of the bus topology with PCF fiber-optic (distance u 50 m). 3.2.

Configuring Networks 3.3.1 Configuring Optical Buses and Star Topologies with OLMs Creating a System Overview You configure the PROFIBUS network, for example with SIMATIC STEP 7. The bus-specific configuration begins with the creation of the system overview in the hardware configuration dialog “HW Config” of STEP 7 (V5.0). Figure 3-3 “HW Config” Dialog in STEP 7 (V5.
Configuring Networks Setting the PROFIBUS Properties In the “Properties – PROFIBUS” dialog, you can set the highest station address (HSA), the transmission rate and the bus profile.
Configuring Networks Entering the Cabling Configuration You can make the settings for the cabling configuration (number of OLMs, cable length) in the “Cables” tab under “Options”.
Configuring Networks Checking the Bus Parameters Based on the entries made, the configuration tool can check whether the slot time is feasible in the selected communication profile. If the system would exceed the value, due to the additional delays of OLM and FO cables, the parameters are adapted. The newly calculated bus parameters are displayed in the “Bus Parameters” dialog.
Configuring Networks 3.3.2 Configuring Redundant Optical Rings with OLMs The following configuration conditions must be satisfied in redundant optical rings: 1. Configuration of a Non-Existent Node 2. Raising the retry value to at least the value 3 3. Checking and adaptation of the slot time To set the parameters under point 2. and 3., use the user-specific profile of the configuration tool. There is an example of adopting the bus parameters in STEP 7 at the end of this section.
Configuring Networks Checking and Adapting the Slot Time To allow a “bumpless” return from the optical bus to the optical ring after the fault has been eliminated, there must be no frame on the network at the switch-back time. The network is briefly free of frames when a master addresses a device whose address is configured but does not actually exist. The master waits for a response until the configured slot time has elapsed.

Configuring Networks Note The slot time calculation takes into account only the optical network and the attachment of nodes to the OLM in each case via a maximum 20 m long RS-485 bus segment. Longer RS-485 bus segments must be included by adding them to the length FOC. With the OLM/G11-1300 and OLM/G12-1300, the minimum slot times shown in the following table must be maintained at transmission rates of 12 Mbps, 6 Mbps, 3 Mbps and 1.5 Mbps.

Configuring Networks Note Since the formula includes the delays of all fiber-optic and RS-485 cables, the “Consider Cable Configuration” check box must not be activated in the “Cables” tab on the “Options” dialog. Figure 3-7 3-32 “Bus Parameters/User-Defined” Dialog in STEP 7 (V5.

Passive Components for RS-485 Networks 4.6 Plugging the Bus Connector into the Module Fitting the Bus Connector To fit the bus connector, follow the steps outlined below: 1. Plug the bus connector into the module. 2. Screw the bus connector to the module. 3. If the bus connector is located at the start or end of a segment, you must activate the terminating resistor (switch setting ON”) (see Figure 4-26). It is not possible to activate the terminating resistor on the bus connector 6ES7 972-0BA30-0XA0.
Passive Components for RS-485 Networks ! Warning Possible disturbance of data traffic on the bus A bus segment must always be terminated at both ends with the terminating resistor. This is, for example, not the case when the power supply to the last node with a bus connector is turned off. Since the bus connector is supplied with power from the station, the terminating resistor has no effect. Make sure that the power supply for the stations on which a terminating resistor is activated is always turned on.
Passive Components for RS-485 Networks 4.7 Bus Terminals for RS-485 Networks 4.7.1 Versions Overview A bus terminal is used to attach a single PROFIBUS node with an RS-485 interface to the PROFIBUS LAN cable.

The pinout is identical to that shown in Table 4-10. Figure 4-28 RS-485 Bus Terminal with Additional PG Interface Note The SIMATIC NET PROFIBUS RS-485 bus terminals are only suitable for transmission rates ≤ 1.5 Mbps.
Passive Components for RS-485 Networks 4.7.
Passive Components for RS-485 Networks Bus terminal 12 M The 12M bus terminal is used to connect data terminal equipment (DTEs) with an RS-485 interface to the LAN cable. It includes the following: S 1 modular terminal block with 6 terminals for conductors with a cross-sectional area <= 1.
Passive Components for RS-485 Networks Termination The termination must be activated on the first and last node on the bus segment. If termination is activated (termination on), the connection between the incoming (A1, B1) and outgoing (A2, B20 segment is interrupted. The advantage of this is that if a bus terminating resistor is activated incorrectly, the stations after the bus terminal can no longer be accessed.
Passive Components for RS-485 Networks 4.7.4 Mounting/Attaching the LAN Cables The bus terminal can be mounted in three different ways: S By snapping it on to a 15 x 35 mm standard DIN rail (DIN EN50022-35x15) S By screwing the unit to a mounting plate using two fillister head screws. Figure 4-31 shows the drilling diagram for mounting the unit. Top edge of bus terminal 50 mm 42.5 mm Thread M4 or through-hole 4.2 mm 67.
Passive Components for RS-485 Networks Note Please make sure that the bus terminal is accessible for maintenance and installation work even during operation. To connect the LAN cable, follow the steps below (see Figure 4-32): 1. Open the LAN cable at the point at which the bus terminal will be inserted. 2. Strip approximately 33 mm of the outer sheath. Make sure when removing the sheath that the braid shield is not damaged. 3.
Passive Components for RS-485 Networks Note The shield clamps are used solely to contact the shields and are not suitable as strain-relief clamps. This means that the LAN cables must be secured as close as possible to the bus terminals to provide mechanical strain relief. Note Bus terminals installed at the end of segments require the 5 V power supply from the DTE interface to supply the activated, integrated terminating resistor.
Passive Components for RS-485 Networks 4.7.5 Grounding If the bus terminal is mounted on a DIN rail (see Figure 4-33), the shield clamp makes large-area contact with the rail via an internal spring. To connect the cable shield with local ground, a connection between the DIN rail over as short a distance as possible to local earth is adequate.
Passive Components for RS-485 Networks Note The DIN rail must have a good conducting surface (for example tin plated).

Passive Components for Electrical Networks 7.4 Fiber-Optic Connectors Note Fiber-optic connectors are impaired by dirt and mechanical damage to the end faces. Protect open connections with the supplied dust caps. 7.4.1 Connectors for Plastic Fiber-Optic Cables Fitting connectors to plastic fiber-optic cables is relatively simple. The following connectors are available: 7.4.
Passive Components for Electrical Networks Design For a fiber-optic attachment, two simplex connectors (transmitter and receiver) and, if necessary, also an adapter with the following characteristics are required: S Degree of protection IP 20 S Transmission rates from 9.
Passive Components for Electrical Networks Cable Lengths The length of the transmission path on fiber-optic cables is not dependent on the transmission rate. Each node on the optical PROFIBUS network has repeater functionality so that the following distance information relates to the distance between two adjacent, interconnected PROFIBUS nodes in a bus topology. The maximum cable length between two PROFIBUS nodes depends on the type of fiber-optic cable used.
Passive Components for Electrical Networks Mixing Plastic Fiber-Optic and PCF Fiber-Optic To make the best use of the different cable lengths, the plastic fiber-optic cables and PCF fiber-optic cables can be mixed. For example, connection between distributed local DP slaves using plastic fiber-optic (distances t 50 m) and connection between DP master to the first DP slave of the bus topology with PCF fiber-optic (distance u 50 m).
Passive Components for Electrical Networks 7.4.3 BFOC Connectors for OLMs The BFOC connectors allow precision fiber-optic cable connections. The construction of the BFOC connector allows the strain relief of cables to be used. This is necessary for installing longer fiber-optic cable connections, for example between OLM/P modules. BFOC connectors must be ordered separately. Ordering information and instructions on fitting the connectors can be found in Appendix D.
Passive Components for Electrical Networks Fitting Connectors On-Site If it is necessary to fit connectors on-site, – SIEMENS provides this service (see Appendix I-2) – BFOC connectors and special tools can be ordered (see I-2). Note Connectors for glass fiber-optic cables should only be fitted by trained staff. When fitted correctly, they allow extremely low coupling attenuation and the value can be repeated after inserting the connector several times.

The following errors can be detected: S Short-circuit between data lines or between data line and shield S Line break S Shield break S Reversed polarity (A and B) S Reflections that could cause errors S Check of the number of activated terminating resistors The length of the PROFIBUS cable can also be measured.
Testing PROFIBUS A.1.6 How the Unit Functions Testing Cables The previously described tests and measurements are based essentially on various voltage, reflection and resistance measurements. To check the cable, the test unit is connected to one end of the cable and a test connector at the other. When installing the cable, the user works gradually from connector to connector. At the press of a button the measurements are made automatically and the test results displayed.

Testing PROFIBUS A.2 Testing FO Transmission Paths A.2.1 Necessity of a Final Test The total attenuation of an FO transmission path, particularly the influence of splices, can only be estimated roughly during planning. As a result of inaccuracies when creating the splices and subjecting cables to excessive stress during installation, the actual attenuation may well be higher than the calculated values.
Testing PROFIBUS Arrangement for Measuring Attenuation The arrangement for measuring attenuation consists of a light source and an optical meter. The light source is first connected to the receiver via a reference fiber. The optical power measured at the receiver is the reference value for a link without attenuation. Following this, the reference fiber is opened and the link to be measured is inserted.
Testing PROFIBUS A.2.3 Optical Time Domain Reflectometer (OTDR) If the attenuation measurement described above indicates that the total attenuation of the fiber-optic link is too high, the causes and the location of the problem must be established. In this case OTDR units are used (OTDR = Optical Time Domain Reflectometer). Figure A-3 Optical Time Domain Reflectometer (OTDR) OTDRs exist for the wavelengths 850 nm and 1300 nm.
Testing PROFIBUS How an OTDR Functions An OTDR can be compared to a radar unit The OTDR sends laser light pulses on the FO cable to be tested (the end of the cable is open). These light pulses are reflected more or less strongly by all problem points along the cable. A meter evaluates the intensity and propagation time of the reflected pulses.

There are significant jumps at the coupling points of the fiber.
Testing PROFIBUS A.2.4 Checking the Optical Signal Quality with PROFIBUS OLM V3 The receive level of the two optical channels can be detected using a normal commercially available voltmeter attached to measurement sockets on the PROFIBUS OLM V3. The voltmeter can be inserted and removed during operation using 2 mm laboratory test plugs (see Figure A-6).

Lightning and Surge Voltage Protection for LAN Cables Between Buildings B.1 Why Protect Your Automation System From Overvoltage? Introduction One of the most common causes of hardware failures is overvoltage, caused by the following: S Switching in power networks S Atmospheric discharge or S Electrostatic discharge We will show you how to protect devices attached to a PROFIBUS LAN cable from overvoltages.
Lightning and Surge Voltage Protection for LAN Cables Between Buildings LAN Cables between Buildings Since LAN cables between buildings are subject to higher overvoltage risks (the effects of lightning), the nodes included in the attached bus segment must be protected from the effects of overvoltage. Lightning protection facilities for LAN cables are implemented in two different components, coarse protection and fine protection.

Lightning and Surge Voltage Protection for LAN Cables Between Buildings B.2.1 Instructions for Installing Coarse Protection The coarse protection must be installed at the point where the LAN cable enters the building and connected to the building equipotential bonding system with low impedance. The following are required to create the coarse protection: S The base section type no. 919506, S The protection module type B, type no. 919510 and S The shield contact terminals type no.
Lightning and Surge Voltage Protection for LAN Cables Between Buildings B.2.2 Instructions for Installing Fine Protection The fine protection should be installed as close as possible to the first bus node following the coarse protection. The following are required to install the fine protection: S The base section type no. 919506, S The protection module MD/HF type no. 919570, and S The shield contact terminals type no.
Lightning and Surge Voltage Protection for LAN Cables Between Buildings B.2.3 General Information on the Lightning Protection Equipment from the Firm of Dehn & Söhne S When installing the modules read the instructions regarding the products from Dehn & Söhne. S If there is a fault in a lightning protection module, communication on the bus is interrupted (cable short-circuit).

Installing LAN Cables C.1 LAN Cables in Automation Systems LAN Cables as Important Plant Connections In automation systems, the LAN cables are the most important connections between individual plant components. Mechanical damage (cable break) or repeated electrical interference affecting these bus connections reduces the transmission capacity of the system. In extreme cases, such problems can lead to failure of the entire automation system.
Installing LAN Cables C.2 Electrical Safety The signal levels on electric PROFIBUS cables are low voltage. Correctly installed and operated PROFIBUS LAN cables do not have dangerous electrical voltages. Remember, however, the following rules when installing the power supply for all components (nodes, bus components, etc.) that you want to connect to a PROFIBUS cable.
Installing LAN Cables C.3 Mechanical Protection of LAN Cables Protection of Electrical and Optical LAN Cables Mechanical protection is required to protect LAN cables from breaks or mechanical damage. Note The guidelines for mechanical protection apply both to electrical and optical cables.
Installing LAN Cables Figure C-2 Interrupting the Conduit at an Expansion Joint Bus Terminal RS-485 The installation of electrical LAN cables in a protected area is supported by the use of the RS-485 bus terminal. This allows the attachment of DTEs and service and commissioning work on the DTEs without needing to move the actual LAN cable. Redundant LAN Cables The installation of redundant LAN cables involves special requirements.
Installing LAN Cables Install LAN cables separately To prevent accidental damage to LAN cables, they should be clearly visible and should be separate from all other wiring and cables. To improve EMC, it is often advisable to install the LAN cables in a separate cable channel or in conductive, metal tubes. Such measures also make it easier to localize a faulty cable.
Installing LAN Cables C.4 Electromagnetic Compatibility of LAN Cables Electromagnetic Compatibility (EMC) Electromagnetic compatibility (EMC) includes all questions of electrical, magnetic and electromagnetic immunity and emission. To avoid external interference affecting electrical systems, these effects must be reduced to a certain level. The measures involved include the design, structure and correct connection of the LAN cable.
Installing LAN Cables C.4.2 Installation and Grounding of Inactive Metal Parts Grounding Connect all inactive metal parts in the immediate vicinity of your automation components and LAN cables to ground (PE system). This includes all metal parts of cabinets, machine parts etc. that have no electrical function in the automation system. Connecting these parts to a uniform system chassis produces a uniform reference potential for your system and reduces the effects of coupled-in interference.
Installing LAN Cables Note If there is a potential difference between the grounding points, an illegally high compensating current can flow through the shield grounded at both ends. To rectify the problem, do not, under any circumstances, open the shield of the LAN cable. S Install an additional bonding conductor parallel to the LAN cable that takes over the shield current (for notes on equipotential bonding refer to Section C.4.4) S Use fiber-optic cable instead of electrical cable (safest solution).
Installing LAN Cables S When removing the sheath of the cable, make sure that the braid shield of the cables is not damaged. S When selecting contact elements, remember that the cables for SIMATIC NET PROFIBUS have a braid shield outer diameter of approximately 6 mm. S To allow good contact between grounding elements, tin-plated or galvanically stabilized surfaces are ideal. With galvanized surfaces, the necessary contact should be achieved using suitable screws.
Installing LAN Cables How do you avoid potential differences? Potential differences must be reduced by installing bonding conductors so that the functions of the electronic components used are guaranteed. When and why is equipotential bonding necessary? The following reasons speak in favor of equipotential bonding: S Devices with a grounded interface can be damaged by potential differences. S The shield of the PROFIBUS cable must not be used for equipotential bonding.
Installing LAN Cables Note Bonding conductors are unnecessary if the sections of a system are connected exclusively using fiber-optic cable (FO).
Installing LAN Cables C.5 Routing Electrical LAN Cables Voltages and Currents Wiring and cables in a system conduct voltages and currents. Depending on the application, the amplitudes can be of an order much higher than the signal voltage on the cable. Switching supply voltages can, for example, produce sharply rising surge voltage peaks in the kV range. If other cables are laid parallel to the LAN cable, data exchange on the LAN cables can be disturbed by crosstalk.
Installing LAN Cables Conditions Grouping cables according to voltage classes assumes that the interference voltages relate directly to the power supply voltage conducted (the lower the supply voltage, the lower the interference voltage). Remember, however, that DC or 50 Hz power supply voltages do not represent any danger to PROFIBUS cables. The critical interference voltages in the kHz to MHz frequency range are created by the “consumer” connected to the cable.

In common bundles or cable channels Data signal, shielded (PG, OP, printer, counter inputs etc.
Installing LAN Cables C.5.2 Cabling within Closets When cabling within wiring closets, note the following points: C.5.3 S The minimum clearance between cables of different categories can be found in Table C-1. In general, the risk of interference due to crosstalk is less the greater the clearance between the cables. S Where cables of different categories cross, they should cross at right angles (keep sections where the cables run parallel as short as possible).
Installing LAN Cables C.5.4 Cabling outside Buildings Fiber-optic cables should be given preference For communications between buildings and between buildings and external facilities, the use of fiber-optic cables is generally recommended. Due to the optical transmission principle, fiber-optic cables are not affected by electromagnetic interference. Measures for equipotential bonding for overvoltage protection are unnecessary with fiber-optic cables.
Installing LAN Cables Underground Cabling Note Only the SIMATIC NET PROFIBUS underground cable is suitable for direct installation underground. If the LAN cables are installed directly in the earth, we recommend the following: C.5.5 S install the LAN cable in a trench. S Install the LAN cable approximately 60 cm below the surface of the ground. S Mechanical protection should be provided for the LAN cables and a cable warning band should also be included.
Installing LAN Cables Cabinet Lighting Use bulbs for the cabinet lighting, for example LINESTRAR lamps. Avoid the use of fluorescent lamps since they cause interference. If you need to use fluorescent lamps, take the measures shown in Figure C-5.
Installing LAN Cables C.6 Electromagnetic Compatibility of Fiber-Optic Cables Fiber-Optic Cables For LAN cables between buildings and/or external facilities, the use of fiber-optic cables is generally recommended. Due to the optical transmission principle, fiber-optic cables are not affected by electromagnetic interference. Measures for equipotential bonding and for overvoltage protection are unnecessary with fiber-optic cables.
Installing LAN Cables C.7 Installing LAN Cables C.7.1 Instructions for Installing Electrical and Optical LAN cables General During installation, remember that LAN cables can only be subjected to a certain amount of mechanical strain. Cables can be damaged or even destroyed by too much tensile stress or pressure, by torsion or by bending them too sharply. The following instructions will help you to avoid damage when installing LAN cables.
Installing LAN Cables Fitting Strain Relief Make sure that you provide strain relief approximately 1 m from the connection point on all cables subject to tensile force. Shield clamps are not adequate for strain relief. Pressure Too much pressure on the cables must also be avoided, for example crimping the cable when securing it in position. Torsion Torsion can lead to the elements of a cable being displaced and degrading the electrical characteristics of cables. LAN cables must not be twisted.
Installing LAN Cables Avoid Loops When laying LAN cables, roll them tangentially from the cable drum or use appropriate rotary tables. This prevents loops forming and resulting in kinks and torsion. Installing other Cables Remember that LAN cables must not be subjected to excessive strain and stress when installed.
Installing LAN Cables C.8 Additional Instructions on Installing Fiber-Optic Cables Protecting Connectors from Contamination Fiber-optic cable connectors are sensitive to contamination. Unconnected male and female connectors must be protected with the supplied dust caps. Attenuation Variations under Load During installation, the fiber-optic cables must not be twisted, stretched or crimped. The specified limit values for tensile strain, bending radii and temperature ranges must be adhered to.
Installing LAN Cables Attaching PROFIBUS Fiber–Optic Cables The attachment of the various PROFIBUS fiber–optic cables to optical bus components (OLM, OBT,...) and devices with an integrated optical interface is described in the chapter ”Passive Components for Optical Networks” and in Appendix D.

6ZB5530–3AC30–0BA1 3 Infrared Link Modul (ILM) Introduction The SIMATIC NET PROFIBUS ILM (Infrared Link Module) is intended for use in PROFIBUS networks. It allows the conversion of electrical PROFIBUS interfaces (RS 485 level) into transmittable light signals in the infrared, invisible wavelength range and vice-versa.
Infrared Link Modul (ILM) 4 6ZB530–3AC30–0BA1 Description of the Device Each PROFIBUS ILM has an optical and an electrical channel each with a transmitter and receiver section. The sending PROFIBUS node generates an electrical signal with RS 485 level that is transferred via the PROFIBUS cable to the PROFIBUS ILM of the sending PROFIBUS node. The PROFIBUS ILM converts this electrical signal to a coded light signal.
6ZB5530–3AC30–0BA1 Infrared Link Modul (ILM) SIEMENS Figure 1: PROFIBUS ILM PROFIBUS ILM The mechanical construction is a compact, stable metal housing (splash-water protected) with degree of protection IP65. The casing must be mounted by the user on a grounded surface with two screws. When shipped, the data rate is set to 1.5 Mbps, the signaling contact is not activated if errors occur and the terminating resistor is not activated.
Infrared Link Modul (ILM) 6ZB530–3AC30–0BA1 5 Description of the Functions 5.1 Transmission Rate The SIMATIC NET PROFIBUS ILM supports the following transmission rates: 9.6 Kbps 19.2 Kbps 45.45 Kbps 93.75 Kbps 187.5 Kbps 500 Kbps 1.5 Mbps (default) The transmission rates of the connected network nodes can have the tolerance of )/–0.3% as specified in the PROFIBUS standard. 5.

Infrared Link Modul (ILM) + 6ZB530–3AC30–0BA1 Make sure that the infrared link cannot be disturbed, for example by “interrupting” the link with obstacles, extraneous light etc. When cascading with PROFIBUS ILM, only one segment with master nodes is permitted, the cascaded segments must only contain slave nodes.

Infrared Link Modul (ILM) 5.2.2 6ZB530–3AC30–0BA1 Point–to–Multipoint Link Instead of the multiple use of point-to-point links, the point-to-multipoint link can also be used. Optical isolation between the infrared transmission links is not necessary. If the configuration is correct, only one slave node responds to the request of a master node and because there is only one PROFIBUS ILM on the master network segment, there are no synchronization problems with the response.

Infrared Link Modul (ILM) 5.3 6ZB530–3AC30–0BA1 Signal Regeneration The PROFIBUS ILM regenerates the signal shape and amplitude of the received signals. This makes it possible to cascade unconnected network segments using infrared transmission links. Since the PROFIBUS ILM, however, has a delay time for processing and passing on the signal the delay on the PROFIBUS ILM must be taken into account.
6ZB5530–3AC30–0BA1 5.6 Infrared Link Modul (ILM) Monitoring the Optical Link The PROFIBUS ILM has two mechanisms with which it monitors problems on the optical link. – monitoring of the optical receive activity – monitoring of the optical link with an acknowledgment pulse 5.6.1 Monitoring the Optical Receive Activity With the yellow “RX” LED, the PROFIBUS ILM indicates the reception of data via the optical channel of the PROFIBUS ILM.
Infrared Link Modul (ILM) 6ZB530–3AC30–0BA1 This monitoring logic must not be used on a point-to-multipoint link. Otherwise problems can occur in the PROFIBUS network. The display of the acknowledgment pulse function is one of the functions of the “TX” LED. With the yellow “TX” LED, the PROFIBUS ILM indicates that data are being sent on the optical channel of the PROFIBUS ILM. The pulse for the LED is extended to approximately 300 ms so that send activity can also be recognized with short data fields.
6ZB5530–3AC30–0BA1 6 Infrared Link Modul (ILM) Modes and Settings To operate the PROFIBUS ILM, the terminating resistor, the data rate and the monitoring options must be set manually. Note: When shipped, the configuration is as follows: â The terminating resistor is inactive â The data rate is set to 1.5 Mbps â The “monitor link with acknowledgment pulse” monitoring mechanism is inactive. â The activation of the signaling contact is disabled.
Infrared Link Modul (ILM) 6.1 6ZB530–3AC30–0BA1 Setting the Terminating Resistor Electrical cables in a PROFIBUS network must be terminated with the characteristic impedance of the cable at the start and end of the bus. Switch S202 is used for this purpose on the basic module of the PROFIBUS ILM. Note Note that the switch must be set to “terminating resistor activated” if a PROFIBUS ILM is located at the start or end of an electrical PROFIBUS network (only one PROFIBUS cable connected).
6ZB5530–3AC30–0BA1 6.2 Infrared Link Modul (ILM) Setting the Transmission Rate To operate the PROFIBUS ILM, the transmission rate must be set manually. The transmission rates normal in PROFIBUS (9,6 Kbps to 1.5 Mbps) are possible and in addition also the transmission rate of 45.45 Kbps. The transmission rate of the attached bus nodes must be within the tolerance of )/– 0.3%. The user must set the same transmission rate on all PROFIBUS ILMs in a PROFIBUS network.
Infrared Link Modul (ILM) 6.3 6ZB530–3AC30–0BA1 Operation With Acknowledgment Pulse For operation of the PROFIBUS ILM with acknowledgment pulses, a manual setting must made during configuration. Operation with acknowledgment pulse is only intended for the use of point-to-point links between two PROFIBUS ILMs. Note If a point-to-multipoint topology is being used, this mechanism must be deactivated otherwise problems can occur on the bus.
6ZB5530–3AC30–0BA1 6.4 Infrared Link Modul (ILM) Operation with Signaling Contact The signaling contact is used to monitor the PROFIBUS ILM via a digital input on a PLC or as part of a current loop. If problems occur the contact opens, in other words a connected current loop is then interrupted. By setting four switches, the user decides which events trigger the signaling contact.

6ZB5530–3AC30–0BA1 Infrared Link Modul (ILM) 7 Installation and Startup 7.1 Notes on Safety â Use the PROFIBUS ILM only as described in this “description and operating instructions”. â Never connect the PROFIBUS ILM to the mains power supply 110 V – 240 V. â In particular, take note of all the warnings and notes relating to safety. â The operating voltage must be a safety extra-low voltage complying with IEC 950/EN 60 950/VDE 0805 of maximum +30V (typically )24 V).
Infrared Link Modul (ILM) 7.2 6ZB530–3AC30–0BA1 General Notes on Installation and Startup First, select the network topology suitable for your system. You can then install and start up the PROFIBUS ILM step-by-step as shown below: 3 Check the area for suitable sites where you can install the modules. 3 Make mounting brackets suitable for the sites you have chosen. Chapter 8 describes an example of a general-purpose support consisting of two identical mounting brackets that are easy to make.
6ZB5530–3AC30–0BA1 Infrared Link Modul (ILM) transmission errors. The red “LOW” LED should only be lit when the level on the infrared link is close to the minimum receive level (operation at the edge of the illumination cone). 3 Check the data exchange for incorrect data using SCOPE for PROFIBUS (TMG i-tec), a tool for diagnostics on PROFIBUS networks.
Infrared Link Modul (ILM) 8 6ZB530–3AC30–0BA1 Installing the PROFIBUS ILM The PROFIBUS ILM can be mounted with two screws on a flat surface (approximately 180 x 80 mm). This can be a wall, a mounting plate or the surface of a device or vehicle. The holes in the PROFIBUS ILM are intended for screws with a thread diameter of maximum 4.5 mm and a screw head diameter of maximum 8.5 mm. Figure 11 shows the location of the holes drilled in the ILM.
6ZB5530–3AC30–0BA1 Infrared Link Modul (ILM) Make sure that there are no infrared sources in the illumination cone in front of a PROFIBUS ILM. There should also be no reflecting surfaces in any part of the illumination cone to avoid reflecting back the modules own emission. Before mounting the PROFIBUS ILM, connect the power supply and PROFIBUS cables if the site where the module is being installed is awkward to reach.

Infrared Link Modul (ILM) 8.1 6ZB530–3AC30–0BA1 Connecting the Electrical RS 485 Bus Cables For the RS 485 bus cable, use only shielded twisted pair cables with an outer diameter of 7.5 to 10 mm. Appendix B lists the electrical parameters of cable types recommended in compliance with the standard. Make sure that you connect the same cores (green or red) uniformly to all bus terminals of a cable section, either terminal A or terminal B.
6ZB5530–3AC30–0BA1 Infrared Link Modul (ILM) If the device is at the start or end of an electrical PROFIBUS segment, you must seal one threaded cable inlet using the accompanying sealing plug. If the mechanical stress on the PROFIBUS cable is liable to change, make sure that you install additional strain relief. The cable clamp in the device itself is only intended for low-resistance discharge of spurious voltages on the shield.
Infrared Link Modul (ILM) 8.2 6ZB530–3AC30–0BA1 Connecting the Power Supply and the Signaling Contact Use a two-wire round cable if you do not want to use the signaling contact or a four-wire round cable if the signaling contact is required. This is necessary so that the threaded cable inlet seals the cable entry and prevents the cable from being pulled out. Ideally, you should use twisted pair cables since they are less susceptible to noise. The outer diameter of the cables must be between 7.

6ZB5530–3AC30–0BA1 Infrared Link Modul (ILM) If no display indicates an error and communications problems nevertheless occur, check the parameters set on both PROFIBUS nodes. You should also check the electrical RS 485 wiring. The most common cause of problems is activating or deactivating the terminating resistor incorrectly. You should also check that the cable shields at the ends of all PROFIBUS cables and all shielded power supply cables are making satisfactory contact.
Infrared Link Modul (ILM) 10.2 6ZB530–3AC30–0BA1 Errors Due to Incorrect Network Configuration In large PROFIBUS networks with numerous modules and long cable lengths, the delay caused by network components and cables (transmission delay) must be taken into account when setting the monitoring times. If you do not take these delay times into account, problems will occur during operation.
6ZB5530–3AC30–0BA1 Infrared Link Modul (ILM) Converted to bit times this results in the following: Transmission Rate in Kbps Table 2: Delay Time in bit times per km 9.6 0.05 19.2 0.10 45.45 0.23 93.75 0.47 187.5 500.0 0.94 2.50 1500.0 7.50 Delay Times of Fiber-Optic and RS 485 LAN Cables To calculate the cable delay time, the maximum cable length in km is multiplied by the delay time corresponding to the transmission rate from the table. 10.2.

6ZB5530–3AC30–0BA1 11.1 Infrared Link Modul (ILM) Illumination Range To determine the arrangement of two PROFIBUS ILMs on an infrared transmission link, the illumination range of the sending PROFIBUS ILM must be known. The receive cone is broader so that with the half-duplex transmission used with PROFIBUS the restriction results from the narrower cone. Note Each PROFIBUS ILM on an infrared link must be arranged and aligned so that it reaches its partner with its transmit cone.

1 Introduction 1 Introduction The PROFIBUS OLM (Optical Link Module) product family consists of OLM/P11, OLM/P12, OLM/G11, OLM/G12, OLM/G12-EEC, OLM/G11-1300 and OLM/G12-1300. PROFIBUS OLMs are designed to be used in optical PROFIBUS field bus networks. They enable electrical PROFIBUS interfaces (RS 485 level) to be converted into optical PROFIBUS interfaces and vice-versa.
1 Introduction Table 1 shows the different methods for connecting the modules, and the maximum optical ranges of each port. OLM/ Number of ports – electrical – optical Fiber types – Plastic optical fibers 980/1000 µm – PCF optical fibers 200/230 µm Quartz glass optical fibers 10/125 µm 50/125 µm 62.
2 General Functions 2.1 Non operating mode related functions 2 General Functions 2.1 Non operating mode related functions Transmission rate The PROFIBUS OLMs support all the transmission speeds (transmission rates) defined in the EN 50170 standard: 9.6 kBit/s, 19.2 kBit/s, 45.45 kBit/s, 93.75 kBit/s, 187.5 kBit/s and 500 kBit/s, and additionally 1.5 MBit/s, 3 MBit/s, 6 MBit/s and 12 MBit/s. The transmission rate is set automatically as soon as the PROFIBUS OLM receives a frame.
2 General Functions 2.2 Operating mode related functions The following functions are only available for the optical ports. Whether the functions can be activated depends on the operating mode which has been set. Please refer to the following chapters for details. Line monitoring with echoes The modules enable the connected optical paths to be actively monitored for interruptions in the fiber line by means of the functions ”Send echo“, ”Monitor echo“ and ”Suppress echo“.
3 Network Topologies 3.1 Line topology 3 Network Topologies The following network topologies can be realized with the PROFIBUS OLM: Point-to-point connections Line topologies Star topologies Redundant optical rings Combinations of these basic types are also possible. Lines with two optical fibers are used to create the fiber links for these network topologies. If a malfunction – e.g.
3 Network Topologies 3.1 Line topology In a line structure, the individual PROFIBUS OLMs are connected together by dual-fiber optical fibers. Modules with one optical port are sufficient at the beginning and end of a line, between which modules with two optical ports are necessary. If single point-to-point connections are to be built up, this can be achieved using two modules each with one optical port. The line topology can be realized with and without fiber link monitoring.
3 Network Topologies 3.1 Line topology 3.1.2 Line topology without optical fiber link monitoring Use this operating mode if you connect a PROFIBUS OLM with another optical fiber network component, which does not send a frame echo and does not expect or is not compatible with a frame echo in accordance with PROFIBUS guidelines (optical/electrical converter).
3 Network Topologies 3.2 Star topology 3.
3 Network Topologies 3.2 Star topology Switch on the terminating resistors in the bus port connectors (see 4.4.3, ”Connecting the electric RS 485 bus lines“, p. 22) at both ends of the electrical star segment. Do not connect a bus subscriber to the electrical star segment wherever possible. Modules with one or two optical ports can be used to create an active PROFIBUS star coupler.
3 Network Topologies 3.3 Redundant optical ring This network topology represents a special form of line topology. A high degree of network operating safety is achieved by ”closing“ the optical line. A redundant optical ring can only be realized with modules with two optical ports of the same type.

1 Introduction The PROFIBUS OBT (Optical Bus Terminal) is a network component for use in optical PROFIBUS DP fieldbus networks. It allows the attachment of a single device without an integrated optical interface to the optical PROFIBUS DP. The following figure illustrates a typical configuration.
Introduction Connections The connection between the individual nodes takes the form of an optical bus with two-fiber plastic FO cables (plastic fiber-optic cables are also known as POF, Polymer Optical Fiber) or PCF FO cables (PCF = Polymer Cladded Fiber, corresponds to HCSt 1) fiber-optic cable). Since fiber-optic cables are completely insensitive to electromagnetic disturbance, no grounding concept whatsoever is necessary. For the same reason, equipotential bonding is also not necessary.

Functional Description 3 The OBT is a repeater with 3 channels. 3.1 Interfaces The OBT has the following interfaces for attachment to PROFIBUS DP segments: S Channel 1 (CH1) is an electrical RS-485 interface. This is implemented as a 9-pin D SUB female connector. A single PROFIBUS DP node can be connected via this channel or a PC, PG or OP can be connected to the OBT. The maximum permitted segment length is 100 m.
Functional Description 3.3 Automatic Transmission Rate Detection The OBT supports all PROFIBUS transmission rates (12 Mbps , 6 Mbps, 3 Mbps, 1.5 Mbps, 500 Kbps and 187.5 Kbps, 93.75 Kbps, 45.45 Kbps, 19.2 Kbps, 9.6 Kbps). The transmission rate is detected automatically. No settings are necessary. 3.
Functional Description L+ 24V (green) Unlit: No power supply or internal power supply is defective or short-circuited Flashes: Power supply present; Transmission rate not yet set Lit green: Transmission rate set, power supply O.K.
Functional Description 3.6 Operator Controls The OBT itself does not have operator controls. Care must simply be taken that the PROFIBUS connecting cable (not supplied) attached to Channel 1 is terminated at both ends.
Network Topology 4.1 4 Optical Bus The OBT is operated in conjunction with other SIMATIC devices, for example the IM 153-2 FO or IM 467 FO on the optical PROFIBUS DP in the form of an optical bus. Individual PROFIBUS DP nodes with an RS-485 interface are connected to channel 1 of the OBT via a maximum 100 m long PROFIBUS cable with bus connectors fitted at both ends. The terminating resistors on the bus connectors must be activated. An active or passive PROFIBUS DP node can be connected.
Network Topology 4.2 Using Long Fiber Optic Sections The maximum permitted length of PCF FO cables with the OBT is 300 m. If longer distances are required with fiber-optic cables, then other fiber-optic types such as graded glass fibers or monomode fibers are necessary and these can be used in a combination of OBT with OLM (Optical Link Module). The OBT is then connected electrically to the OLM (for example OBT/CH 1 to OLM/CH 1) and the OLM is attached to the long fiber-optic section.
Network Topology 4.3 Attaching RS-485 Segments The OBT allows the attachment of a single PROFIBUS DP node. To attach RS-485 segments with more than one node, a further network component is available, the OLM 12M. The requirement for using the OLM 12M is that the PROFIBUS DP network is operated at a transmission rate of 187.5 Kbps, 500 Kbps, 1.5 Mbps or 12 Mbps.

Installation and Startup 5 Note Use the PROFIBUS OBT only as described in this manual. Note Pay particular attention to all warnings and safety–related instructions. Note The PROFIBUS OBT must only be operated with a safety extra-low voltage (SELV) complying with IEC 950/ EN 60 950/ VDE 0805 with a maximum of +32 V (typically +24 V). The power source must comply with the regulations of NEC class 2 according to the UL/CSA approval.
Installation and Startup Note The RS-485 channel CH1 of the PROFIBUS OBT is electrically isolated from the 24V input. This isolation is required for correct functioning and is not a safety measure. Note Make sure that the PROFIBUS OBT is adequately grounded by connecting the rail or mounting plate to local ground with low resistance and low inductance. Note As the RS-485 cable, use only LAN cables approved for PROFIBUS. Note Do not open the OBT casing. 5.
Installation and Startup 5.2 Installation Installing the PROFIBUS OBT PROFIBUS OBT can be installed either on a 35 mm standard rail with a height of 15 mm in compliance with DIN EN 50 022 – 35 x 15 or directly on a level surface. S Select the installation location so that the climatic limit values listed in the technical specifications can be adhered to. S Make sure there is enough space for connecting the bus and power supply cables.
Installation and Startup Installation on a Mounting Plate PROFIBUS OBTs have two holes drilled in them. This allows them to be installed on any flat surface, for example on the mounting plate of a cubicle. S Drill two holes in the mounting plate as shown in the drill template in Figure 5-2. S Secure the modules with machine screws (for example M3 x 75 and M3 x 55). S Use a grounding conductor with at least 2.

S Make sure that in each case an optical input is connected to an optical output (crossover).
Installation and Startup Note If the fiber protrudes beyond the surface of the connector, the connector must not be inserted into the socket otherwise the optical components can be permanently damaged. Connecting the Electrical RS–485 Cable Channel CH1 is used to connect a single PROFIBUS DP DTE. CH1 is designed as an electrical RS 485 interface with a 9-pin sub D female connector. The maximum cable length between the OBT and DTE is 100 m.
