General Information 1.2 Local Area Networks in Manufacturing and Process Automation General 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 operator control and monitoring, this also means a high-performance communication system.
General Information What Does SIMATIC NET Stand For? With SIMATIC NET, SIEMENS provides open, heterogeneous communication systems for the various levels of process automation in an industrial environment.

Industrial Ethernet Networks Communication in an Industrial Environment The requirements of communication in an industrial environment differ significantly from those of conventional office communication. This affects practically all aspects of communication, such as active and passive network components, attached DTEs, network concepts/topologies, availability, data traffic, and environmental conditions, to name but a few.
Industrial Ethernet Networks 2.1 Ethernet Standard IEEE 802.3 IEEE Standard 802.3 The international “Institute of Electrical and Electronic Engineers (IEEE)” specified the first Ethernet standard 10BASE5 /1/ in 1985. This standard based on coaxial cable as the transmission medium was the basis for the first Industrial Ethernet. Under the name SINEC H1, this network, enhanced by the introduction of a triaxial cable, has proved itself for many years in process and manufacturing automation /6/.
Industrial Ethernet Networks Network Access Using the CSMA/CD Protocol CSMA/CD (Carrier Sense Multiple Access with Collision Detect) is also known as Listen While Talk (LWT). This is a distributed access technique; in other words, each DTE connected to the network has the same access rights. If a DTE wants to send data, it first “listens” to the medium to find out whether another DTE is already transmitting. If no other DTE is transmitting, it can start its transmission.
Industrial Ethernet Networks 2.2 Industrial Ethernet Industrial Twisted Pair (10BASE-T) Industrial Twisted Pair is based on the Twisted-Pair standard IEEE 802.3i (10BASE-T) /3/ and operates at a transmission rate of 10 Mbps. The transmission medium is a shielded cable with two twisted pairs with a characteristic impedance of 100 ohms. It is terminated according to the 10BASE-T standard with RJ-45 connectors. As an alternative, sub-D connectors are also available in the SIMATIC NET product range.
Industrial Ethernet Networks 2.3 Fast Ethernet Fast Ethernet /5/ has the essential features of the classic Ethernet standard with a data rate increased by a factor of 10 to 100 Mbps. The data format, the CSMA/CD protocol and the glass fiber-optic cables and category 5 twisted-pair cables are identical in both systems.
Industrial Ethernet Networks Industrial Twisted Pair (100BASE-TX) Fast Ethernet over twisted pair is based on the standard IEEE 802.3u (100BASE-TX) /5/ and operates at a transmission rate of 100 Mbps. The transmission medium is a shielded cable with two twisted pairs with a characteristic impedance of 100 ohms. The transmission properties of this cable must meet the requirements of category 5 cabling (see Glossary).
Industrial Ethernet Networks 2.4 Switching Basic Principles of Switching Switches forward data packets directly from the input port to the output port based on the address information in the data packet. Switches allow, as it were, a direct interconnection. A switch has essentially the following functions: S Connecting Collision Domains / Subnets Since repeaters and hubs (star couplers) function at the physical layer, their use is restricted to the span of a collision domain.
Industrial Ethernet Networks S Parallel Communication Switches have the capability of handling multiple data packets between different network segments or nodes simultaneously. Depending on the number of ports the switch has, it establishes several temporary and dynamic links between different pairs of network segments/terminals. The result is an enormous increase in the network’s data throughput, and a considerable increase in network efficiency.
Industrial Ethernet Networks 2.5 Example of an Industrial Ethernet Network Figure 2-2 shows an example of the combination of different technologies and generations of Industrial Ethernet products in one network. Network 1 In the high-speed network 1, four OSMs form a redundant ring with 100 Mbps transmission capacity. If the connected DTEs or network components are suitably designed, the twisted-pair ports of the OSMs can also be operated at 100 Mbps.

Configuring Networks 3.1 Shared LANs (CSMA/CD Networks) Shared LAN The main feature of shared LANs is that all attached components share the bandwidth of the transmission medium. At any one time, there can only be one data packet in transit through the network. All data packets pass through all segments. One station sends while all others receive. The station obtains the right to send according to the CSMA/CD medium access method.
Configuring Networks Optical Budget in SIMATIC NET Industrial Ethernet (10BASE-FL) The 10BASE-FL optical ports operate at a wavelength of 850 nm. In Industrial Ethernet, the following optical budget is available: S 50/125 µm fiber: 8 dBm S 62.5/125 µm fiber: 11 dBm This power budget can be “used up” as power loss through the fiber-optic transmission path. Optical Power Loss The optical power loss is the cumulative value of all the losses occurring in the fiber-optic transmission path.
Configuring Networks SIMATIC NET Glass Fiber-Optic Cables The SIMATIC NET product range for Industrial Ethernet includes various types of glass fiber-optic cables with 62.5/125 µm fibers (see “Passive Components for Optical Networks”). When connecting SIMATIC NET Industrial Ethernet network components linked with SIMATIC NET glass fiber-optic cables, the maximum length of the link is limited as shown in the table below: Table 3-1 Maximum length of a link with fiber type G 62.
Configuring Networks 3.1.3 AUI Links According to the “Ethernet” standard IEEE 802.3 /1/ , a maximum length of 50 m is permitted for AUI links. Note When using a CP 1511, the maximum cable length of the AUI link is restricted to 40 m! 3.1.
Configuring Networks Variability Value and Path Variability Value In a local area network complying with IEEE 802.3, two data packets must have a certain minimum gap between them. If the gap is smaller, this is known as an interframe gap error. The variability value of a component describes the fluctuations in the propagation time of a data packet through a network component. If two data packets pass through several network components one after the other, the gap between the packets is reduced.

Configuring Networks 3.2.2 Bus Structure The bus structure allows the cascading of OLMs or ELMs in series via fiber-optic cables or twisted pair. A distance of 0 to 3100 m is possible between two link modules connected by optical fiber. With TP cables, a distance of up to 100 m is possible. If a module develops a fault or there is a break on the cable, the network breaks down into two subnets. Within these subnets, problem-free operation remains possible.

Configuring Networks Notes: 3.2.5 S Each further network component increases the PVV and reduces the remaining cable length. S When cascading OLMs and ELMs using twisted-pair cables, make sure that you use a crossover cable (cable with XP identifier). This is available in lengths from 2 to 100 meters.

Configuring Networks 3.2.6 Redundant Ring Structure with OLMs This network topology is a special form of the bus topology. The first and last OLM are connected together via optical fiber and the ring is therefore closed. Port 5 of an OLM within this ring structure must be switched to the redundant mode. The line connected to port 5 then becomes a redundant line that is only used for data transmission when there is a break in the ring.
Configuring Networks Configuration Rule A maximum of 11 OLMs can be cascaded in a redundant ring; in other words, a frame can pass through a maximum of 11 OLMs when being transferred from a sending to a receiving DTE. Node 1 1 OLM Node 2 Highest bus load in network Redundant mode = ON OLM OLM OLM 1 OLM ÇÇ ÇÇÇÇÇÇÇÇÇÇÇÇÇÇÇÇÇ Ç ÇÇ Ç ÇÇ Ç ÇÇ Ç ÇÇÇÇÇÇÇÇÇÇÇÇÇÇÇÇÇÇ 200 m 400 m 500 m 5 4 600 m 2 1000 m Shortest section Redundant line 1. ITP standard cable 9/15 2.
Configuring Networks Note on OLM Version 1: Version 1 OLMs were no longer supplied from the start of 1998 ! To avoid loss of performance in redundant ring structures with OLM version 1 in the redundant mode, you must take into account the load distribution in the network. Follow the steps below: S Find out which OLM transfers the highest volume of data via its twisted pair ports into the redundant ring.
Configuring Networks 3.2.7 Combinations with Star Couplers and other Network Components S Optical interface cards ECFL2, ECFL4 OLMs can be combined with star couplers in an optical network (see Figure 3-7). A bus structure or redundant ring structure can be created with the ECFL2 or ECFL4. The maximum span of the ring depends, in this situation, on the combinations.
Configuring Networks Example The following example once again illustrates how to configure a network when mixing OSMs, OLMs, ELMs, and star couplers. The individual transmission paths must be checked. Critical paths are those in which the signal runs through long sections of cable and a lot of network components between two nodes. The connection between node 1 and node 3 represents a critical path. Node 3 is connected to OLM 4 in the redundant ring.

Configuring Networks Note If redundant rings are attached to a star coupler structure, when checking the configuration, the redundant ring must be segmented to produce a worst-case bus structure. To do this, the shortest connection from the star coupler to one of the two adjacent OLMs is interrupted.
Configuring Networks The same checks must also be performed for other paths (for example node 1 <-> node 4, node 3 <-> node 4). The configuration is only correct when the limit values are not exceeded by any of the paths. Note The path of nodes 1, 3, 4 and 5 to node 2 only needs to be checked as far as the first OSM. Due to the way in which the OSM works (“store-and-forward switching”), every collision domain ends at the port of an OSM. 3.
Configuring Networks 3.4 Configuring an Electrical 100 Mbps Switched LAN Products The following components and cables are used in a 100 Mbps switched LAN: S Components – Electrical switch module ESM S Cables – Twisted pair cable – TP cord 3.4.1 Twisted-Pair Links 100BASE-TX The twisted-pair ports of the ESM comply with the IEEE 802.3u: 100BASE-TX standard. The connectors are either sub-D-9 or RJ-45 jacks depending on the ESM variant.
Configuring Networks 3.4.2 ESM Bus Structure 100 Mbps Switched LAN with a Bus Structure The Industrial Ethernet ESMs allow the implementation of 100 Mbps switched LANs with a bus structure. The maximum distance between two ESMs must not exceed 100 m. You can cascade the modules to form a bus using any TP port. Up to a maximum of 50 ESMs can be cascaded.
Configuring Networks Note The reconfiguration time of less than 0.3 s can only be achieved when no components (for example switches from other vendors) other than ESMs are used in the redundant ring. In a ring, one device and one device only must operate in the redundancy manager mode. DTEs or complete network segments can be attached to ports 1 – 6 of an ESM operating in the RM mode.
Configuring Networks 3.5 Configuring an Optical 100 Mbps Switched LAN Products The following components and cables are used an optical 100 Mbps switched LAN: S Components – OSM (I)TPnn (with multimode glass fiber-optic cable) – OSM (I)TPnn-LD (with single mode glass fiber-optic cable) S Cables – Multimode glass fiber-optic cable type 50/125 µm or 62.5/125 µm – Single mode glass fiber-optic cable type 10/125 µm – Twisted-pair cable, TP Cord 3.5.
Configuring Networks Requirements of Single Mode Fiber-Optic Cables Single mode glass fiber-optic cables between two OSM (I)TPnn modules must meet the following requirements in terms of power loss and the bandwidth distance product: Table 3-8 Maximum length of a link with single mode FOCs between two OSM (I)TPnn-LD modules Fiber Type 10/125 µm FO Power Loss at 1300 nm Bandwidth Distance Product Max. length <=2.
Configuring Networks 3.5.2 OSM Bus Structure The Industrial Ethernet OSMs allow the implementation of 100 Mbps switched LANs with a bus structure. The maximum distance between 2 OSMs is 3000 m or 26 km for the LD variant. Modules are cascaded using the FO ports. Up to 50 OSMs can be cascaded.

Configuring Networks 3.5.3 Redundant Ring Structure with OSMs Redundant Optical Ring With the aid of an OSM functioning as the redundancy manager (RM), both ends of an optical bus made up of OSMs can be closed to form a redundant optical ring. The OSMs are connected together using ports 7 and 8. The RM monitors the OSM bus connected to it, closes the bus if it detects an interruption and therefore reestablishes a functioning bus configuration. A maximum of 50 OSMs are permitted in an optical ring.
Configuring Networks 3.6 Redundant Linking of Network Segments with OSMs/ESMs Standby-Sync Port The standby-sync port allows the connection of two Industrial Ethernet OSMs or ESMs with one operating as standby master (DIP switch ”Stby off”) and the other as standby slave (DIP switch ”Stby on”). With this mode, pairs of OSMs/ESMs can be used for redundant coupling of OSM/ESM or OLM rings.

Active Components and Topologies Overview The SIMATIC NET link modules for Industrial Ethernet allow flexible configuration of Ethernet networks complying with the IEEE 802.3 standard using fiber-optic or copper cables. The transmission rate on all interfaces is 10Mbps. The link modules are fitted on to a standard rail. The OLMs (Optical Link Modules) have three Industrial Twisted Pair (ITP) ports and two optical ports (BFOC).
Active Components and Topologies Note Since the beginning of 1998, the Optical Link Module (OLM) is supplied as version 2.0. Version 2.
Active Components and Topologies 6.1.1 Components of the Product SIMATIC NET Industrial Ethernet OLM/ELM including S Terminal block for the power supply S Description and operating instructions SIMATIC NET Industrial Ethernet OLM SIMATIC NET Industrial Ethernet ELM 6.1.2 Order number 6GK1102-4AA00 6GK1102-5AA00 Installation The SIMATIC NET Industrial Ethernet OLM/ELM is clipped on to a standard rail. The modules can be installed vertically one beside the other without gaps.
Active Components and Topologies Handling Collisions If the OLM/ELM detects a data collision, it stops transmission. During the collision, the data packet that has collided is replaced by a jam signal (0/1 bit pattern) to ensure that the DTEs recognize the collision. Auto Partitioning A breakdown on the network can be caused by jabber lockup, wire breaks, missing terminating resistors, damaged cable insulation, and frequent collisions due to electromagnetic interference.
Active Components and Topologies Jabber Lockup Protection The network can be tied up continuously with data, for example due to a defective transceiver or LAN controller. To protect the network from this situation, the OLM/ELM stops reception as follows: -- At the ITP or AUI port affected after 5.5 ms. The interruption is canceled after an idle phase of 9.6 µs. -- At the fiber-optic port affected after 3.9 ms. The interruption is canceled after 420 ms of problem-free operation. 6.1.3.
Active Components and Topologies 6.1.3.3 Functions Specific to the Fiber-Optic Interface Standardization The two fiber-optic ports on the underside of the OLM comply with the IEEE 802.3 standard: 10BASE-FL. These are implemented as two BFOC female connectors for connection of glass fiber-optic cables (62.5/125 µm or 50/125 µm). The operating wavelength is 850 nm. Fiber-Optic Monitoring The OLM monitors the connected ITP line segments for breaks using regular link test pulses.

Active Components and Topologies 6.2 Optical and Electrical Switch Modules (OSM/ESM) Figure 6-6 6.2.1 Optical/Electrical Switch Modules (OSM/ESM) Application Overview The OSM/ESM Optical/Electrical Switch Modules, version 2 allow the cost-effective installation of switched networks operating at 100 Mbps.
Active Components and Topologies There are three ways of signaling errors: 6.2.2 S via the signal contact S via SNMP (traps) S by E-mail Design Casing, Installation The Industrial Ethernet OSM and ESM has a sheet steel casing with degree of protection IP20.
Active Components and Topologies The OSM/ESM has a total of eight LAN ports. Depending on the particular variant, they have the following ports: 6.2.3 S Twisted-pair port (sub-D): 10/100BASE-TX 9-pin sub-D female connector (ITP port), automatic data rate detection (10 or 100 Mbps) for connection of TP cables (max. length 100 m) S Twisted-pair port (RJ-45): 10/100BASE-TX RJ-45 jack, automatic data rate detection (10 or 100 Mbps) for connection of TP Cords (max.
Active Components and Topologies Fast Redundancy in the Ring By interconnecting the ends of a bus using OSMs/ESMs to form a ring, reliable communication can be achieved. With an OSM/ESM in the ring, the integrated redundancy manager is activated using a DIP switch. The redundancy manager constantly monitors the operation of the network. It recognizes the failure of a section in the ring or of an OSM/ESM and activates the substitute path within a maximum of 0.3 seconds.

Active Components and Topologies 6.2.5 Redundant Ring Structure Redundant Ring Structure with OSMs With the aid of an OSM functioning as the redundancy manager (RM), the ends of an optical bus made up of OSMs can be connected together to form a redundant optical ring. The OSMs are connected together using ports 7 and 8. The RM monitors the OSM bus connected to it at ports 7 and 8 in both directions.
Active Components and Topologies Redundant Ring Structure with ESMs A redundant electrical ring can be established using ESMs in the same way. To achieve this the ESMs are connected together using ports 7 and 8. One device must be switched to the redundancy manager mode. With ESMs and a maximum of 50 devices in the ring, a reconfiguration time of less than 0.3 s can also be achieved.
Active Components and Topologies 6.2.6 Linking Subnets Using the OSM/ESM Subnets Using the OSM/ESM, it is possible to link several different Ethernet networks together. The collision domain of a subnet ends at the port of the OSM/ESM. OSMs/ESMs are ideal for structuring larger networks. Large networks are first divided into smaller units (subnets). These subnets are then connected to the OSM/ESM that not only interconnects them but also separates them in terms of load.
Active Components and Topologies 6.2.7 Redundant Linking of Subnets Using the OSM/ESM Structure of a Redundant Link Using an OSM/ESM, fast, redundant links between two Ethernet subnets or networks can be implemented. These networks can, for example, consist of redundant OSM/ESM rings. The redundant link as shown in Figure 6-12 is established on separate paths via the two TP ports (port 1) of an OSM/ESM pair.
Active Components and Topologies How Standby Redundancy Works One of the two OSMs/ESMs must be set to the standby mode by setting the DIP switch. This OSM/ESM forms the redundant link that only transfers data when the other path (main link) fails. The OSM/ESM in the standby mode receives information about the state of the main link via the synchronization connection between the standby-sync ports. If the main link fails, the redundant OSM/ESM activates the standby link within 0.3 seconds.
Active Components and Topologies ! Warning The Industrial Ethernet OSM/ESM is designed for operation with safety extra-low voltage (SELV). This means that only safety extra-low voltages (SELV) complying with IEC 950/EN 60950/VDE 0805 may be connected to the power supply terminals or the signaling contact. For more detailed information on the OSM/ESM, refer to the “Industrial Ethernet OSM/ESM” operating instructions in the appendix of this manual. 6.2.
Active Components and Topologies Web-Based Management Functions The management level of the OSM is accessible using a Web browser. Masks, filters, and ports can be configured. Diagnostics of the device and the ports is possible via the Web.

Guidelines for Installing Networked Automation Systems in Buildings 7.1 General Instructions on Networking with Bus Cables Bus (LAN) Cables in Plants Bus cables are important connections for communication between individual components of an automation system. Mechanical damage 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.
Guidelines for Installing Networked Automation Systems in Buildings 7.2 Protection from Electric Shock Twisted-Pair Signal Level The signal levels on twisted pair cables are low voltage. Correctly installed and operated twisted pair bus cables do not have dangerous electrical voltages. Nevertheless you should remember the following rules when installing the power supply for all components (DTEs, bus components, etc.) that you want to connect to twisted-pair cable.
Guidelines for Installing Networked Automation Systems in Buildings Safe Initial State of the System in Case of Faults Problems on communication connections must not be allowed to put system users at risk. Cable or wire breaks must not lead to undefined statuses in the plant or system.
Guidelines for Installing Networked Automation Systems in Buildings 7.3 Electromagnetic Compatibility of Bus Cables Electromagnetic Compatibility (EMC) Electromagnetic compatibility (EMC) is the capability of an electrical installation to function satisfactorily in its electromagnetic environment without influencing this environment and interfering with other installations and equipment belonging to it (in compliance with DIN VDE 0870).
Guidelines for Installing Networked Automation Systems in Buildings 7.3.1 Measures to Counter Interference Voltages Overview Measures are often taken to suppress interference voltages when the control system is already in operation and problems occur receiving signals. You can normally reduce the investment necessary for later restructuring of the system by remembering the following points when installing your automation system.
Guidelines for Installing Networked Automation Systems in Buildings 7.3.2 Equipotential Bonding System Aims of Bonding The noise immunity of extended electronic automation systems or, in general, information technology systems largely depends on the suitable design of the grounding and bonding system of the building.
Guidelines for Installing Networked Automation Systems in Buildings Measures for Grounding and Equipotential Bonding According to EN 50310 /21/, a “common bonding network CBN” with a fine mesh of conductive elements must be created in buildings with information technology systems. Systems that extend beyond one floor and that are interconnected by electrical bus cables require a three-dimensional CBN with a lattice construction resembling a Faraday cage.
Guidelines for Installing Networked Automation Systems in Buildings 7.3.3 Requirements of the Power Distribution System General HD 384.3 S2 (IEC 60364-3:1993, modified, /22/) describes various power distribution systems (TN-S, TN-C,S, TN-C, TT and IT systems). Additional national or local regulations stipulate the measures required for protection from electric shock and stipulate the requirements for a grounding system (see also section 7.2 protection from electric shock).
Guidelines for Installing Networked Automation Systems in Buildings Signal Connections in Existing Installations If unexplained, sporadic disturbances occur in data processing systems or on their communication connections, it is advisable to check for unwanted shield currents. These can be measured simply by inserting the cable in question in a clip-on ammeter. Currents higher than approximately 0.1 A indicate problems in the electrical installation, for example in the TN-C system.
Guidelines for Installing Networked Automation Systems in Buildings Example of Installing FOC in a TN-C-S System Figure 7-1 illustrates the relationships between the structure of the alternating current network, equipotential bonding system, and information technology cabling in a building. Three PCs and three S7-300 PLCs represent the information technology system. These are networked using two OSMs.

Guidelines for Installing Networked Automation Systems in Buildings 7.3.4 Shielding Devices and Cables Shielding Cables The high degree of noise immunity of SIMATIC NET twisted pair copper networks is achieved by the exclusive use of shielded twisted-pair cables. The highly symmetrical twisted signal wires are surrounded by a combination of foil and braided mesh shields.
Guidelines for Installing Networked Automation Systems in Buildings Handling Bus Cable Shields Note the following points about cable shields: S Use SIMATIC NET twisted-pair cables throughout your system. The shields of these cables have an adequate density to meet the legal requirements regarding noise emission and immunity. S Always contact the shields of bus cables at both ends.
Guidelines for Installing Networked Automation Systems in Buildings Establishing Shield Contact When contacting the cable shields, please note the following points: Figure 7-2 S Secure the braided shield with metal cable clamps. S The clamps must make good and large-area contact with the shield (see Figure 7-2). S Contact SIMATIC NET twisted-pair cables only using the braided copper shield and not the aluminum foil shield.
Guidelines for Installing Networked Automation Systems in Buildings S Figure 7-3 7-16 Unless specifically intended for this purpose, shield clamps and contacts should not be used for strain relief. The contact with the shielding bar could be impaired or be broken altogether.
Guidelines for Installing Networked Automation Systems in Buildings 7.3.5 Special Noise Suppression Measures Connecting Switched Inductances to Suppressors Some inductive switching devices (for example relays) create interference voltages that are a multiple of the switched operating voltage. The distributed SIMATIC S7-300 /9/ and S7-400 /10/ system manuals contain suggestions about how to limit the interference voltages caused by inductance by connecting them to suppressors.
Guidelines for Installing Networked Automation Systems in Buildings 7.4 Arrangement of Devices and Cables Adequate Clearance to Reduce the Effects of Interference One simple but nevertheless effective method of reducing the effects of interference is to keep the “culprit” and “victim” devices and cables as far apart from each other as possible. Inductive and capacative interference injection declines in proportion to the square of the distance of the elements involved.
Guidelines for Installing Networked Automation Systems in Buildings 7.4.2 Cable Categories and Clearances Fiber-Optic Cables When using fiber-optic cables, mechanical protection is necessary, however the EMC rules do not apply. Cable Groups It is useful to group wires and cables into various categories according to the signals they carry, possible interference signals, and their sensitivity to interference.
Guidelines for Installing Networked Automation Systems in Buildings How to Read the Table To check how cables of different types must be laid, follow the steps outlined below: 1. Find the cable type of the first cable in column 1 (cables for ...). 2. Find the cable type of the second cable in the relevant section in column 2 (and cables for ...). 3. Read the guidelines for laying the cables in column 3 (lay ...). Table 7-1 Cabling Within Buildings Cables for ... and cables for ...
Guidelines for Installing Networked Automation Systems in Buildings 7.4.3 Cabling within Closets When running cables within cubicles and cabinets, remember the following rules: 7.4.4 S Install the cables in metallic, electrically conductive cable channels. S Screw the cable channels to the struts of the rack or cubicle walls approximately every 50 cm making low-resistance and low-inductance contact. S Separate the cables according to the categories as shown in table 7-1 .
Guidelines for Installing Networked Automation Systems in Buildings 7.4.5 Cabling outside Buildings Using Fiber-Optic Cables Industrial Twisted Pair is intended for use within buildings (tertiary area). The installation of Industrial Twisted Pair cables between buildings in not permitted. LAN connections between buildings and between buildings and external facilities are only possible with fiber-optic cables (FO).
Guidelines for Installing Networked Automation Systems in Buildings 7.5 Mechanical Protection of Bus Cables Protection of Electrical and Optical Bus Cables Mechanical protection is required to protect bus cables from breaks or mechanical damage. Note The guidelines for mechanical protection apply both to electrical and optical cables.
Guidelines for Installing Networked Automation Systems in Buildings Figure 7-6 Interrupting the Conduit at an Expansion Joint Redundant Bus Cables The installation of redundant bus cables involves special requirements. Redundant cables should always be installed on separate cable racks to avoid simultaneous damage by the same event. Install Bus Cables Separately To prevent accidental damage to bus cables, they should be clearly visible and should be separate from all other wiring and cables.
Guidelines for Installing Networked Automation Systems in Buildings 7.6 Electromagnetic Compatibility of Fiber-Optic Cables Fiber-Optic Cables For communications 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.
Guidelines for Installing Networked Automation Systems in Buildings 7.7 Installing LAN Cables 7.7.1 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.
Guidelines for Installing Networked Automation Systems in Buildings 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.
Guidelines for Installing Networked Automation Systems in Buildings 7.8 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, fiber-optic cables must not be twisted, stretched or squashed.
Guidelines for Installing Networked Automation Systems in Buildings 7.9 Fitting Twisted Pair Connectors General To maintain the excellent EMC and transmission characteristics of the twisted-pair cabling system, connectors must be fitted with extreme care following the installation instructions exactly. How to fit 9-pin and 15-pin connectors is explained in detail on the following pages. Note Fit the sub-D connectors only to the 2x2 Industrial Twisted-Pair standard cable.

It simplifies network configuration and network expansions. The OSM Version 2/ESM are simply called OSM/ESM in the rest of this manual. The OSMs have both electrical ports and additional FO ports via which several of these devices can be interconnected to form an optical bus or ring configuration.
Introduction This manual describes the functions of the OSM/ESM available without using network management. The OSM/ESM Network Management user manual describes the additional options available if you use network management.
Introduction 1.1 Overview of the Variants of the OSM/ESM 1.1.1 OSM ITP62 Possible Attachments The OSM ITP62 allows attachment of up to 6 DTEs or network segments using the ITP connector. By coupling an OSM via ports 7 and 8 it is possible to create optical bus and ring structures. The OSM ITP62 can be coupled with other OSM ITP62, OSM ITP53 and OSM TP62 modules via the optical ports.

Functions 2 This chapter discusses the general functions of the OSM/ESM, in particular the properties of the switching technology. Increased Network Performance By filtering the data traffic based on the Ethernet (MAC) address of the DTEs, local data traffic remains local, only data intended for nodes in another network segment are passed on by the OSM or ESM. This reduces the data traffic in the network segments and lowers the network load in the network segments.
Functions Learning Addresses By evaluating the source addresses in the data packets, OSMs/ESMs automatically learn the addresses of the DTEs attached via a particular port. If an OSM/ESM receives a data packet, it directs this packet only to the port via which the appropriate DTE can be obtained. An OSM/ESM can learn up to 12000 addresses.
Functions Packets with the VLAN Priority Tag Please note the following: 1. The OSM/ESM does not support packets with VLAN tags according to IEEE 802.1Q. Configure your network so that no packets with VLAN tags are transmitted via the OSM/ESM. 2. Your network should be designed so that no packets with a priority tag and a priority higher than 3 (IEEE 802.1p) are transmitted via the OSM/ESM since these packets can influence redundancy functions (for example, longer switchover times if a fault develops).

Network Topologies with OSM/ESM 3.1 Bus Structure With OSMs or ESMs, bus structures can be implemented . The cascading depth and total span of a network are limited only by the monitoring times of the communication connections. These times must always be set higher than the signal delay of the transmission path.

(Connecting cable to couple the two variants available on request).
Network Topologies with OSM/ESM 3.2 Redundant Ring Structure With the aid of an OSM functioning as the redundancy manager (RM), both ends of an optical bus made up of OSMs can be closed to form a redundant optical ring. The OSMs are connected together using ports 7 and 8. The RM monitors the OSM bus connected to it, closes the bus if it detects and interruption and therefore reestablishes a functioning bus configuration. A maximum of 50 OSMs are permitted in an optical ring.

Network Topologies with OSM/ESM 3.3 Redundant Coupling of Network Segments The standby sync port allows the connection of two Industrial Ethernet OSMs or ESMs with one operating as standby master (DIP switch "Stby off") and the other as standby slave (DIP switch "Stby on"). With this mode, pairs of OSMs/ESMs can be used for redundant coupling of OSM/ESM or OLM rings.

Network Topologies with OSM/ESM The connection between two network segments is on two separate paths. Two of the OSMs/ESMs in a ring are connected together via a connecting cable (ITP-XP standard cable 9/9 with a maximum length of 40 m) and inform each other of their operating states. One of these OSMs/ESMs is assigned the redundant function using the DIP switch setting "Stby on" (standby slave). The other OSM takes over the function of the standby master (DIP switch setting "Stby off").
Network Topologies with OSM/ESM Redundant Coupling of Rings over Fiber Optic Cable with the OSM ITP53 The OSM ITP53 allows a redundant coupling of rings with FO transmission paths. This allows rings far apart from each to be connected.
Network Topologies with OSM/ESM 3.4 Compatibility of OSM Version 2/ESM with OSM/ORM Version 1 Compatibility Version 2 OSMs can be operated at the same time in the ring with the OSM (6GK 1105-0AA00) and ORM (6GK 1105-1AA00) here called OSM/ORM Version 1. Make sure that only one device can adopt the redundancy manager function in the ring; in other words, only one ORM or only one OSM Version 2 operating in the RM mode.

The Ethernet Planning Rules: Sum of the delay equivalents and cable lengths in the worst-case path shorter than 4520 m. Sum of the variability values in the worst-case path less than 50 bit times need only be maintained as previously in each individual segment (see also "SIMATIC NET Industrial Twisted Pair and Fiber Optic Networks" manual).

Interfaces, Displays and Operator Controls 4.1 ITP/TP Ports This chapter describes the properties of ITP and the TP ports. 4.1.1 ITP Ports In the ITP variant of the OSM/ESM, the DTEs are attached via sub-D female connectors. The casings of the connectors are electrically connected to the casing of the OSM. A screw locking mechanism holds the connectors firmly in place. RD + Pin 1 n.c. Pin 2 n.c. Pin 3 n.c. Pin 4 TD + Pin 5 Pin 6 RD Pin 7 n.c. Pin 8 n.c.
Interfaces, Displays and Operator Controls 4.1.2 TP Ports With the OSM TP62 and ESM TP80, the DTEs are attached via RJ-45 female connectors. Pin 1 RX + Pin 2 RX - Pin 3 TX + Pin 4 n.c. Pin 5 n.c. Pin 6 TX - Pin 7 n.c. Pin 8 n.c.
Interfaces, Displays and Operator Controls 4.1.3 Properties of the TP/ITP Ports Link Control OSMs/ESMs monitor the connected TP/ITP cable segments for short-circuits or wire breaks using regular link test pulses complying with the 100BASE-TX standard. OSMs/ESMs do not send data to a segment from which they are not receiving link test pulses. An unused interface is taken to be a wire break since the device without power cannot send link test pulses.
Interfaces, Displays and Operator Controls 4.1.4 FO Ports The FO ports have BFOC/2.5(ST) female connectors. They monitor the connected cable for wire breaks complying with the IEEE 802.3 100 Base-FX standard. A break on the FO cable is always signaled by the port status display of both connected OSMs. (Status LED of the port goes off).
Interfaces, Displays and Operator Controls 4.1.5 Standby Sync Port A 9-pin female connector is used to connect the ITP XP Standard Cable 9/9 for the redundant standby coupling. The casing of the connector is electrically connected to the casing of the OSM/ESM. A screw locking mechanism holds the connectors firmly in place. Stby_In + Pin 1 n.c. Pin 2 n.c. Pin 3 n.c. Pin 4 Stby_Out + Pin 5 Pin 6 Stby_In Pin 7 n.c. Pin 8 n.c.
Interfaces, Displays and Operator Controls 4.1.6 Serial Interface OSMs/ESMs have an RS-232 interface that is used for firmware updates.
Interfaces, Displays and Operator Controls 4.1.7 Signaling Contact/Terminal Block for Attaching the Power Supply The attachment of the power supply and the signaling contact is made using a 6-pin plug-in terminal block with a screw locking mechanism. L1 + +24V F1 M M F2 L2 + +24V Figure 22: Terminal Block Warning Industrial Ethernet OSMs/ESMs are designed for operation with safety extralow voltage.
Interfaces, Displays and Operator Controls Signaling Contact The following is signaled via a floating signaling contact (relay contact) when contact is broken: The failure of a monitored power supply. Which power supply is monitored is specified in the fault mask (see Section 4.2.3). The incorrect link status of a monitored port (in other words, the port is not correctly attached or there are no link test pulses coming from the partner device).
Interfaces, Displays and Operator Controls 4.2 Displays and Operator Controls The OSM/ESM has the following LED displays: 4.2.1 LED "Status" The status display indicates the operating mode of an OSM/ESM: Fault (red LED): Status Meaning Lit The OSM/ESM has detected an error. The signaling contact opens at the same time. The signaled errors are described in Chapter 4.1.7. Not lit No errors detected by the OSM/ESM.
Interfaces, Displays and Operator Controls RM – Redundancy Manager (green LED) Status Lit Meaning The OSM/ESM is operating in the redundancy manager mode. The ring is operating free of errors in other words the redundancy manager does not allow traffic through but monitors the ring. Note: One OSM must operate in the redundancy manager mode (and one only) in each OSM/ESM ring. Not lit The OSM/ESM is not in the redundancy manager mode.
Interfaces, Displays and Operator Controls 4.2.2 LED "Power" The display mode of the "Power" LED can be switched over by briefly pressing the "Select/Set" button on the front panel of the OSM/ESM. The valid display mode is indicated by the two display mode LEDs on the OSM/ESM.
Interfaces, Displays and Operator Controls 4.2.3 Port LEDs The port LEDs indicate the operating states of the individual ports of the OSM/ESM. The display mode of the port LEDs can be changed using the button on the front panel of the OSM/ESM allowing all operating states to be displayed. The current display mode is signaled by the two display mode LEDs.
Interfaces, Displays and Operator Controls Display mode Fault mask The fault mask indicates whether the ports and the power supplies are monitored with the signaling contact. Display LED on Meaning LED on Port LED - Lit green: Port is monitored; in other words, if the port does not have a valid connection (for example cable not plugged in or attached device turned off), the signaling contact is triggered.
Interfaces, Displays and Operator Controls 4.2.4 Operator Controls 4.2.4.1 Two-Pin DIP Switch With the two-pin DIP switches on the upper casing of the OSM/ESM you can do the following: With the Stby button, you can toggle the standby function on and off. With the RM switch, you can activate the redundancy manager function.
Interfaces, Displays and Operator Controls 4.2.4.2 "Select/Set" Button The "Select/Set" button on the front panel of the OSM/ESM has the following functions: Pressing the button briefly moves on the display of the port LEDs (display mode). The current display mode is indicated by the display mode LEDs. If the display is in the port status (both display mode LEDs off) and if the button is pressed for three seconds, the display mode LEDs begin to flash.

Glossary Backbone The network at the highest level of a hierarchically structured plant network. Bandwidth length product (FO) Measure of the capability of a fiber-optic cable to transfer at high data rates. Bridge A network component that interconnects network segments. This ensures that local data traffic remains local, in other words only data packets for a node in the other segment are forwarded through the bridge. Errors in a network segment are restricted to the original network segment.
Glossary Chassis ground Chassis ground includes all the interconnected inactive parts of equipment that must not have a hazardous voltage even in the event of a fault. Collision domain To ensure that the CSMA/CD protocol functions correctly, the propagation time of a data packet from one node to another is restricted. This propagation time results in a specially limited span for the network depending on the data rate known as the collision domain.
Glossary Filtering A switch filters data traffic based on source and destination addresses in a data packet.
