PROFIBUS networks 1.1 Local area networks in manufacturing and process automation 1.1.1 General introduction 1 Communications 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 highperformance communication system.
PROFIBUS networks 1.1 Local area networks in manufacturing and process automation The basis of such communication systems is provided by local area networks (LANs) that can be implemented in one of the following ways depending on certain conditions: ● Electrically ● Optically ● Wireless ● Combined electrical/optical/wireless ● Electrically, intrinsically safe 1.1.
PROFIBUS networks 1.1 Local area networks in manufacturing and process automation 1.1.3 Bus systems for industrial use Overview The following graphic shows the connection of the various automation systems to the standardized networks.

PROFIBUS networks 1.1 Local area networks in manufacturing and process automation PROFINET IO PROFINET allows the integration of distributed field devices (IO devices, for example signal modules) directly in Industrial Ethernet. The user data is transferred by means of TCP/IP or IT standards. The simple engineering for PROFINET, field-proven with PROFIBUS, was adopted here. By retaining the device model of PROFIBUS, the same diagnostics information is available on PROFINET.
PROFIBUS networks 1.2 Basics of the PROFIBUS network 1.2 Basics of the PROFIBUS network 1.2.1 Attachable systems IEC 61158-2 / EN 61158-2 SIMATIC NET PROFIBUS products and the networks created with them comply with the PROFIBUS standard IEC 61158-2 / EN 61158-2. The SIMATIC NET PROFIBUS components can also be used with SIMATIC S7 to create a SIMATIC MPI subnet (MPI = Multipoint Interface). 1.2.
PROFIBUS networks 1.2 Basics of the PROFIBUS network 1.2.3 Access mechanism TOKEN BUS/masterslave method Network access on PROFIBUS corresponds to the method specified in IEC 61158-2 / EN 61158-2, "Token Bus" for active and "masterslave" for passive stations.
PROFIBUS networks 1.2 Basics of the PROFIBUS network 1.2.4 Protocols for PROFIBUS Potential applications for PROFIBUS DP PROFIBUS DP (distributed I/O) is used for controlling sensors and actuators using a central controller in production engineering. Here, particular emphasis is on the many standard diagnostics options. Other potential uses include the connection of "distributed intelligence", in other words the internetworking of several controllers (similar to PROFIBUS FMS).
PROFIBUS networks 1.2 Basics of the PROFIBUS network DP protocol At the field level, protocols for PROFIBUS with large numbers of services or complicated data processing are unsuitable because the required bus cycle time and reaction time cannot be achieved. To be able to cover the field level within the automation hierarchy, PROFIBUS DP (distributed peripheral I/O) was developed. The essential characteristic of PROFIBUS DP is that the user data is represented in the form of a cyclic data image.
PROFIBUS networks 1.2 Basics of the PROFIBUS network S7 protocol All SIMATIC S7 and C7 controllers have integrated S7 communication services that allow the user program to read or write data. The S7-400 controllers use SFBs, the S7-300 or C7 controllers use FBs. These functions are available regardless of the bus system used, so that you can use S7 communication via Industrial Ethernet, PROFIBUS or MPI. Benefits: The S7 protocol is supported by all available S7 controllers and communications processors.
PROFIBUS networks 1.2 Basics of the PROFIBUS network The attachment of the node to the bus is via a bus terminal with a spur line or a bus connector (maximum 32 nodes per segment). The individual segments are connected via repeaters.
PROFIBUS networks 1.2 Basics of the PROFIBUS network Note The properties listed in the table above assume a bus cable of type A and a bus terminator according to the PROFIBUS standard IEC 61158-2 / EN 61158-2. The SIMATIC NET PROFIBUS cables and bus connectors meet this specification. If reductions in the segment length are necessary when using special versions of the bus cable with increased loop resistance, this is pointed out in the sections on "Configuration" and "SIMATIC NET PROFIBUS cables". 1.2.5.

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 end devices are attached to the electrical interfaces of the OLMs.
Topologies of SIMATIC NET PROFIBUS networks 2.2 Topologies of optical networks Star topologies with OLMs Several optical link modules are grouped together to form a star coupler via a bus connection of the RS485 interfaces.

Network configuration 3.1 Configuring electrical networks 3.1.1 Overview 3 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.
Network configuration 3.1 Configuring electrical networks For a cable terminator to work it must be supplied with power. This means that the relevant end device or RS-485 repeater must be supplied with power. As an alternative, the PROFIBUS terminator can be used as permanent cable terminator. Note The power supply to terminating resistors must not be interrupted by turning off the end device or repeater or by unplugging the bus connector or spur line.

Network configuration 3.1 Configuring electrical networks 3.1.5 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 RS485 repeaters to form a network. The following figure shows a possible combination of several segments using repeaters to form a network. The RS-485 repeaters support all transmission speeds from 9.6 kbps to 12 Mbps.
Network configuration 3.2 Configuring optical networks Configuration When configuring an electrical network with RS485 repeaters, the following conditions must be taken into account: ● The maximum segment length for a transmission speed must be adhered to (see section Segments for transmission speeds up to a maximum of 500 kbps (Page 42), section Segments for a transmission speed of 1.5 Mbps (Page 43), section Segments for transmission speeds up to a maximum of 12 Mbps (Page 46)).
Network configuration 3.2 Configuring optical networks Transmission link An optical transmission path consists of a transmitter, the optical fiber, and a receiver.
Network configuration 3.2 Configuring optical networks ● With glass optical fibers, the number of splices (including repair splices) ● The length of the optical fiber (cable length) ● The link power margin on the link (for example for aging and temperature dependency of the LEDs and photodiodes). 3.2.
Network configuration 3.2 Configuring optical 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 transmit power that can be coupled into the fiber type.
Network configuration 3.2 Configuring optical networks System reserve 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 calculated link power margin is lower, the transmission path will not be reliable longterm in its currently planned form.

The busspecific configuration begins with the creation of the system overview in the hardware configuration dialog "HW Config" of STEP 7.
Network configuration 3.3 Frame transmission time Setting the PROFIBUS properties In the "Properties - PROFIBUS" dialog, you can set the highest station address (HSA), the transmission speed and the bus profile.

Network configuration 3.3 Frame transmission time 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 additional delays of OLM and FO cables mean that the system would exceed the value, the parameters are adapted. The newly calculated bus parameters are displayed in the "Bus Parameters" dialog. Figure 3-6 3.3.
Network configuration 3.3 Frame transmission time An unused address lower than the HSA The value of the HSA (Highest Station Address) parameter must be set on all end devices so that there is at least one address in the network between bus address 0 and the value of HSA that is not used by a node; in other words, there is an address gap. You can create this address gap simply by increasing the value of the HSA parameter to one higher than the highest node address in the network.

Lightning and overvoltage protection of bus cables between buildings B.1 B Why protect your automation system from overvoltage? Introduction One of the most common causes of hardware failures is overvoltage, caused by the following: ● Switching in power networks ● Atmospheric discharge or ● Electrostatic discharge We will show you how to protect devices attached to a PROFIBUS bus cable from overvoltages.
Lightning and overvoltage protection of bus cables between buildings B.2 Protecting bus cables from lightning Bus cables between buildings Since bus 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 bus cables are implemented in two different components, coarse protection and fine protection.
Lightning and overvoltage protection of bus cables between buildings B.3 Instructions for installing coarse protection B.3 Instructions for installing coarse protection Basic protection The coarse protection must be installed at the point where the bus cable enters the building and connected to the building equipotential bonding system with low impedance. The following are required to create the coarse protection: ● The base section type no. 919506, ● The protection module type B, type no.
Lightning and overvoltage protection of bus cables between buildings B.4 Instructions for installing fine protection B.4 Instructions for installing fine protection Low-voltage protection The fine protection should be installed as close as possible to the 1st node following the coarse protection. The following are required to install the fine protection: ● The base section type no. 919506, ● The protection module MD/HF type no. 919570, and ● The shield contact terminals type no. 919508 are required.
Lightning and overvoltage protection of bus cables between buildings B.5 General information on the lightning protection equipment from the firm of Dehn & Söhne B.5 General information on the lightning protection equipment from the firm of Dehn & Söhne ● When installing the modules read the instructions regarding the products from Dehn & Söhne. ● If there is a fault in a lightning protection module, communication on the bus is interrupted (cable shortcircuit).
Installing bus cables C.1 C Bus cables in automation systems Bus cables as important plant connections In automation systems, the bus 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 bus cables C.3 Mechanical protection of bus cables Line voltage Between components operated on mains power supply and the PROFIBUS interface, the requirements of safe electrical isolation from the power supply complying with DIN VDE 0160 and DIN IEC 60950 (Page 337) / VDE 0805/EN 60950/ UL 1950/ CSA 22.2 No. 950 must be met.
Installing bus cables C.3 Mechanical protection of bus cables Figure C-1 Mechanical protection of the bus cable Figure C-2 Interrupting the conduit at an expansion joint Bus Terminal RS485 The installation of electrical bus cables in a protected area is supported by the use of the RS485 bus terminal. This allows the attachment of end devices and service and commissioning work on the end devices without needing to move the actual bus cable.
Installing bus cables C.4 Electromagnetic compatibility of fiberoptic cables 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. To improve EMC, it is often advisable to install the bus cables in a separate cable channel or in conductive metal tubes. Such measures also make it easier to localize a faulty cable. C.
Installing bus cables C.6 Electromagnetic compatibility of bus cables Fitting strain relief Although the BFOC connectors have their own strain relief and kink protection, it is advisable to arrange for additional strain relief as close as possible to the connected device to protect against mechanical strain. Plan adequate attenuation reserves When installing the cables over long distances, it is advisable to include one or more future repair splices in the power loss budget.
Installing bus cables C.6 Electromagnetic compatibility of bus cables C.6.1 Measures to counter interference voltages Overview Measures to suppress interference voltages are often only implemented when the control system is already in operation and proper reception of a useful signal is impaired. Expenditure and effort involved in such measures (for example special relays) can be reduced considerably when installing the control system by taking into account the following points.
Installing bus cables C.6 Electromagnetic compatibility of bus cables Cable Shields Note the following points about cable shields: ● Use SIMATIC NET PROFIBUS cables throughout your system. The shields of these cables have an adequate shield density to meet the legal requirements regarding noise emission and immunity. ● Always contact the shields of bus cables at both ends.
Installing bus cables C.6 Electromagnetic compatibility of bus cables ● Contact the shield with the shielding bar directly at the point at which the cable enters the cabinet. Figure C-3 Securing shielded cables with cable clamps and ties (schematic representation) ● When removing the sheath of the cable, make sure that the braid shield of the cables is not damaged.
Installing bus cables C.6 Electromagnetic compatibility of bus cables C.6.4 Equipotential bonding When do potential differences occur? Potential differences can, for example, be caused by different power supplies. Potential differences between separate parts of the plant can be damaging to the system in the following situations: ● Programmable controllers and peripheral devices are linked on grounded connections ● Cable shields are contacted at both ends and grounded to different parts of the plant.
Installing bus cables C.7 Routing electrical bus cables bonding conductor (equivalent copper crosssectional area ≥10 mm2) must be installed parallel to the cables. This bonding conductor is not necessary if metal, conducting cable channels/racks are used. Note Bonding conductors are unnecessary if the sections of a system are connected exclusively using fiberoptic cable (FO). C.7 Routing electrical bus cables Voltages and currents Wiring and cables in a system conduct voltages and currents.
Installing bus cables C.7 Routing electrical bus cables Constraints 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 consumers connected to the cable.

Installing bus cables C.7 Routing electrical bus cables C.7.3 Cabling within buildings What do I need to remember? When laying cables outside cabinets but within buildings, note the following points: ● The clearances listed in Section "Cable categories and clearances (Page 268)" must be maintained between the various cable categories and when laying cables on common cable racks ● If the cables are laid in metal cable channels, the channels can be arranged directly beside each other.
Installing bus cables C.7 Routing electrical bus cables ● Electrical bus cables installed outside buildings must be included in the lightening protection and grounding concept of the entire system. Please note the information in Appendix "Lightning and overvoltage protection of bus cables between buildings (Page 253)" of this manual. ● All SIMATIC NET PROFIBUS cables can be used if they are installed in cable channels protected against dampness.
Installing bus cables C.8 Laying bus 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 the figure below. Shielded cable Metalencased switch Power supply filter or shielded power cable Figure C-5 C.
Installing bus cables C.8 Laying bus cables Tensile strength The tensile force exerted on the cables during or after installation must not exceed the limits of tensile strength of the cables. The permitted tensile loading on your bus cable can be found in the technical data sheets of the bus cables (see Cables for PROFIBUS RS485 networks (Page 113)). Pull cables using cable grips and protect connectors To pull cables, make sure that you use cable grips.
Installing bus cables C.8 Laying bus cables Bending radiuses To avoid damage within the bus cables, they must at no time be bent more sharply than the minimum bending radius. Please note: ● When pulling in cables under tensile load, much larger bending radii must be adhered to than when the cable is in its final installed position. ● Bending radii for non-circular cables apply only to bending the flat, broader surface. Bends in the narrower surface require much greater radii.
