  • Page 33 Handling bus cable shields Note the following points about cable shields: ● Use shielded 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.
  • Page 34 ● The clamps must make good and largearea contact with the shield. ● Contact SIMATIC NET PROFIBUS cables only using the braided copper shield and not the aluminum foil shield. The foil shield is applied on one side to a plastic foil to increase tearing strength and is therefore non-conductive.

    Planning/configuring Network topologies 7.1.1 Possible network topologies The following network topologies can be implemented with the PROFIBUS OLM: ● Point-to-point connection ● Bus topology ● Star topology ● Redundant optical ring Combinations of these basic types are also possible. To set up the fiber-optic links of these network topologies, cables with two optical fibers are used.

    Planning/configuring 7.1 Network topologies 7.1.3 Bus topology In a bus (linear) structure, the individual PROFIBUS OLMs are connected by two-fiber cables. At the beginning and at the end of a line, modules with one optical channel are adequate, in between modules with two optical channels are necessary.

  • Page 55 Planning/configuring 7.1 Network topologies Bus topology with fiber-optic link monitoring and segmentation Use this mode especially when you want a disrupted fiber-optic cable segment to be separated from the rest of the network, see section "Setting the mode of the electrical channel (CH1) (Page 23)"...
  • Page 56 Planning/configuring 7.1 Network topologies Note Protect the optical channels that are not connected against external light and pollution by protective caps. Bus topology without fiber-optic link monitoring Use this mode when you connect a PROFIBUS OLM with a different fiber-optic component according to the PROFIBUS guideline (optical/electrical converter), which does not send a frame echo and does not expect or tolerate a frame echo.

  • Page 57: Star Topology

    Planning/configuring 7.1 Network topologies 7.1.4 Star topology Several modules are grouped together to form an active PROFIBUS star coupler. Further modules are connected to this via two-core fiber-optic cables. The modules of the star coupler are interconnected via the electrical channel (electrical star segment). All OLM types for different fiber-optic cables (plastic, PCF, glass) can be combined via the electrical star segment.
  • Page 58 Planning/configuring 7.1 Network topologies To set up an active PROFIBUS star coupler, modules with one or two optical channels can be used. To connect an end device or an RS-485 bus segment to an active star coupler, modules with one optical channel are adequate. When the monitoring is active on the optical channels, the fiber-optic links are monitored by the connected OLMs.

  • Page 59: Ring Topology

    Planning/configuring 7.1 Network topologies 7.1.5 Ring topology 7.1.5.1 Redundant optical ring This network topology is a special form of the bus topology. "Closing" the optical bus achieves high operational reliability in the network. A redundant optical ring can only be implemented using modules with two optical channels.
  • Page 60 Planning/configuring 7.1 Network topologies The problem is indicated by the LEDs of the two OLMs connected to the disrupted fiber-optic link and by the signaling contacts of these OLMs. The segmentation is canceled automatically as soon as both modules recognize that the segmented fieldbus (sub)network is no longer disrupted based on test frames that they send out automatically.

  • Page 61: Redundant Optical Ring With Two Olms

    Planning/configuring 7.1 Network topologies NOTICE Functional disruption due to incorrect transmission medium No plastic fiber-optic cable may be connected to an OLM that uses glass fiber-optic cable and vice versa. 7.1.5.2 Redundant optical ring with two OLMs Setting up a redundant optical ring with two PROFIBUS OLMs can be seen as special case of the redundant optical ring and can be implemented with the following two configurations.
  • Page 62 Planning/configuring 7.1 Network topologies How the LEDs react in the redundant optical ring A frame received by any channel is passed on to all other channels. If the frame was received on an optical channel, it will also be sent back to the sender on the same channel as an echo and therefore serves as a monitoring frame to test the fiber-optic link between the OLMs.

  • Page 64 Planning/configuring 7.1 Network topologies 2. The redundant optical ring consists of exactly two OLMs and both fiber-optic cable connections are of exactly the same length. Under these circumstances, the receiving OLM receives a frame on both of the optical channels at the same time. To handle this case, the OLM prioritizes the two optical channels. By definition, the frame on one optical channel will then be taken as an echo (channel LED = off) and the frame on the other optical channel will then be taken as a forwarded frame (channel LED = yellow).

  • Page 65: Configuration

    Planning/configuring 7.2 Configuration Configuration Due to the delays caused by cables and network components and the monitoring mechanisms in the network components, the PROFIBUS network parameter "Slot Time" must be adapted to the network span, the network topology and the data rate. 7.2.1 Configuring optical bus and star topology The PROFIBUS network is configured, for example, in SIMATIC STEP 7 (V5 or higher),...

  • Page 67 Planning/configuring 7.2 Configuration 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 RS485 bus segment. Longer RS- 485 bus segments must be included by adding them to the Length Note If the slot time is configured with a value that is too low, this can lead to malfunctions and error displays on the OLM.
