    Electronic access to the BIC (eBIC) Electronic BIC (eBIC) The Beckhoff Identification Code (BIC) is applied to the outside of Beckhoff products in a visible place. If possible, it should also be electronically readable. Decisive for the electronic readout is the interface via which the product can be electronically addressed.

  • Page 38: Principles Of Fiber-Optic Technology

    Commissioning/application notes 3.3.1 Principles of fiber-optic technology When using fiber-optic cables for the transmission of data, there are various factors that influence the signal transmission and have to be observed in order to guarantee reliable transmission. Important principles of fiber-optic technology are described below. Attenuation Less light reaches the end of a connection with fiber-optic cables than is input at the start of the connection.
  • Page 39 Commissioning/application notes Further influences on the signal transmission In addition to the main influences (attenuation and dispersion) that limit the transmission link, care must be taken when installing and maintaining fiber-optic transmission links. Sharp kinks and micro-bends in the fiber-optic lead to additional reflections in the fiber, as a result of which the influences of the attenuation and dispersion are increased.
  • Page 40 In the next step, the attenuation budget, i.e. the attenuation over the entire transmission link, must be calculated. A multimode fiber in the strength 50/125 µm from Beckhoff (ZK1091-1001-xxxx) is used for this example. A maximum attenuation of 0.8 dB/km at a wavelength of 1300 nm is specified in the data sheet for the fiber-optic cable.
  • Page 41 Commissioning/application notes Attenuation budget Parameter Number Value Fiber loss attenuation (0.8 dB/km) 2.1 km 1.68 dB Connector insertion attenuation 0.5 dB (0.25 dB) Splice insertion attenuation (0.3 dB) 0.9 dB Attenuation budget 3.08 dB If the attenuation budget is now subtracted from the power budget, a power buffer of 4.42 dB results. This is greater than 3 dB and is therefore sufficient as a buffer for most applications, so that an additional splice or slight soiling of the fiber would not lead to failure of the data transmission.
  • Page 42 Commissioning/application notes Evaluation of a fiber-optic transmission link by means of measurement A fiber-optic transmission link can be described and evaluated with parameters from data sheets. In order to obtain a real result for the attenuation over the entire link, however, the link must be measured using an optical power meter (OPM).

    Please refer to the EtherCAT System Documentation for the EtherCAT fieldbus basics. Basic function principles of EtherCAT junctions Some Beckhoff EtherCAT devices can be used for junctions in the EtherCAT segment. These include EK1122, EK1521, EP1122 or also CU112x. In the following examples only the EK1122 is used. The technical and system characteristics of the other devices are similar.
  • Page 84 Basics • this frame passes each slave once, • is reversed by the last slave in the logical sequence • and is returned to the master through each EtherCAT slave via two return lines of the Ethernet cable without further processing. At short cycle times in the order of 50 µs at 20,000 Ethernet frames are in transit in the EtherCAT system every second, plus acyclic organizational frames.
  • Page 85 Ethernet frame is in transit on this line and in the bus segment downstream of the separation point. Implementation: EL terminal A standard EtherCAT slave such as a Beckhoff EL terminal has two ports: • one for incoming frames (port 0 [A]) • and one for outgoing frames (e.g. port [D]).
  • Page 86 Basics Implementation: EK1121-0010 EtherCAT junction, Extended Distance As in the EK1100, three ESC ports can be connected in these junctions: Two via E-bus within the terminal and one via the RJ45 sockets with Ethernet configuration. Implementation: EK1122 EtherCAT junction In the EK1122 all four ESC ports can be connected - two via the internal E-bus and two via the RJ45 sockets with Ethernet configuration.

    NOTICE Only use TwinCAT 3 software! A firmware update of Beckhoff IO devices must only be performed with a TwinCAT 3 installation. It is recommended to build as up-to-date as possible, available for free download on the Beckhoff website. To update the firmware, TwinCAT can be operated in the so-called FreeRun mode, a paid license is not required.
  • Page 95 Appendix Above all, each EtherCAT slave carries its device description (ESI) electronically readable in a local memory chip, the so-called ESI EEPROM. When the slave is switched on, this description is loaded locally in the slave and informs it of its communication configuration; on the other hand, the EtherCAT master can identify the slave in this way and, among other things, set up the EtherCAT communication accordingly.
