  • Page 17: Basic Function Principles Of Ethercat Junctions

    Basic function principles of EtherCAT junctions Basic function principles of EtherCAT junctions Some Beckhoff EtherCAT devices can be used for junctions in the EtherCAT segment. These include EK1122, EK1521, EP1122, CU1128 and EP9128. In the following examples only the EK1122 is used. The technical and system characteristics of the other devices are similar.

  • Page 19 Basic function principles of EtherCAT junctions Implementation: EL terminal A standard EtherCAT slave  such as a Beckhoff EL terminal has 2 ports: • one for incoming frames (port 0 [A]) • one for outgoing frames (e.g. port [D]). The other two ports are internally closed in the ESC. An EtherCAT telegram enters the processing unit via port 0 (A)/top and is forwarded to the next slave via port 3 (D)/left, if a link to this port exists - see green arrows.
  • Page 20 The wiring diagram is shown in the TwinCAT online topology, see Fig. Online topology. The EK1122 is selected, so that further information is shown. The green bars above the slaves indicate the correct RUN state in all slaves. Version: 1.5 EP1122-0001...
  • Page 21 This has the effect that the next incoming EtherCAT telegram is immediately forwarded to port D (port 3) and the EL4732. The link is missing here; the System Manager indicates this in the online display, see Fig. Example configuration with interrupted cable. EP1122-0001 Version: 1.5...
  • Page 22 The logger output can be displayed in the lower part of the System Manager (Display--> Show Logger Output). This may be helpful for diagnostic purposes (for link interruptions and other situations). In the topology view this interruption is indicated by a red border around the affected slaves, see figure below. Version: 1.5 EP1122-0001...
  • Page 23 - all slaves are operating properly. The image on the right shows a significant increase (currently 77 acyclic frames/sec): The EtherCAT master has quickly detected that not all slaves are properly taking part in the data exchange. Once the master has located the fault, it continuously tries to restore the connection. EP1122-0001 Version: 1.5...

    Associated and synonymous with each revision there is usually a description (ESI, EtherCAT Slave Information) in the form of an XML file, which is available for download from the Beckhoff web site. From 2014/01 the revision is shown on the outside of the IP20 terminals, see Fig. “EL5021 EL terminal, standard IP20 IO device with batch number and revision ID (since 2014/01)”.

  • Page 43: Version Identification Of Ip67 Modules

    Version identification of IP67 modules The serial number/ data code for Beckhoff IO devices is usually the 8-digit number printed on the device or on a sticker. The serial number indicates the configuration in delivery state and therefore refers to a whole production batch, without distinguishing the individual modules of a batch.

  • Page 44: Beckhoff Identification Code (Bic)

    7.3.3 Beckhoff Identification Code (BIC) The Beckhoff Identification Code (BIC) is increasingly being applied to Beckhoff products to uniquely identify the product. The BIC is represented as a Data Matrix Code (DMC, code scheme ECC200), the content is based on the ANSI standard MH10.8.2-2016.
  • Page 45 Fig. 20: Example DMC 1P072222SBTNk4p562d71KEL1809 Q1 51S678294 An important component of the BIC is the Beckhoff Traceability Number (BTN, position 2). The BTN is a unique serial number consisting of eight characters that will replace all other serial number systems at Beckhoff in the long term (e.g.

  • Page 46: Electronic Access To The Bic (Ebic)

    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 47 • For processing the BIC/BTN data in the PLC, the following auxiliary functions are available in Tc2_Utilities from TwinCAT 3.1 build 4024.24 onwards ◦ F_SplitBIC: The function splits the Beckhoff Identification Code (BIC) sBICValue into its components based on known identifiers and returns the recognized partial strings in a structure ST_SplitBIC as return value.
