    The BCxx50 devices are programmed according to the powerful IEC 61131-3 standard. Like for all other BECKHOFF controllers, the TwinCAT automation software is the basis for parameterization and programming. Users therefore have the familiar TwinCAT tools available, e.g. PLC programming interface, System Manager and TwinCAT Scope.

  • Page 13: The Beckhoff Bus Terminal System

    Bus Couplers for all usual bus systems The Beckhoff Bus Terminal system unites the advantages of a bus system with the possibilities of the compact series terminal. Bus Terminals can be driven within all the usual bus systems, thus reducing the controller parts count.
  • Page 14 When converting to a different bus system it is necessary to bear in mind the need to change the timeout periods if the bus cycle time is longer. The interfaces A Bus Coupler has six different methods of connection. These interfaces are designed as plug connectors and as spring-loaded terminals. Version: 2.1.0 BC3150...

  • Page 15: Mounting And Wiring

    3.1.1 Dimensions The Beckhoff Bus Terminal system is characterized by low physical volume and high modularity. When planning a project it must be assumed that at least one Bus Coupler and a number of Bus Terminals will be used. The mechanical dimensions of the Bus Couplers are independent of the fieldbus system.

  • Page 16: Installation

    The spring-loaded terminal is opened with a screwdriver or rod, by exerting gentle pressure in the opening above the terminal. The wire can be inserted into the terminal without any force. The terminal closes automatically when the pressure is released, holding the wire safely and permanently. Version: 2.1.0 BC3150...

  • Page 17: Wiring

    3.2.1 Potential groups, insulation testing and PE Potential groups A Beckhoff Bus Terminal block usually has three different potential groups: • The fieldbus interface is electrically isolated (except for individual Low Cost couplers) and forms the first potential group. • Bus Coupler / Bus Terminal Controller logic, K-bus and terminal logic form a second electrically isolated potential group.

    Activate the configuration and start the system. The TwinCAT icon (bottom right on the desktop) should be green. The bus LED of the BC3150 must light up green. Should this not be the case, check the BC3150 address and the physical connection to the PROFIBUS master (terminating resistors etc.).

  • Page 94: Switching Between Controllers

    For the standard Bus Terminal Controllers (BCxx00) it was possible to select whether a Bus Terminal is assigned to the fieldbus or the local PLC. In the default configuration of the BCxx50/BCxx20 all Bus Terminals are assigned to the local PLC. An assignment to the fieldbus is not possible in this case. Version: 2.1.0 BC3150...
