  • Page 8: Product Overview

    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.

    The principle of the Bus Terminal Fig. 1: The principle of the Bus Terminal The Beckhoff Bus Terminal system Up to 256 Bus Terminals, with 1 to 16 I/O channels per signal form The Bus Terminal system is the universal interface between a fieldbus system and the sensor / actuator level.
  • Page 10 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 16: 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 17: 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. BC8050 und BC8150 Version: 3.0.0...

  • Page 18: 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.

  • Page 19: Power Supply

    The connection is made by means of the upper spring-loaded terminals labelled 24 V and 0 V. This supply voltage is used for the electronic components of the Bus Coupler / Bus Terminal Controllers and (via the K- bus) the electronic components of the Bus Terminals. It is galvanically separated from the field level voltage. BC8050 und BC8150 Version: 3.0.0...

    The current load from the power contact must not exceed 10 A for long periods. The current carrying capacity between two spring-loaded terminals is identical to that of the connecting wires. Version: 3.0.0 BC8050 und BC8150...

  • Page 21: Programming Cable

    Do not interrupt the ground connection for the supply voltage When the programming cable (between BCxx50 and PC) is connected, the ground connec- tion of the Bus Terminal controller must not be interrupted or disconnected, since this may Attention destroy the programming cable.
