    1 Mbit/s. The CANopen-node number and the CAN-bit rate can be easily set via coding switches. The CAN-CBX-THERMO features the possibility to connect the power supply and the CAN bus signals via the InRailBus connector (TBUS-connector) integrated in the mounting rail. Individual modules can then be removed without interrupting the bus signals.

  • Page 11: Quick Start

    Mount the CAN-CBX-module and connect the interfaces (power supply voltage, CAN, thermocouple inputs). Please note that the CAN bus has to be terminated at both ends! esd offers special T-connectors and termination connectors. Additionally the CAN_GND signal has to be connected to earth at exactly one point in the CAN network.

    Therefore the practical maximum number of nodes, bus length and stub length are typically much lower. esd has concentrated her recommendations concerning CAN wiring on the specifications of the ISO 11898-2. Thus this wiring hints forgoes to describe the special features of the derived standards CANopen, ARINC825, DeviceNet and NMEA2000.

    6.2.1 General Rules NOTICE esd grants the EU Conformity of the product, if the CAN wiring is carried out with at least single shielded single twisted pair cables that match the requirements of ISO 118982-2. Single shielded double twisted pair cable wiring as described in chapter 6.3 ensures the EU Conformity as well.

    In principle the CAN bus has to be realized in a line. The participants are connected to the main CAN bus line via short cable stubs. This is normally realised by so called T-connectors. esd offers the CAN-T-Connector (Order No.: C.1311.03)

  • Page 38: Heavy Industrial Environment (Double Twisted Pair Cable)

    Select a working combination of bit rate and cable length. Keep away CAN cables from disturbing sources. If this cannot be avoided, double shielded cables are recommended.
