    Temposonics MH Digital ® Operating Manual 4.3 Bus termination / Network connection In a 2-wire bus system like a CAN bus, serial data transmission is used, whereby the voltage difference between CAN_HI and CAN_LO is the bit information. To attenuate signal reflections at the open end of the bus, the data lines must be connected using a 120 Ω terminating resistor. The resistor should be inserted between the CAN_HI and CAN_LO data lines.

    Temposonics MH Digital ® Operating Manual 7. CAN Bus protocols The ISO 11898 international standard CAN bus (Controller Area Network) is a machine level, open field bus for fast serial data transfer between a central process control system (master) and decentralized intelligent field instruments (slaves). Various protocols, which have been developed for a variety of applications and by different user groups can be used for data transfer.

  • Page 16: Starting The Operation

    Temposonics MH Digital ® Operating Manual SAE J1939 SAE J1939 is provided with extended message arbitration. Compared to CANopen, the message identifier has been extended to 29 bits. Due to this protocol extension, different message prioritization and assignment of bus sharing units is implemented. For large quantities of data, in particular, utilization of a separate transport protocol is possible.
  • Page 17 Temposonics MH Digital ® Operating Manual Setting the Node ID A number (node ID) must be assigned to each node. The number is used for identification of the node in a CANopen network. Each individual node ID must be unique. The node ID CANopen is within a range of 1- 127, the node id CANopen Safety is within a range of 0 - 64, and can al- ready be preset when ordering.

    Temposonics MH Digital ® Operating Manual 10.2 System start CANopen & CANopen Safety After configuration of the node parameters, the sensor can be integrated into the network. When switching on, or after reset, the sensor under- goes hardware initialization. During this procedure, all components are set into a defined initial state. Subsequently, the sensor loads the instru- ment and communication-specific parameters from an EEPROM and saves them for configuration.

  • Page 20: Setting The Operating Parameters

    Temposonics MH Digital ® Operating Manual 10.3 Setting the operating parameters CANopen & CANopen Safety At system start-up (power-on, reset), the sensor saves the operating parameters stored in the EEPROM. When switching on, these are the fac- tory-set parameters, or the data which has already been changed and saved. Changes are made e.g. via SDOs when the pre-operational mode is activated.

    Temposonics MH Digital ® Operating Manual SAE J1939 The SAE J1939 sensor operating parameters can be set analogously to the CANopen sensor. The sensor can receive configuration messages during operation and saves the settings immediately after receiving the message. The following operating parameters are configurable: Cycle Time (Transmission Repetition Rates) The transmission Repetition Rate (Update Rate) is the interval at which a new position value is available at the sensor output.
