CANopen

The CANopen Bootloader protocol stack provides the complete functionality for integration of a bootloader according to the CANopen standard in your existing devices. Versatile configuration options facilitate individual customization to a target product. The Bootloader was implemented to meet low storage requirements. The CANopen Bootloader stack comprises a reduced object dictionary and supports NMT, SDO (Expedited/Segmented/Block), Emergency, Heartbeat as well as LSS services. Up to four separate sections for storage of programmes and data may be defined. The CANopen Download Tool is used to update programmes and data of the target hardware. A defined API facilitates adjustment to a flash memory of the target hardware. Flash drivers for various controllers (e.g. STM32 series) are part of the CANpie driver.

Varying ambient temperatures from cold winters to summer heat, resistance against environmental influence, such as shock or vibration – these are the main requirements for agricultural technology. Before these vehicles go into series production, they are thoroughly tested in extreme conditions – day and night. In tough test applications, the CAN bus technology from MicroControl ensures reliable data transfer between vehicle components and the testing facility.

The µCAN.1.ti-BOX is the single channel solution for measuring temperatures. Resistance sensors as well as thermocouples may be connected to the module. The CAN interface supports the protocol CANopen.Temperature Thermo type J, K, L Temperature Pt100 (2- / 4-core) Accuracy +/- 0.5 K (Thermo) Accuracy +/- 0.1 K (Pt100) Resolution 16-bit (0.1 °C) Sampling rate 20 ms / 50 Hz galvanically isolated fieldbus Signal type freely configurable Electronics protected up to 40 G (option) Vibration resistant up to 4.5 Grms (option) Fieldbus CAN Protocol CANopen / Raw CAN

At its eight outputs the µCAN.8.pwm-BOX provides pulse width modulated signals (PWM) within a range of 0% to 100% for controlling of actuators (valves etc.). The outlets are overload and short circuit protected. The µCAN.8.pwm-BOX is connected with the central control unit via CAN bus.PWM output Basic frequency 40 Hz … 5 kHz Mark-to-space ratio 0.0 % … 100.0 % Galvanically isolated fieldbus Each output to be charged with max. 1.4 A 3-wire connector terminal Output drivers supplied separately Status indication at each output Protected against mechanical impact Fieldbus CAN Protocol CANopen / Raw CAN
