Transmission Console

CAN & CANopen Studio includes a comprehensive transmission station for injecting frames and testing network reactions.

1. Network Management (NMT) Master

Control any node on the CANopen network (Node 1 to 127) or broadcast to all nodes (Node 0):

  • Start Node (0x01): Transitions node into Operational state (enables PDO transmission and drive output).
  • Stop Node (0x02): Transitions node into Stopped state (disables PDOs, only NMT commands accepted).
  • Enter Pre-Operational (0x80): Transitions node into Pre-Operational (enables SDO configuration, disables PDOs).
  • Reset Node (0x81): Hardware reset and reboot of target device.
  • Reset Communication (0x82): Resets communication parameters to factory defaults.

2. Periodic Generators

  • High-Precision SYNC Generator: Emits CANopen SYNC pulses (COB-ID 0x080) at a user-defined frequency (default: 50 Hz / 20 ms).
  • Heartbeat Generator: Emits NMT Master heartbeat frames to keep slave nodes in active communication.

3. Arbitrary Frame Transmitter

Send custom CAN frames with precise parameters:

  • Identifier: Standard 11-bit or Extended 29-bit identifier (in hex or decimal).
  • Frame Type: Data frame or Remote Transmission Request (RTR).
  • Payload: Raw hex bytes separated by spaces (e.g. 01 02 03 AA FF).
  • Timing:
  • Single Shot: Transmit once upon click.
  • Periodic Transmission: Repeated transmission at specified interval in milliseconds (e.g. every 10 ms).

4. Frame Templates Library

Pre-loaded templates for instant testing:

  • CiA 402 Drive - Ready to Switch On (Controlword 0x0006)
  • CiA 402 Drive - Switch On (Controlword 0x0007)
  • CiA 402 Drive - Enable Operation (Controlword 0x000F)
  • CiA 402 Drive - Target Velocity (1000 RPM) (RPDO2 Velocity command)
  • SEVCON Gen4 - Throttle Request (RPDO1 Torque command)
  • J1939 - Address Claim Request (PGN Request)
  • Raw CAN Ping
