3. Detailed Parameters Required for Communication Between Prolet Controller and YX3000

To set up communication between the Prolet controller and the Yuanxin Inverter YX3000, users need to configure the following detailed parameters on both devices:

  • Communication Address:
    • Prolet Controller: Set the communication address of the YX3000 in the controller’s communication parameters. This address should be unique on the network.
    • YX3000 Inverter: Set the communication address of the inverter to match the address configured in the controller.
  • Baud Rate:
    • Prolet Controller: Set the baud rate to 9600 bps (or other compatible baud rates) in the controller’s communication parameters.
    • YX3000 Inverter: Set the baud rate to 9600 bps (or the same baud rate as the controller) in the inverter’s communication parameters.
  • Data Format:
    • Prolet Controller: Set the data format to 8N1 (8 data bits, no parity, 1 stop bit) in the controller’s communication parameters.
    • YX3000 Inverter: Set the data format to 8N1 (or the same data format as the controller) in the inverter’s communication parameters.
  • Additional Parameters:
    • Prolet Controller: Depending on the specific model and functionality, the controller may require additional communication-related parameters to be configured, such as communication timeout settings, retry intervals, etc.
    • YX3000 Inverter: Similarly, the inverter may also have additional communication parameters that need to be configured, such as communication port settings, communication protocol selection, etc.

After configuring the above parameters, users can test the communication between the Prolet controller and the Yuanxin Inverter YX3000 by sending test commands from the controller and observing the responses from the inverter. If the communication is successful, users can proceed with the integration of the two devices into their industrial automation system.
