Communication Setup Method for Prolet Controller and Yuanxin Inverter YX3000

In modern industrial automation systems, the communication setup between controllers and inverters is crucial for achieving efficient and stable operation. This article will combine the “Prolet Air Compressor Controller and Inverter Communication Setup Manual” and the “Yuanxin Inverter YX3000 Manual” to provide a comprehensive guide on setting up the communication between the Prolet controller and the Yuanxin Inverter YX3000.

1. Communication Protocol Description of Prolet Controller

The Prolet controller adopts a communication protocol that is compatible with industry standards, such as MODBUS RTU. This protocol ensures reliable data transmission between the controller and various devices, including inverters. The key features of the Prolet controller’s communication protocol include:

• Baud Rate: Typically set at 9600 bps, which is a common baud rate for industrial communication.
• Parity: No parity bit is used to simplify the communication process and reduce errors.
• Data Bits: 8 data bits are used to ensure sufficient data transmission capacity.
• Stop Bits: 1 stop bit is employed to mark the end of each data frame.

To establish communication with the Yuanxin Inverter YX3000, the Prolet controller needs to be configured with the appropriate communication parameters, such as the address of the inverter, baud rate, and data format.

2. Communication Protocol Description of Yuanxin Inverter YX3000

The Yuanxin Inverter YX3000 also supports the MODBUS RTU communication protocol, making it compatible with the Prolet controller. The YX3000 offers a wide range of communication settings to meet different application requirements:

• Communication Interface: Equipped with standard RS485 communication interfaces, the YX3000 can be easily connected to the Prolet controller using shielded twisted-pair cables.
• Communication Address: Users can set a unique address for each inverter on the network to facilitate multi-inverter communication.
• Baud Rate and Data Format: The YX3000 supports various baud rates (e.g., 1200, 2400, 4800, 9600, 19200, 38400 bps) and data formats (e.g., 8N1, 8N2).

To establish communication with the Prolet controller, the YX3000 needs to be configured with the same baud rate, data format, and communication address as the controller.

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.
