4.2 ජාල වින්‍යාසය

The USR-DR301 requires network configuration to establish communication. This typically involves setting IP addresses, port numbers, and selecting the desired operating mode. Configuration is usually performed via dedicated software on a connected PC or through a web අතුරු මුහුණත.

Figure 4: Modbus RTU to Modbus TCP Configuration. This diagram shows how configuration software on a computer interacts with the USR-DR301 to enable Modbus RTU to Modbus TCP protocol conversion for communication with a PLC.

For detailed configuration steps, refer to the official USR product documentation or software user guide.

5. මෙහෙයුම් මාතයන්

The USR-DR301 supports several operating modes to accommodate various network communication requirements:

• TCP සේවාලාභියා: The converter initiates a TCP connection to a configured destination IP address and port. It will continuously attempt to reconnect if the connection fails.
• TCP සේවාදායකය: The converter monitors a specified port and waits for incoming TCP client connections. Data from the serial device is transmitted to all successfully connected clients.
• UDP Client: The converter communicates only with the target interface of a specified target IP address, ensuring data transmission accuracy.
• UDP Server: The converter automatically transmits received data to the last device it communicated with. This mode is suitable for scenarios where multiple network devices need to communicate with the DR301.
• HTTP Client: The converter supports transmitting serial data to a specified server using HTTP (GET/POST) requests.

This section provides basic troubleshooting steps for common issues. For more complex problems, refer to the official USR support resources.

• බල දර්ශකයක් නැත:
  • Verify the power supply is connected correctly and providing the specified DC 5-36V.
  • Check power cable connections and ensure the power source is active.
• ජාල සම්බන්ධතාවයක් නොමැත:
  • Ensure the Ethernet cable is securely connected to both the USR-DR301 and the network device (switch/router).
  • Check the network status indicators on the device and your network equipment.
  • Verify IP address settings and subnet mask in the device's configuration.
• No Serial Data Transmission:
  • Confirm the RS232 serial cable is correctly wired and connected to your serial device.
  • Check serial port settings (baud rate, data bits, parity, stop bits) in the converter's configuration to match the serial device.
  • Ensure the operating mode (TCP Client, TCP Server, etc.) is correctly configured for your application.
• Modbus Communication Issues:
  • Verify that the Modbus RTU and Modbus TCP settings are correctly configured, including slave IDs and register mappings.
  • Ensure the PLC or Modbus master is correctly configured to communicate with the converter.
