Lingkong LK3U/ZK3U PLC with Ethernet, Mitsubishi FX3U-compatible

by

The Lingkong LK3U/ZK3U PLC industrial control board is a highly compatible and versatile controller, designed to work seamlessly with Mitsubishi FX3U PLC. It offers enhanced Ethernet functionality, allowing for efficient and reliable industrial automation. Below is a detailed explanation of its key features:

Key Features of the Lingkong LK3U/ZK3U PLC:

  1. Ethernet Functionality:
    • Supports 8 independent ports, of which 5 ports (0-4) are enabled by default, all using MELSOFT connection mode.
    • The 5th port is dedicated to the MODBUS TCP server function.
    • The 6th port supports SNTP when enabled via programming software, making it perfect for time-synchronization applications.
    • The 7th port is a fixed port that supports MELSOFT connection mode.
  2. GX Works2 Integration:
    • The board supports GX Works2 programming software, enabling you to search and detect FXCPU on the network. This includes the automatic detection of FX3U PLC models and their corresponding IP addresses.
    • However, the latest version of the control board only allows the use of dedicated Ethernet parameter software to download Ethernet parameters. These cannot be set through GX Works2, and the Ethernet diagnostic function within GX Works2 is not supported.
  3. Connection Support: The board supports a wide range of connection types to maximize its functionality in different industrial applications:
    • MELSOFT connection
    • MODBUS S (MODBUS TCP/UDP server)
    • SNTP connection (for network time synchronization)
    • MODBUS C (MODBUS TCP/UDP client, with support for up to 247 slaves in UDP mode and 7 slave stations in TCP mode).

Setting Up Ethernet Parameters

To configure the Ethernet settings:

  • Download Ethernet parameters via the dedicated Ethernet parameter software.
  • After setting the parameters, a power cycle is required for the new configurations to take effect.

Conclusion

The Lingkong LK3U/ZK3U PLC control board provides robust Ethernet connectivity and supports various protocols that make it highly versatile for industrial control systems, especially in environments that require integration with Mitsubishi FX3U PLCs. While it offers extensive functionality, it’s important to note the limitations when using GX Works2 for Ethernet parameter settings.
