In this guide, we will show you how to create your own HMI connecting cables for different PLC brands, saving you time and money compared to purchasing pre-made cables. We will cover connections to PLCs such as Keyence KV/KZ CPU, Mitsubishi FXN-Series, Omron, and Panasonic.

Why Make Your Own HMI Connecting Cables?

Creating your own HMI connecting cables has several advantages. It allows you to:

1. Save Costs: Purchasing pre-made cables can be expensive, especially if you need different cables for various PLC brands.
2. Customization: DIY cables can be tailored to your specific requirements and cable lengths.
3. Quick Repairs: If a cable malfunctions, you can easily replace or repair it with the necessary materials at hand.

Materials Required:

To make your HMI connecting cables, you’ll need the following materials:

1. Appropriate connectors for the PLC brand you’re working with (e.g., Keyence, Mitsubishi, Omron, Panasonic).
2. A cable with the desired length (usually a shielded twisted pair cable).
3. Soldering iron and soldering wire.
4. Wire strippers and cutters.
5. Heat shrink tubing.
6. Electrical tape.
7. Pinout diagrams for the specific PLC models you are connecting.

Step-by-Step Guide:

Follow these steps to create your own HMI connecting cables for different PLC brands:

1. Gather Materials:
   • Ensure you have all the required materials and pinout diagrams for the PLC models you intend to connect.
2. Prepare the Cable:
   • Cut the cable to the desired length, keeping in mind the distance between your HMI and the PLC.
   • Strip approximately 1-2 inches of insulation from both ends of the cable.
3. Identify Pinout:
   • Refer to the pinout diagrams to identify which wires need to be connected to each pin on the PLC and HMI connectors.
4. Solder the Connections:
   • Connect the stripped wires to the appropriate pins on the PLC and HMI connectors.
   • Use a soldering iron and soldering wire to secure the connections.
   • Ensure proper insulation and prevent any crossed or shorted connections.
5. Insulate and Secure:
   • Gently slip heat shrink tubing over the soldered connections.
   • Heat the tubing to shrink it, providing insulation and protection.
   • Use electrical tape to secure and bundle the cables neatly.
6. Test the Cable:
   • Before using the cable, test it to ensure it works correctly and reliably.
7. Connect to the PLC:
   • Plug one end of the cable into the PLC’s designated communication port.
8. Software Configuration:
   • Install any necessary software or drivers to establish communication between your HMI and the PLC.

Conclusion:

Creating your own HMI connecting cables is a cost-effective and practical solution for connecting Keyence VT3-W4 HMIs to various PLC brands. By following the steps outlined in this guide and referring to the pinout diagrams specific to your PLC models, you can have reliable and customized cables that meet your industrial automation needs.
