DIY Guide: Creating a PLC to HMI Keyence Cable for Old and New Series

Introduction

In the world of industrial automation, communication is paramount, and having the right cables to connect your devices is crucial. In this guide, we’ll walk you through the process of creating a cable to connect a PLC (Programmable Logic Controller) and an HMI (Human-Machine Interface) Keyence, specifically for old series like KV/KZ and newer models like KV-3000/KV7300. This cable is essential for transferring data between these devices, allowing you to program and monitor your automation systems. All you need are a few readily available components: an RJ-11 port (desktop phone jack) and a DB-9 female port.

Getting Started

Before we delve into the process, ensure that you have the required components on hand. Once you have the RJ-11 port and DB-9 female port, follow these steps to create your PLC to HMI Keyence cable:

• Prepare the RJ-11 Port: The RJ-11 port, commonly found on telephone jacks, is an essential part of this cable. Start by identifying the pins on the RJ-11 port; you will typically have six pins, numbered 1 through 6.

• Wiring Configuration for Old Series (KV/KZ): If you are working with an older series of Keyence devices like KV/KZ, you will need to connect pins 3 and 4 of the RJ-11 port to pins 2 (TXD) and 3 (RXD) of the DB-9 female port, respectively. This configuration allows for serial communication between the PLC and HMI.

• Wiring Configuration for Newer Models (KV-3000/KV7300): For newer models like KV-3000/KV7300, you may need to use the serial port on the HMI device. In this case, connect pins 3 and 4 of the RJ-11 port to pins 2 (TXD) and 3 (RXD) of the DB-9 female port, respectively. This setup allows you to establish a serial connection for programming and data transfer.

• Assemble the Cable: Once you have connected the appropriate pins, make sure the connections are secure and well-soldered. It’s important to ensure that there are no loose wires or short circuits.

• Testing: With your cable assembled, it’s time to test it. Connect the RJ-11 end to the PLC and the DB-9 female end to the HMI Keyence. Power up both devices and attempt to establish communication. If you encounter any issues, double-check your wiring and soldering. It’s also a good idea to verify that the communication settings on both devices match.

Troubleshooting and Further Assistance

Creating a custom cable can be a rewarding experience, but it’s not uncommon to encounter challenges along the way, especially if you’re working with different device models or configurations. If you find that your cable doesn’t establish a connection or if you have questions about creating other cables for different devices, don’t hesitate to seek assistance.

Additionally, the manufacturer’s documentation and support resources can provide valuable insights and solutions to specific connectivity issues.

Conclusion

In the world of industrial automation, having the right cables to connect your devices is essential. By following this DIY guide, you’ve learned how to create a custom cable to connect a PLC and HMI Keyence, whether you’re working with older series like KV/KZ or newer models like KV-3000/KV7300. With the right cable in hand, you’ll have the ability to program, monitor, and control your automation systems effectively.

Remember that troubleshooting and fine-tuning may be necessary, so don’t be discouraged if you encounter initial challenges. Seek assistance from the automation community and consult manufacturer resources to ensure a successful connection. Creating custom cables can be a valuable skill for any automation engineer, and it opens up a world of possibilities for optimizing your industrial processes.
