I have an aging Kuhnke 657 Programmable Logic Controller (PLC) integrated into my machine. We are planning to upgrade the Human-Machine Interface (HMI) to a C-More model. Can anyone provide information on the communication protocol used by this PLC? Your insights would be greatly appreciated!
For more information on the outdated controller, I recommend reaching out to Kuhnke directly to inquire about any available specification sheets or documentation. Best regards.
I have sent them an email regarding the programming software and am currently awaiting their response.
Is a card available? It appears that they offer support for several different types. For more details, visit: http://www.kuhnkeusa.com/bussystems.php
Everything operates on cards. The communication cable connects directly to the CPU card for seamless functionality.
Are you able to provide the part number and manufacturer of the HMI (Human-Machine Interface) in question? This information could simplify the process of determining its current communication protocols.
I’ve worked with the Kuhnke 657 before, and typically it uses the ASi (Actuator-Sensor Interface) or standard RS-232/RS-485 communication protocols. If you're planning to integrate it with a C-More HMI, you might need a converter or interface module depending on your specific communication setup. It could be worth double-checking the documentation for your PLC version to confirm the protocol details, but hopefully that gives you a solid starting point!

Answer: A1: The Kuhnke 657 PLC typically uses standard communication protocols such as Modbus, Profibus, or CANopen. However, it's essential to refer to the specific model documentation or contact the manufacturer for precise protocol details.
Answer: A2: Yes, the C-More HMI can interface with the Kuhnke 657 PLC, provided that the correct communication protocol is supported by both devices. Ensure that the C-More HMI supports the same protocol as the PLC, such as Modbus, for seamless integration.
Answer: A3: To ensure compatibility, follow these steps: 1. Identify the communication protocol used by the Kuhnke 657 PLC. 2. Verify that the C-More HMI supports this protocol. 3. Obtain the necessary communication cables and configure the HMI settings to match the PLC's communication parameters.
