Integration between PLC Keyence KV8000 (EtherNet/IP scanner and adapter) to Raspberry PI 5

[itbdelaboprogramming]

Hello OpENer community,

I am currently working on an industrial integration project and would like to ask for guidance regarding the use of OpENer in a mixed PLC–embedded system setup.

System Overview:

• PLC: Keyence KV-8000 (supports EtherNet/IP Scanner and Adapter modes)
• Edge Device: Raspberry Pi 5 (Linux, Debian environment)
• Goal: Establish cyclic I/O communication and/or explicit messaging between KV-8000 and Raspberry Pi

Objective:
I would like to use OpENer on the Raspberry Pi as an EtherNet/IP Adapter, allowing the KV-8000 (Scanner) to:

1. Read sensor data processed on the Raspberry Pi
2. Send control commands back to the Raspberry Pi

Current Understanding:

• OpENer is designed as an EtherNet/IP Adapter stack, which seems suitable for this use case
• Raspberry Pi 5 should be compatible with the POSIX port
• KV-8000 can act as a Scanner and should be able to establish I/O connections

Questions:

1. Has anyone successfully used OpENer on a Raspberry Pi (especially newer models like Pi 5) in a real industrial setup?
2. Are there any known limitations when interfacing with Keyence PLCs (KV series) via EtherNet/IP?
3. For cyclic I/O communication:
   • What is the recommended approach to define Assembly Objects for stable real-time data exchange?
4. Is OpENer sufficient for moderate real-time requirements (e.g., ~10–50 ms cycle time), or would additional tuning be required?
5. Are there examples or best practices for integrating OpENer with external applications (e.g., Python or C++ processes handling sensor data)?

Additional Context:
This project is related to a conveyor volume scanning system, where the Raspberry Pi processes sensor data (LiDAR / vision), and the PLC handles control logic.

Any guidance, references, or example implementations would be greatly appreciated.

Thank you for your work on OpENer and for supporting the community.
