thank you very much for your advice, you confirm me in my search results. We will try this with Modbus and pymodbus library. Greetings!

Hi all, I have the following question. In a research Project we want to reach connectivity between (older) machines. For that, we want to make data from a PLC V430 available by using OPC UA. As V430 is not OPC UA-able, we want to connect the PLC to a RaPi and implement an OPC UA Server there. For that, can you please tell me, whether the communication between PLC V430 and RaPi is possible? What is the best way to communicate, Modbus tcp? Thank you very much for your Responses!
