Using a raspberry pi and NVLs to log variables outside of Codesys

    Hi,

    My PLC/controller doesn't support OPC UA, so my current plan to create a ringbuffer/circular logger is to connect a raspberry pi to it, use the Network Variable List receiver and sender and raspberry pi codesys runtime to get the variables to the raspberry pi, after which I will use the pi which DOES support OPC UA to get the variables to a python program which logs the desired variables for a certain amount of time for me, would this work? I don't want to spend 50+ euros + licencing fees for a solution that might not work.
