How can we connect to RSlogix for data logging in Excel directly over Ethernet without using RSlinx?
There are a few options. You can use a driver (C, C++, Python, etc.) or an OPC server (Kepware, Ignition, etc.).
Can you please some details if I want to implement it with a driver (C, C++, Python, etc.)?
Here’s some info on the Python library that will communicate over EtherNet/IP: https://pycomm3.readthedocs.io/en/latest/
I’ve worked with it in that past; you can send tag data into your python application and generate a spreadsheet from there.
There are others. You can find similar libraries for C/C++.
