Absolutely, I can help with that! To set up communication between Arduino and Siemens Logo using Modbus TCP/IP, you’ll first need a Modbus library for Arduino (like ModbusMaster or ModbusTCP). On the Siemens Logo side, you’ll configure it as a Modbus server. There are some great tutorials on sites like Instructables or GitHub that walk you through similar setups step by step.

I doubt you will find a complete guide for LOGO!, it's an industrial device generally used by professionals not hobbyists.

However, the Arduino side is probably easier; I am sure there are examples for Arduino Modbus TCP master/slave, probably not a "complete tutorial".

I think you will need to learn some basics to put it together. I would start with a two Arduinos with Ethernet shield and practice setting up communications between those two devices.

Also, Siemens have a web forum where you can ask about specifics of LOGO!. https://support.industry.siemens.com/forum/gb/en?block=0&tab=1#!?SortOrder=lastpost_desc
