Hello everyone, I want to acquire the values of variables from a Rexroth L40 PLC. They are simple variables like button 1 and LED 1.
I can connect using IndraLogic to see how the variables are activated, but I can't find a way to retrieve those values using OPC UA, Modbus, etc. My goal is to develop a Python script that allows me to send variable information in real time to a database.
