I am starting a new project, this project is about industrial automation.
My main objective is to use a raspberry in order to communicate with some PLC (Siemens, Rockwell and Schneider).
Through this communication, I would like to historized some data in a SQL database which could be embedded on the rpi.
I'm aware that some lib exist to read PLC data, like libnodave but theirs lib are usable for unique target (Siemens in this case) but the main idea is to be able to connect to all PLC.
What do you think about this?
Share every idea you get ! XP
