I work in a school so I work with PLCs with educational proposal. We are working with Siemens privative hardware/software and with some Arduino compatible shields .
I'm using PLCopen Editor to document ladder schemas and then I use plcLib library inf Arduino IDE to upload the schema. It is manual conversion but quite straightforward and, as far as now, it works fine. Any suggestion about this procedure?
I would also like to document the connection schema with an opensource application. Any suggestion?
