Hi,

I saw this very interesting video on youtube where an arduino interfaces with an Siemens S7-1200.


Does anybody have an idea how he makes the interface between the arduino and the PLC ?

Thanks,
Koen

It looks like is using serial or modbus rtu?

Im currently trying to get a arduino ethernet to be a modbus tcp slave for the plc. So i can connect all sorts of sensor to it, and do some datalogging on the plc.
