NodeRed and Siemens S7 with Profibus to LAN adapter

[Babar]

Hello,

I want to get data from a Siemens S7 PLC and i have a profibus->Ethernet adpter. Does anybody know, how to do so? See the architecture and our intention what to do.

Regards

For me the main question is how does the Profinet -> Ethernet adapter provide the data. Please check the description of this device to see how the interface looks like and works.

For general information how to communicate with Node-Red and 3rd party controllers see this thread.
