Hi everyone. I have a project that connect S7-1200 with Arduino via MODUS RS485. There are lack of documents and guidelines about this problem on the internet. Hope you guys can help me, thank you very much.
There’s some reading in… HERE
Hi,
Have you read the manual for this device?
Especially chapter 10.
I'm not an expert in this area, but it looks like the S7-1200's protocol is profibus(PROFINET). I don't know if it works with the modbus protocol.
Maybe you need gateway between modbus and profbus.
