“I intend to make an automated system for my home with a combination of PLC SIEMENS and ARDUINO. I think we can combine their own strengths to make the automation system running in stability, optimization and acceptable price. So I took times to consult, study and perform some below experiments before applying them to my home.
Toogle a lamp 220 VAC from touch button of Arduino via Profibus-DP.
Display the PT100 temperature value on the 64x64 led matrix via Profibus-DP”
