Good morning,
use codesys with a raspberry card that controls two plc controllino.
Now I wanted to be able to control the heat pump with an infrared led with another raspberry card placed in the house.
Choosing the settings is in codesys but how can i send it to the raspberry card?
That is, what method of communication should I use and then how do I send the command?
Give me a line to follow?
Thank you, Alberto
