Infrared control with s7-1200

Hi everyone,

I want  to control an AC by remote control with infrared using s7-1200. Someone know what type of hardware i need and how i can do that by plc?

Thanks in advance.

Hello,

in this case you need use 3-rd party controller with Infrared capability like Arduino. In this case use of S7 is not expected. In case you need use S7 PLC, then you can control infrared with 3-rd party controller and exchange data with S7-1200 via suitable comm channel - serial or ETH.

Update: you can pls better describe what infrared control you need to do, then we can maybe give better help.

Hi Duris,

I know i can do that with arduino or raspberry, but the idea is not to use this type of controllers.

In last instance i will try using serial port from PC and convert to IR. About this option, i still searching how to do.

With infrared control i want to control my AC, the same way as with the AC remote comand.

Hello,

hope you understand how IR remote control works. Theoretically via RS232 it can be possible without problems but you need to know one important thing - how is signal defined due button pushed on control. It's generally some defined signal with length and also possible repeat of different length of signal. This can be prepared via f.ex. RS232 one control signal but you need to be very precise with that, I don't know what error value has that IR reader. You need make tests. But how you want read that signals from AC control to know that? In this case you need that Arduino f.ex. to record that each key signal and then you can copy it to your controller signal.

Update: Huggy have good idea, in this case you don't need do that but I expect you didn't think what you really need to do with that control adaptation to your PLC
