Hi,
I am designing measurement devices and i intend to use Simatic S7-1200 as PLC for my new device. The problem is, my background is nothing close the electric and I am having quite a lot troubles when it comes to select components, I do not know how can I select components that are compatible with the PLC i am going to use.
Pressure sensor, humidity sensor shall be selected and which parameters I should be careful about?
I read somewhere 24VDC supply voltage is needed. Is it needed even the device has digital output or is it for analog output only?
How do I make sure about the communication interface? For some devices it says I2C, is that compatible with S7-1200? or do i need a special communication module for each component? Then it will be super expensive.
I would appreciate any answer.
