I have some questions to ask about connecting a sensor to a PLC. I have decided to use Siemens LOGO for this application.
1. Are inputs usually in the form of electrical current? Or does it depends on the type of PLCs?maybe voltage?
2. What does it mean by analog value processing is in the 12V DC and 24V DC? Is it the input signal to the PLC?
3. How does the PLC recognizes that a input is a HIGH or a LOW? Is it something to do with the programming?
4. Does it matter if we choose the type of power supply for the PLC? It depends on the availability of the power supply,is it?
Thank you!
