Question

when is a touch screen preferred as an input device?​

Answer 1

Answer:

the PLC is programmed to control which screen is displayed it is much easier to guide the operator through the correct input sequence. Another benefit of a touch screen is the ability to do graphic indications. So we can animate the display to show status of motors, valves, flow paths etc The way you use your finger on a touch screen is very similar to how you use a computer mouse on a desktop computer. Technically speaking, a touch screen is an input/output device. Not only is it capable of accepting input, but it also displays the output from the computer
