What happens when voltage is applied to the terminal Local:1:I:Data.0 of an active high PLC input module?

When voltage is applied to the terminal Local:1:I:Data.0 of an active high PLC input module, it results in the input being considered "on" or "true." This is because active high inputs are energized when these voltages are detected, leading the PLC to register the input state accordingly.

In this context, if an XIO (Examine If Open) instruction is used with the same address, it would evaluate the state of that input. Since the input is now detected as true due to the applied voltage, the XIO instruction looks for the condition of the input being "off" (or false). Because the input is indeed active (on or true), the XIO instruction will evaluate to false. Thus, the correct answer is that the XIO instruction with the same address gives a false result.

This understanding of how active high inputs function is crucial for interpreting PLC logic and addressing programming instructions efficiently.
