When voltage is applied to the terminal Local:1:I:Data.1 of a PLC input module, what is the result with an XIC instruction?

When voltage is applied to the terminal Local:1:I:Data.1 of a PLC input module, the result with an XIC (Examine If Closed) instruction is true. This is because the XIC instruction is designed to evaluate the state of an input. When an input is energized, which is indicated by the presence of voltage at the specific input terminal, the XIC instruction assesses this condition and returns a true logical state.

In the context of PLC programming, the XIC instruction will pass the signal through to the output or subsequent logic instructions, confirming that the input is active. This behavior is fundamental to how PLCs operate and allows for the automation of processes based on real-time input conditions. The association of true with the energized state is a key principle in ladder logic programming, making it essential for students to understand this relationship when designing or troubleshooting control systems.
