Under which condition will the Y output be energized?

In programmable logic controller (PLC) systems, the output Y is energized based on the states of the inputs X1, X2, and X3. Typically, an output will be activated when specific conditions or combinations of the inputs are met according to the ladder logic or function block diagram programmed into the controller.

For the chosen condition, where X1 is true, X2 is false, and X3 is true, this particular scenario indicates that there is a valid condition that allows Y to be energized. Often, a logic statement will determine the activation of outputs based on a logical combination of input states, which can include AND, OR, and NOT operations.

By analyzing the other conditions given:

• When X1 and X2 are true and X3 is false, this typically does not meet the energizing criteria based on the programmed logic.

• If both X1 and X2 are false with X3 being true, it might not provide sufficient input signals depending on the overall logic structure.

• Lastly, for the condition where X1 is false, X2 is true, and X3 is false, this likely does not meet the necessary input requirements for activating Y.

Thus, the condition where X1 is true and X3 is also true
