What will happen when PB1 is pressed and held in the context of LAMP L2?

When PB1 is pressed and held, LAMP L2 will be ON. This is because a push button (PB1) typically functions as an input that can control outputs such as LAMP L2. When the button is engaged, it sends a signal to the controller indicating that it should activate the associated output, which in this case is LAMP L2.

Therefore, as long as PB1 is held down, the controller recognizes that it should keep LAMP L2 in an ON state. This is a common behavior in programmable logic control systems, where the state of an output is directly influenced by the input signals. The design of the system allows for the continuous activation of LAMP L2 while the button is pressed, illustrating the direct relationship between input control and output response in programming logic.
