In a PLC system, when are outputs generally energized?

In a PLC system, outputs are generally energized when the Run mode is activated. In this mode, the PLC executes the logic as defined in its program, responding to inputs and manipulating outputs accordingly. The Run mode is crucial for the operation of the PLC, as it actively controls machinery or processes based on the programmed rules and conditions.

While in Program mode, the PLC does not execute the logic. This mode is primarily for making changes and defining the logic of the control system without causing any actual outputs to be activated. Similarly, during the editing phase of a project, any changes made to the logic will not affect the execution of commands since the program is being modified rather than run. The debugging stage is focused on testing and troubleshooting the logic, often in a controlled manner where outputs may not be energized to prevent unintended actions.

Thus, the only situation in which the outputs are energized and the logic is actively controlling processes is during the Run mode, making this the correct answer.
