What does the term 'output' refer to in the context of PLC instructions?

In the context of PLC (Programmable Logic Controller) instructions, the term 'output' specifically refers to the signals sent to actuators or displays. Outputs are critical components of PLC operations, as they represent the actions that the system takes based on the executed logic. For instance, when a PLC processes certain inputs and follows the programmed logic, it generates outputs that control devices such as motors, lights, or alarms. These outputs effectively communicate the results of the PLC's decision-making process to the external environment, enabling automated processes to be executed in industrial settings. Understanding this concept is fundamental as it highlights the PLC's role in controlling machinery and production processes.
