Outputs from a PLC control physical devices in a plant, such as pumps and valves.
Discrete inputs indicate states, like whether a tank level is high or low, while analog inputs provide continuous measurements, such as current height.
Adjusting the output can change the flow rate, e.g., turning a pump on is a discrete output command.

Output commands enable precise control of processes, such as:
- Turning on a pump to drain a tank.
- Opening an inlet valve to allow fluid into the tank.
- Managing outlet valves for liquid ejection from the tank.
Fine adjustments can be made through analog outputs to modify flow rates more precisely.

Discrete outputs only have two states (on/off), suitable for simple commands.
Analog outputs control devices at varying levels rather than just binary states.
Outputs may be connected via a bus network, transmitting commands efficiently across a plant.

Wireless networks can be utilized for outputs, providing flexibility without needing complex wiring.
Examples include wireless commands to valves through the industrial internet of things (IIoT).
Wireless telemetry enhances operations by reducing installation costs, especially in large facilities.

Vendor-specific concepts often lead to the development of standards, like wireless HART and ISA 100.
LoRa (Long Range output standard) is emerging as a widely adopted protocol in both heavy industry and IoT applications.

The HMI provides digital output information to operators, facilitating real-time control and monitoring.
A data historian logs and trends information over time, crucial for long-term data analysis and operational improvements.
