In ControlLogix, what does I/O stand for?

In ControlLogix, I/O stands for Input/Output. This terminology is fundamental to understanding how automation systems like ControlLogix operate. Input refers to signals or data received from various sensors and devices that feed information to the PLC. This could include data from switches, temperature sensors, or other monitoring equipment. Output refers to the control signals sent from the PLC to actuators or other devices, such as motors, valves, or lights, to perform a specific action based on the processed input data. The Input/Output architecture enables PLCs to interact with the physical world, bridging the gap between digital processing and analog events. Understanding I/O is crucial for programming and troubleshooting in any ControlLogix application.
