PLC (Programmable Logic Controller) and HMI (Human Machine Interface) programming are integral components of industrial automation. PLCs control machinery and processes, while HMIs provide a user-friendly interface for operators to monitor and interact with these systems.
PLC Programming
PLC programming involves creating logic to control inputs and outputs of industrial equipment. It is typically done using ladder logic, function block diagrams, or structured text. The PLC executes this logic to automate tasks such as starting/stopping machines, managing sensors, and controlling actuators.
Example of Ladder Logic for a Simple Process
