Clear answers to common questions about industrial automation, PLCs, SCADA, DCS and HMI systems.
Industrial automation uses control systems, sensors, software and machines to monitor or operate industrial processes with less manual intervention. PLCs, SCADA, DCS and HMIs are common parts of an automated system.
A PLC controls machines and discrete processes, SCADA supervises and visualizes equipment across a site, and a DCS coordinates continuous process control across a plant. They can work together in one automation system.
Current areas of development include Industrial IoT, edge computing, AI-assisted analytics, digital twins, collaborative robotics and stronger industrial cybersecurity. Their value depends on the process and the system they support.
Common IEC 61131-3 languages include Ladder Diagram, Function Block Diagram, Structured Text and Sequential Function Chart. Which one you use depends on the controller, project and maintenance requirements.
Start with electrical and control-system basics, then practise PLC logic, HMI screens, alarms and SCADA communication using simulation or supervised hardware. Explore Infercon Automation training courses.
An HMI gives operators a visual interface to monitor equipment, view alarms and trends, enter setpoints, and issue permitted commands to the control system.
