This article uses Schneider Electric’s EcoStruxure Machine Expert platform to describe PLC-based design of a semi-automatic liquid mixing application. Operating two solenoid valves (for two liquids) and an agitator motor using discrete pushbutton commands takes front stage in the application. It guarantees correct and safe filling by means of interlock systems. Why Liquid Mixing Needs … Continue reading Step-by-Step PLC Ladder Logic for Automatic Liquid Mixing Process with Interlocks
