PLC Scan Time Explained: How Cycle Time Affects Real-Time Machine Control
PLC scan time explained: the four-stage scan cycle, scan vs response time, jitter, and how to measure and optimise cycle time for reliable real-time machine control.
ESP32 as an Industrial PLC: Building Open-Source Automation Controllers with Ladder Logic and Modbus in 2026
Key Takeaway: The ESP32 microcontroller, costing under $10, can replace traditional PLCs costing $500+ for many industrial automation tasks by running open-source ladder logic runtimes, Modbus RTU/TCP communication, and MQTT-based…
