This application note describes how the Mikom MX2H series PLC is used to control a multicolor printing machine via CAN bus, covering system architecture…
The document presents a solution that uses Mikom MX2H series PLCs with CAN bus communication to manage a multicolor printing machine. The main station uses an MX2H‑3232M‑CAN PLC for logic control and touchscreen communication, while MX1H‑1616‑CAN PLCs serve as remote I/O stations.
Key features include extensive expansion modules, multiple communication interfaces (RS‑232, RS‑485, CAN), fast instruction processing, Ethernet remote maintenance, and specialized high‑speed commands for precise ink and water control, plate adjustment, and system responsiveness. This manual is written in Chinese.
