This is an ePLC programming manual that provides detailed information about ePLC overview, resources, soft elements and instructions.
The document introduces the ePLC embedded controller family, covering hardware architecture, configurable I/O, and supported communication interfaces. It details the soft PLC kernel, IEC 61131‑3 compliant instruction set, and programming tools such as ControlStudio.
Programming guidance includes a complete list of relays, data registers, special function blocks, and example ladder‑logic programs for common tasks like motor start‑stop, timing, counting, and PID/fuzzy control. This manual is written in Chinese.
