【Abstract】The hardware and software design platform of embedded soft PLC is presented. Embedded soft PLC system for industrial control is
developed by the techniques of ladder diagram, hardware interface mapping and modular design. This system is composed of development system
and operating system. The development system translates the programs based on graphics language into target code, and the operating system loads
the target code and executes command based on the code to control the system.
【Key words】embedded soft PLC; ladder diagram; mapping technology
