The Design and Implementation of Virtual Machine System in Embedded SoftPLC System

摘要

Embedded Soft PLC is a new high technology in industrial control area, which gets over the defects of traditional PLC and has come to general attention in this area. Virtual machine system is the kernel of embedded Soft PLC system. This article narrates carefully the design and implementation of virtual machine system with the example of an embedded Soft PLC system product-ESDDC. The virtual machine designed in this paper will put forward a new plan of Soft PLC programming, and at the same time it also provides a new thinking of software design for software developers.
