摘要
为了解决在无PLC硬件条件下的教学及远程资源共享问题,提出了一种面向全虚拟PLC的远程试验系统。该系统由PLC编程仿真软件、组态软件、中间件等构成,可灵活模拟具有上下位机的实际PLC系统;通过Web发布将平台与各个终端机相联,可实现资源的远程共享。该试验体系为PLC教学提供了完整的本机调试、上下位机控制及网络连接的现代试验平台,是一种先进的PLC试验教学系统。
In order to implement the teaching and remote resources sharing under condition without PLC hardware; the full virtual PLC remote experimental system is proposed. The system consists of the PLC programming simulation software, configuration software, and middleware, and it can simulate the real PLC possesses host computer and slave computer flexibly, and the platform and various terminals are connected via Web publishing for realizing remote sharing of resource. The experimental architecture provides complete modern experimental platform of native machine, host and slave computer control as well as network connection for PLC teaching, it is an advanced PLC experimental and teaching system.
