摘要
介绍了软PLC技术的发展状况、相关的概念和组成结构,并且把它和传统的硬PLC做了一些控制方案等方面的比较。提出了基于开放式数控系统上的软PLC系统,并对本系统中的控制方案、开发系统和运行系统做了较为详尽的介绍。软PLC系统在开放式数控系统RTLinux中应用稳定,并节约了成本。
State-of-the-art of the Soft-PLC technology is addressed, in which the related concepts and the architectures are mentioned . Moreover, the control schemes between Soft-PLC and the traditional Hard-PLC are compared. Henceforth,a Soft-PLC system for the Realtime-Linux based on CNC system is presented, and its control scheme, development system and running system are explained in detail. The application of the Soft-PLC technology in Open Architecture CNC System is relatively stable , and saves the cost .
