软逻辑控制系统在uClinux上的实现

Realization of the SoftPLC Control System in the uClinux

本文首先给出IEC61131-3标准的软逻辑控制系统在uClinux上实现的原理;然后重点描述运行系统内存管理、网络通信;最后以AD7874数据采集程序来验证IEC61131-3标准的软逻辑控制系统在uClinux上的实现。

This paper introduces the theory of realization of the softPLC control system based on IEC 61131-3 standard in the uClinux system; Then place emphasis on system memory management, network communication; At the last, examine the implement in uClinux of IEC 61131-3 standard based softPLC control system by running AD7874 data acquisition programs on the system.
