摘　　要：提出了一种基于uC/OS-Ⅱ的编译型PLC运行系统的设计方法,并对运行系统中任务间调度、内存分配和任务间的通信原理进行了分析讨论。This paper introduced the principle of compiled and interpreted PLC and proposed a design approach for an uC/OS-II based compiled PLC system. This paper further discussed its task scheduling, memory distribution and task communications. Results show that it is a better approach for a PLC which has complicated control functionality and data processing program.
