摘要
以SIEMENS公司S7-200 PLC指令集为背景,详细研究PLC运行原理,给出PLC编程语言的解释方法,在STM32系统上用C语言实现对PLC指令的解释和执行。将经过编码后的PLC程序固化在STM32的内部RAM中,再运用STM32处理器处理其逻辑关系,实现PLC的基本功能。
This dissertation, firstly interpretive method in detail based on the implementation of instruction set of SIEMENS S7-200 series, and then carries out the interpretation and execution ofPLC STM32 system with C Language.After the PLC program encoded solidified in the STM32 internal RAM, then use the STM32 processor handles its logical relations and realize the basic functions of the PLC.
