摘要
为有效解决传统PLC存在的缺陷,以及国内PLC市场长期被国外厂商垄断,进而导致PLC供货周期漫长、价格昂贵的问题,经深入研究,设计了一种基于CoDeSys的嵌入式软PLC系统。该系统采用NXP的MIMXRT1176CVM8A微处理器为主控芯片,实时操作系统采用FreeRTOS,同时搭载CoDeSys实时运行系统,以此实现符合IEC 61131-3标准的软PLC系统。经严格试验验证,此设计的嵌入式软PLC系统具有显著的开放性、通用性,在工业控制领域展现出较好的应用价值。
In order to effectively address the deficiencies existing in traditional PLCs,and the issue that the domestic PLC market has long been monopolized by foreign manufacturers,which consequently leads to a long supply cycle and high prices of PLCs,an in-depth study has been carried out and an embedded soft PLC system based on CoDeSys is designed.This system uses NXP’s MIMXRT1176CVM8A microprocessor as the main control chip,adopts FreeRTOS as the real-time operating system,and is equipped with the CoDeSys real-time running system simultaneously,so as to realize a soft PLC system that complies with the IEC 61131-3 standard.Through strict experimental verification,the designed embedded soft PLC system has remarkable openness and versatility,and demonstrates good application value in the field of industrial control.
