本文通过对INTERBUS现场总线技术的研究,根据GD包装机的工艺特点,设计了以SIEMENSS7-400PLC为核心,加上INTERBUS现场总线的一套全新的PLC控制系统。3年多的运行结果表明:本文提出的系统设计方案是非常成功的,同时按照该方案进行的GDPLC的工程改造也很成功的。
Based on the research of INTERBUS fieldbus technology, this paper designs a brand new PLC control system with SIEMENS S7-400PLC as the core and INTERBUS fieldbus according to the technological characteristics of GD packaging machine. The results of more than three years of operation show that the system design proposed in this paper has been very successful and that the engineering of the GDPLC under this scheme has also been very successful.
