基于可编程控制器(PLC)与操作员面板(OP)创新结合的平台,提供了一个安全可靠、实时操作和高效快捷的测量和控制系统,不仅扩展了PLC的功能,使其具有图形化、交互式工作界面的独立系统,而且大大减少了操作台上开关、按钮、仪表等的使用数量,使得编程和操作工作非常轻松舒适。提出了利用西门子S7-300系列PLC、OP构成的综合测控系统设计方案。设计了测控系统的组成、PLC和OP硬件结构及软件框图、操作面板组态画面以及主要监测功能,在实际的应用中提高了自动化测试程度及测试的数据精度和准确性,取得了良好的应用效果。
Based on an innovative combination of programmable logic controller (PLC) and Operator Panel (OP), it provides a safe, reliable, real-time operation and efficient and efficient measurement and control system that not only extends PLC functionality to provide a graphical, Interactive work interface independent system, but also greatly reduced the number of switches, buttons, gauges, etc. on the console, making programming and operation very easy and comfortable. Proposed the use of Siemens S7-300 series PLC, OP constitute a comprehensive measurement and control system design. The composition of the measurement and control system, the hardware structure and software block diagram of PLC and OP, the configuration screen of the operation panel and the main monitoring functions are designed. The accuracy and accuracy of the automatic test and the test data are improved in the practical application. effect.
