摘要
本系统利用组态软件WINCC良好的人机界面和S7-PLCSIM的多种视图对象,并结合西门子STEP 7便利的编程环境,依托MPI协议实现了模拟PLC和组态软件之间的数据传输。利用WINCC组态油气集输站水箱控制系统装置的组态画面并通过对实际过程控制实验系统的模型分析在WINCC中通过脚本实现系统数学模型的建立,实现无硬件化的水箱控制虚拟系统的模拟。
The system using configuration software WINCC good interface and several views of S7-PLCSIM objects, and Siemens STEP 7 programming environment, relying on the MPI protocol, simulated data transfer between PLC and configuration software. Using WINCC configuration device water tank system in oil and gas gathering system configuration screen and through to the actual model analysis of process control systems through scripting in the WINCC system establishment of mathematical model to achieve a virtual water tank system simulation of hardware.
