MULTIFUNCTIONAL XY CURVE DRAWING OF FUNCTION TREND CONTROL BASED ON WINCC
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
Using C script language to process data and control variables of WINCC function trend control, a multi-function XY curve drawing based on WINCC function trend control is implemented. This method creates multiple custom array variables in the WINCC global C script, stores the collected data in the corresponding array variables, uses C script language to process the stored data, and then draws the function trend control according to the relationship between variables, and completes the rendering of the multi-function XY curve. The drawn curve overcomes problems such as missing, overlapping, trailing, and unmaintainable curves caused by time changes or switching of the operation screen in the WINCC function trend control. Finally, data acquisition is triggered according to whether time or data changes, so as to ensure the real-time data acquisition.
