RealTime Simulation
Posted: Fri May 19, 2006 3:34 am
Hi there,
I have installed DPlotJr and testing it in my program for real time simulation of an industrial process. I admit it is at least 4 times faster than what I was using before. I will get a distributable licence once I solve couple of issues. The important one being is this: My program does a calculation minute by minute and at some point it does an optimisation. To do the optimisation it needs a sample analysis from the process. Timing of the sample taking for analysis is important (let's say 2:00 pm).But the analysis results received roughly 20 min later. So we are at 2:20 in real time. Now I need to go back in time and do my optimisation at the time sample was taken (2:00pm). Then recalculate the process and show it in my XYXY plot (all takes less than a minute) and continue in real time (2:20 pm).When I all do in DPlot the graph becomes messy cos it draws continues lines (like scribling).What I would like to do is delete the last 20 min of data and redraw it from 2:00 pm with the optimised values. That way I will get a continues line. Is this possible? Or is there a way to get around this? I am using VB 6.0.
Thanks in advance,
Hudai Kara
