PG2 bar graph (Symbol Factory bar) slow.
I'm using few Symbol Factory bar to show bar graph for process variables in PG2 graphics in 5.1FP4revD RU2.
The graphic contains several other graphical elements too. Opening the graphic updates all the values immediately except the bar graph. It might take 10 seconds to 5 minutes before bar shows filled.
The same OPC variable that is going to bar graph updates immediately if linked to another display element.
Diagnostic of graphics show all OPC value were received within one second and there was no error. Looks like there is some bug in Symbol factory bar.
I tried one graphic with just one Symbol Factory Bar with same results.
Anyone observed this?
PG2 graphics wok properly the Render tier should be 2 where as in your case its 0 please look into this.
Regarding the bar graph i have some doubts.
1.whether you are using common alarm list properties or global alarm properties or local block alarm properties to show the alarm color as the limit reaches in bar?
Yes, It happens few times.
I have faced it too, with any graphic display property .
The Most common reason for this :
You must be using STRING type variable to make your Bar fill in.
Try avoiding using it and make a small code, that When your String becomes equal to your Required string, then its TRUE output generates a 1 bit, or it enables a Counter, of "int " type, and then finally you use it to fill your bar.
It may not be accurate, as I am not aware of your code & application, but main point is avoid using String data type varaible for such graphics .
