Hi! My name is Bruno! I have several points in my system with a 00:00:00.2 scan frequency (it's necessary for our process). But when these points are shown in a display, their update rate are too slow, blowing out the operator sensibility on controling the process variable. Is there a way to increase the update rate in a display? Thanks!! BRUNO AYRES SERRA

Hi again! I found a way to do this. Open the file procbook.ini at C:\Program Files\PIPC\DAT. Locate the line "Timer=5000". This value is in miliseconds, so I changed to 250 ms and it orked fine! The display is updating very quicky! Beware of de CPU load if your display is full of points. I hope this information become useful for someone. Thanks! BRUNO AYRES SERRA

Hi Bruno, Sorry I missed your post but glad you found an answer. Also, be aware if you have any VBA code in the "Display_DataUpdate" event whilst having such a fast frequency of updating. Principal Consultant

You're right. I'll pay attention on this. Is there any other way to increase the update rate? Going beyond, is there a way to have differents update rates for each display? Thanks! BRUNO AYRES SERRA

I'm aware of being able to adjust the refresh rate as listed above. However, is there a way to do it pragmaticly on a display by display basis? I would rather not have every display I have update at 0.2 seconds. I only have one display that needs that fast of a refresh rate. Also, I've been poking around (perhaps not enough) and have not found a way to temporarily stop the refresh from happening. It has been causing problems while there are particular display changes taking place due to VBA code exicution (namely when I pragmaticly change tag names).
