We are using PAC Project Basic with Windows XP to control atmospheric conditions within enclosed chambers. After saving  our interface in PAC Display and loading Runtime, our program operates normal for roughly 45 minutes...then crashes. A MS Windows error pops up asking to send an Error Report and we can restart Runtime and it runs great until the next crash in about 45 minutes time. I did some searching on here and took the following actions: -Un-checked "Enable Runtime Operator Action Logging" in PAC Display "Configure/Runtime/Security". -Removed all anti-virus software. Neither made any difference, it still crashes as it did before. I know others have had this same issue...any help is appreciated as we are unable to do any long term testing when our system keeps malfunctioning like this. Thanks, Travis    Report

Its amazing what obscure features of Windows will intereact with PACDisplay functionality.  One of my favourites is  KB49838 associated with memory leaks when you do not use the defualt windows theme for your desktop. Its not clear whether you are using XP ServicePack2, but I would strongly recommend it if you are not using it. Another popular one is  KB49838 associated with random crashes due to a conflictive .dll file that may be preinstalled by other software running in your PC.  Version control and overwriting existing .dlls has never bwwn a strong point of the Windows operating system.  You can find a patch at www.opto22.com/site/downloads/drilldown.aspx?aid=3535 Hope this provides some help.  It would also be helpful to know the revision of PACProject you are using.    Report

I have been in contact with some Opto support people and using the articles and suggestions they provided along with my research, this is what i've tried up until now: -Switched from Windows XP package 2 theme to Windows Classic, as mentioned in a thread in this forum. -In PAC Display, un-checked "Enable Runtime Operator Action Logging" in Configure / Runtime / Security. -Removed all anti-virus software from my laptop. -Removed original PAC Project version 8.1 we were using, installed version 8.2 in place of it. -Removed file "cw3220.dll" and replaced with the updated file. I also heard from an Opto support advisor that our computers may be the issue. I'm using an ancient IBM T30 and my fellow intern is using an IBM T43.    Report

But its not a bad idea to try another computer although don't try one thats "too new" or you may find a different problem. See KB80147 OptoDisplay, ioDisplay and PAC Display may have problems on PCs with dual-core processors, although according to Opto22 this is fixed with 8.2a software. Its not such a bad test to set up a new simple PACDisplay project, scanning a few variables,  trending, reporting, alarms using relatively high scan rates to see whether the computer falls over.  Is so, its probably not your Display project that is at fault and could indicate a hardware problem.  If you project runs successfully on another computer then its definitley your laptop.    Report

I switched all of the software over to a very lightly used IBM T41 because the T30 was about to die. I ran the same program, and it crashed after 40 minutes of Runtime. The T41 has 512MB of RAM, which should be enough for this program...I thought. I also played with the settings in PAC Display under "Configure - Runtime", but nothing seems to be working. I then created a simple Display program with only one input tag and one window. I ran the program for 2 hours and it never missed a beat, no errors, nothing. Perhaps a data logging/storage issue? I archived my strategy and display program and sent them to a tech support at Opto. He's going to run the program and see if he gets the same error. If he doesn't, like you said, we'll know that our laptops are most certainly at fault.    Report

We discovered that the combination of our old(er) laptops and our large Display program were too much for our system to handle. To "lighten the load", we staggered all of our refresh rates on our trends and set conservative refresh rates for our input values. As a result, we are now able to run our program for long periods of time with no errors. Although, we are getting the same error on occasion, but only if we hit two keys at once, click too many times, or little things like that. We're still working on trying to figure out this error.....    Report

And as a side note, my computer is a P4 2.3GHz with 1GB RAM and XP SP2.    Report

I received a zip file containing the latest Runtime beta updates from an Opto rep and extracted them into my PAC program. We've been beating on the keyboard and mouse trying to create the error again (which we could easily do prior to the updates), but it seems to have been repaired because we have been running all day with no errors. Give that a shot and see if it helps your case.    Report
