Yes, the trial runtime limit is 30 minutes. And you will get COM exception when it is over. But the code&message should be different, not a "Write not completed".

This possibly is a palm to forehead moment...

Right now I have this installed under a trial license. Let me guess that the trial allows the connection for about 30 minutes? It is consistently failing after what seems to be 30 minutes. I can confirm this is the case with the licensed version that I have.

Thanks for your help. Every project that I work on for customers I'm recommending this com object for development. It really is a great product you have here.

This may be QuickOPC problem if e.g. the EASYOPCL process has unexpectedly terminated (if out-of-process component is used). If it is running, it is more likely that the exception indicates a problem with the target OPC server. In this case, it would be an expected behavior on part of QuickOPC.

Your code should be handling COM exceptions from calls to QuickOPC methods (except those with "Multiple" in their name). Any error reported by the target OPC server would be a COM exception as well, and you cannot rule them out, so the code should not crash in this case.

I've installed the new version and it looks like I'm getting a different error. I've had all the services running simultaneously for about 40 minutes and then they all crashed one after another with the following exception:

exception 'com_exception' with message 'Error [0x800706be] The remote procedure call failed. ...

This is happening when trying to write to one opc item.

I'll keep you updated if I notice anything else.

You can check the installed version/build e.g. by using the About button in the utilities such as EasyOPC Options utility, or by right-clicking on any component executable (EXE, DLL), selecting Properties, and checking the info on the Details tab.

Best regards

Okay thanks for clearing that up. It would be kind of cool if I were able to check what build I had installed vs what is the latest build that you have released with what bug fixes are included with each build.

Thanks, I'll test this one out and let you know.

It is version 5.22.322.1 (or later). I wouldn't tell you to download it, if it wasn't there.

The build number is on the first page of the installation wizard.
