Hello,
unfortunately I find your report too broad to be able to tell more at the moment.

You mentioned that you have problems with "OPC Servers". That's more issues, as the causes might be different. Please one specific issue with a specific server (the one that's most important to you first), and we will work on that first. For that selected server

1. Which OPC server are you connecting to? Is it local or remote?
2. Are you able to work with it using the pre-build .NET Demo app that comes with QuickOPC.
3. Are you able to connect to that server using some other OPC client?
4. What steps have you taken, and what was the observed versus expected behavior?
If you get an exception, please copy its text and other details (the .Source property, .InnerProperty and recursively down) and post it here. (I know you included the picture of the exception, but it is not clear whether you get the same error in all cases).
5. If you are doing it from your own code, post the code here.

Also note that in the little piece of code that can be seen in your image, you are specifying the item using a "browse path" instead of its ItemID. While this is possible, it is, in general, VERY SLOW, and should be avoided if at all possible.

Regards

Dear Zbynek,

the demo version could not read the opc tag values.we are getting timeout error.we are getting timeout error.




we are not able access few OPC servers. so we updated the OPC Enum from 32 bit to 64 bit as per the below link.

right now we are using Visual studio 2017.
.NET version 4.6.1

we are trying to access the OPC Servers on local host. not even remote.

please suggest us to overcome the issue.
