Hello,
the problems should be fixed now. Please download the current version (5.63.221.1 or later), rebuild, and retest.

Thank you for reporting the issues.
Best regards

Hello,

Thank you for the additional information. I was able to reproduce both issues. I have forwarded this to the programmer who works on this part. I will post here when I have an update.

Thank you for reporting the problem, and best regards

Hello,
sorry, I wasn't clear enough about the exception. The unsubscribe exception only occurs if the reconnect did not work. With an existing connection, Unsubscribe works without any problems. So I think that these are not 2 separate problems.
to 1.
The version I tested with "EasyOpcNetDemoXml" was 5.63.121.1. In my application I tested 5.63.194.1. Without change.
to 2. and 3.
I have attached a text file with the windows log entries.

to4.
I've tested both and it makes no difference.

Thank you

Hello,
so there are 2 problems (no reconnect, and the exception), and I want to look into both of them.

Can you please provide some more information:

1. I also need the build number of the software (the digits after 5.63). Please locate one of the OpcLabs.*.dll assembly files in File Explorer, right-click on it, select Properties, and find out the full version&build on the Details tab.
2. What are the details of the "system exception".
3. "The error message is in the Windows log" - please provide all relevant information from the Windows log.
4. "after a connection to the OPC XML servers is lost": In your case, is it due to network problems, or because the server is not running/is shut down - or it does not matter?

Thank you

Hello Support
I have the problem that after a connection to the OPC XML servers is lost, the subscriptions are not restored.
To fix this, I built in a function that deletes all subscriptions (EasyDaClient.UnsubscribeAllItems), deletes the instance and creates new ones.
Unfortunately I get a system exception with UnsubscribeAllItems that closes my program.
I have the same behavior with the supplied demo program "EasyOpcNetDemoXml".
Please try if you have the same result and do the following:
-Start EasyOpcNetDemoXml
-Leave all addresses on default.
-Click Subscribe
-Disconnect from the server
-Wait for the message in the Exception field
-Reconnect to the server

A connection is no longer established on my systems

-Click Unsubscribe
program closes
The error message is in the Windows log
At least that's how it is on my systems.
can you reproduce this?

My version is 5.63

thanks in advance
