I just thought that this property is property of the client that I've already initiated. Its the property of the type it self.

I've found it :)

I do not quite understand the question, because if you can get to EasyUAClient, you should also be able to get to its AdaptableParameters property.

If you have a code that does not compile, please post it here...

EasyUAClient.AdaptableParameters.Session.HoldPeriod = 60*1000;


which using should I include in order to get AdaptableParameters?

No - we are not using Isolated property.

I will use you advice and try with longer holdPeriod and then check if it helped.

It appears that the connection cannot be established at all. For the reason, we would probably have to employ a low-level diagnostics tools like WireShark.

But, I have a suggestion: If you are just doing periodic reads and no subscriptions, increase the hold period, i.e. the period for which the QuickOPC (EasyUAClient) keeps the connection to the server open after use. The default is fairly short (5000 milliseconds = 5 seconds), therefore if you are initiating a read every 10 seconds, it is likely that the connection is getting closed (always or sometimes) in between the reads. That is quite inefficient anyway.

Assuming that you are *not* setting the Isolated property of EasyUAClient to 'true', try this - before making any OPC operations:
EasyUAClient.AdaptableParameters.Session.HoldPeriod = 60*1000;

It will increase the hold period to 1 minute, and the connectin should therefore stay open all the time you are doing the periodic reads.

Best regards

Have you followed the hint in the error message,

check the diagnostics on the server side, if possible.

?

BadSecureChannelClosed - error was created by UKPR
Hello QuickOPC team,

I am getting following error:
OPC-UA service result - BadSecureChannelClosed.
---- SERVICE RESULT ----
StatusCode: {BadSecureChannelClosed} = 0x80860000 (2156265472)
-----
StatusCode: {BadSecureChannelClosed} = 0x80860000 (2156265472)
---- REMARKS ----
The server may have rejected the connection because it does not trust the client (e.g. certificate problem); check the diagnostics on the server side, if possible.
A possible cause of this error could also be that the OPC-UA server is not running, or that it has rejected the connection due to security reasons.

My app is simple UA client reading manually 1 value from OPC Server. I need to read the value exactly e.g. 10sec. (I know that there is better option with subscription - upgrade of the app in progress)

After random time - sometimes 1day sometimes one week or few hours after rebooting of the app (running as a service) I am starting to get this error.

What could be possible causes? There is no security right now between client and the server. Server is KepServerEX5.18

Best regards
