hello,

The lines "m_EasyUAClientCoils_MonitoredItemChanged PlantModel 2406 Exception" has been called with .Exception != null.
about the EasyUAClient_LogEntry between the time of last correct notification, and the piece of log that you have posted - i don't find the log file now so i can't answer this question.
about the delay - yes i mean 6 minutes, and not 6 seconds.
about the version - i have mistake, the log file was created with version 5.32.1063.1.
i will try to reproduce this problem with full logfile and than i will contact you again.
thank you for your time.

Do I understand it correctly that the log lines below that have "m_EasyUAClientCoils_MonitoredItemChanged PlantModel 2406 Exception" indicate that MonitoredItemChanged event handler has been called with .Exception != null ?

Is there any EasyUAClient_LogEntry between the time of last correct notification, and the piece of log that you have posted?

And (please apologize for what may be stupid question, it is just to verify what seems a bit weird), did you truly mean 6 minutes, and not 6 seconds? I am asking because the piece of log you sent appears to have 6 second time span.

Also note that version 5.30 is no longer supported.

Best regards

monitorItemChanged has delay was created by adid@contel.co.il
hello,

i am using QuickOPC 5.30.1114.1 and normally the monitorItemChanged is working,
but i saw one time that it takes the opcLabs 6 minutes to operate the monitorItemChanged function ( 6 minutes were passed from the time the tag was changed till the monitorItemChanged function was fired ). when i watch for the opcLog file that i have crerated from the logEntry i saw :

2015-03-18 10:39:28 – EasyUAClient_LogEntry Message The OPC-UA subscription publishing has stopped on the client session to endpoint URL "opc.tcp://10.1.101.136:49320". Further such errors on this session will not be logged.
