Connection TimeOut?

The TCP connection itself is handled by the system, and so are the timeouts on such operation. Unfortunately there is no QuickOPC setting to influence this.

Connection TimeOut? was created by andis59
If I try to read from the server using
_easyUAClient.Read(uAEndpointDescriptor, scanSerialNumberTimeNodeDescriptor)
and the server is not available (not running, no tcp connection, etc)

I get an Exception

OpcLabs.EasyOpc.UA.OperationModel.UAException: An OPC-UA operation failure with error code -2138963968 (0x80820000) occurred, originating from ''. The inner OPC-UA service exception with service result 'BadTcpInternalError' contains details about the problem. ---> OpcLabs.EasyOpc.UA.UAServiceException: OPC-UA service result - Error establishing a connection. = BadTcpInternalError.


The exception occurs about 20 seconds after the read is executed.

This delay I assume is some TimeOut.

Is there someway to change the time?
