Exception

Description

System.ArgumentOutOfRangeException

The value of an argument is outside the allowable range of values as defined by the invoked method.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

This parameter is not interpreted by the component; it is simply passed down to the OPC UA Stack for processing.

If the session cannot be closed in a timely manner, it is considered closed anyway, and the component will not use the same session again. The timeout prevents the component from waiting too long or indefinitely for the confirmation. This means that any new requests to the same endpoint will open a new session, as with the properly closed sessions.

In order to obtain or modify this parameter, in the default state (when OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated equals to false), access UAClientAdaptableParameters.SessionParameters property of static OpcLabs.EasyOpc.UA.EasyUAClientCore.AdaptableParameters. If you have set OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated to true, you need to access UAClientAdaptableParameters.SessionParameters property of OpcLabs.EasyOpc.UA.EasyUAClientCore.IsolatedParameters.

The getter method of this property is pure, i.e. it does not have observable side effects.
