Property Value

Valid values of this property are in the range from -1 to 2147483647 (Int32.MaxValue).

Unit of measurement is ms.

The default value of this property is 15000.

Exceptions
ExceptionDescription

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 is actually an operation timeout that is used when making server or endpoint discovery operations (such as the OPC UA FindServers and FindServersOnNetwork service calls).

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