Description

System.ArgumentOutOfRangeException

Remarks

Keep-alive: Client monitors the Server, whether it responds to Publish.

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

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