Specifies a scan time to update OPC UA Tags from an OPC UA Subscription that is used by an OPC UA Server. This property is represented in milliseconds, can be changed after communication starts, and it is used only when the Enable property is set to True. When configuring this property in all OPC UA Tags available in an application, it is recommended to increase this property's value for those OPC UA Subscriptions not varying much in a device, thus allowing other OPC UA Subscriptions of OPC UA Tags with higher priorities to be read more frequently, increasing application's performance and responsiveness. The default value of this property is 1,000.
