Specifies a scan time to update Tags from an OPC UA Subscription that is used by the server. This property is represented in milliseconds and 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 Tags available on an application, it is recommended to increase this property's value for those OPC UA Subscriptions not varying much in the device, thus allowing other OPC UA Subscriptions of Tags with higher priorities to be read more frequently, increasing application's performance and responsiveness. Default value of this property is 1,000.
