Actual Queue Size

Associated with: OPC UA Points

When Geo SCADA Expert requests that an OPC UA server starts to monitor an item, that OPC UA server will respond with the actual values that it is using for such monitoring. This includes values for some of the properties that you can configure on the configuration Form of the OPC UA Subscription or OPC UA Point. The 'Actual...' series of status attributes indicate the values that the OPC UA server is actually using, which might well be the same values as those configured on the configuration Form of the OPC UA Subscription or OPC UA Point.

The Actual Queue Size status attribute indicates the actual value that the OPC UA server is using for this property. This might differ from the value that is configured for this property on the relevant OPC UA Point Form (see Configure the Queue Parameters).
