Controls whether Legacy IO tags (Analog Status, Digital Output, etc.) are included as Multispeak tags for ScadaAnalogChangedNotification and ScadaStatusChangedNotification messages. This property also controls whether such tags appear in the GetAllScadaPoints list.
When enabled, this property can greatly increase the load on your servers. Legacy I/O tags do not have tag by tag control over publishing, therefore there could be a large number of notifications.
You can mitigate that by adding this property to a parent Context tag and setting it to 1 there. It will apply only to those legacy I/O tags below that Context.
If not set, only I/O and Calculations tags will be used.
