Description
This is a value that indicates whether the tag value is late data or real-time data. If the property value is 0, then Wonderware Historian treats the tag value as late data. If the property value is 1, then Wonderware Historian treats the tag value as real-time data.
- Late data arrives at the Wonderware Historian with a timestamp later than the current Historian time.
- Starting with Wonderware Historian 2014 R2, the real-time data window is only applicable for store-and-forward data from a remote IDAS. The real-time window is the maximum delay, relative to current time of the server, in which data is considered real-time by storage. The real-time window can range from -30 seconds to +999 milliseconds of the current server time.
For more information, see the Wonderware Historian documentation.
