Configuring the PlantScape ODBC Driver
PlantScape Server and Client Configuration Guide 405
WHERE (PointID=’sinewave’)
Note If no value is specified for LogTimeStamp, then, by default, only events
generated within the last 24 hour period are returned.
History Tables
Nine history tables from the PlantScape database are visible via the ODBC driver.
These are:
History1HourAverage
History1HourSnapshot
History1MinSnapshot
History24HourAverage
History24HourSnapshot
History5SecondSnapshot
History6MinAverage
History8HourAverage
History8HourSnapshot
Unlike most other tables, history tables cannot be opened and viewed directly.
You need to build a query that specifies the point (or points) whose history you
are interested in. The first columns in a history table are shown below. All history
tables have the same columns.
To specify the point whose history you are trying to retrieve, you must set
ParameterXXX to equal the point ID and parameter.
