Write Historical Data dialog

You can use the Write Historical Data command to write a range of data in an Excel worksheet to a Continuous Historian database. For an example of how to use this command, refer to Writing Historical Data to a Continuous Historian Database in Books Online.

The Write Historical Data dialog includes the following fields and buttons:

Connection  Displays the name of the workstation node to which you are writing data. To select a node, click the browse (...) button.

Offset  If GMT is selected as the mode, you can select a time offset in +/-hh:mm.

After you select a range of cells from the Excel worksheet, the values appear in the data list under the headings: Tag, Timestamp (GMT), Value, Parameter Status, and History Data Is Valid (unless there is an error in the data).

Status  If the data is valid, displays the range of cells from the Excel worksheet and the number of samples. If there is an error, click Show Errors for more information.

Write Data  Writes the data in the data list to the Continuous Historian database.

Show Errors  Displays further details about any errors in the data. If there are errors, none of the data can be written to the Continuous Historian database.
