Requirements

Important:
Note that if you use statistical functions and have specified the "Always start calculation at" time on the synchronization tab of the data point function, the start time for the report has to be the same as the "Always start calculation at" time of the DP function (otherwise, the report won't get the required data).

Warning messages appear at the start of the Excel Report if any of the following conditions are not met:

  • Missing License: The button to start the Excel report is disabled if the license is missing.
  • Excel installation: Checks if Excel is installed on the system.
  • Excel version: Verifies that Excel has the correct bit version (32/64-bit) as required by the registered COM manager.
  • COM manager registration: Confirms that the COM manager is registered with the correct version.
  • Check availability: Determines whether these checks can be performed.

Example of a warning message:

Potential version mismatch between registered COM Manager and WinCC OA, report may not run,
