WCCIL00event - PARAM/WARNING - Datapoint does not exist, DP: :_original

Enclosed you'll find the explanation for a log message which can be displayed during startup of the project or during runtime. The log message is written to the PVSS_II.log-file.

WCCIL00event (0), 2012.08.06 12:39:46.358, PARAM,WARNING, 7, Datapoint does not exist, DP: :_original, MAN: (SYS: 2 Driver -num 1 CONN: 1)

Log message with symbolic names:

WCCIL00event (0), <TIMESTAMP>, PARAM,WARNING, 7, Datapoint does not exist, DP: :_original, MAN: (SYS: <system-number> Driver -num <driver-number> CONN: 1)

This log message will occur during startup of the driver when the structure of the internal datapoint type _DriverCommon is not correct, e.g. when some elements are missing. This could cause an incorrect functionality of the driver.

To solve this problem, follow the steps below:

  1. Start a PARA module and select a datapoint of the DP type _DriverCommon.
  2. Open the tree to display all elements for this datapoint.
  3. Start a text editor.
  4. Open the ASCII file <WinCC OA-installation>/dbdfiles/<current version>/update_dptypes.txt.
  5. Search for _DriverCommon._DriverCommon.
  6. If an entry is found, proceed with step 9).
  7. If you couldn’t find an entry, follow the steps below.
  8. Close the file <WinCC OA-installation>/dbdfiles/<current version>/update_dptypes.txt.
  9. Open the ASCII file <WinCC OA-installation>/dbdfiles/<current version>/dptypes.txt.
  10. Search for _DriverCommon._DriverCommon.
  11. Compare the displayed content at the tree with the information written at the ASCII-file.

If a difference was found, mark the lines beginning with _DriverCommon._DriverCommon down to the line previous to definition of the next DP type, beginning with <dp-typename>.<dptypename>.

  • Copy the marked content.
  • Open a new text file.
  • Insert the following line: TypeName.
  • Insert the copied content.
  • Save the file at the directory <WinCC OA-project>/dplist/_DriverCommon_DPT.dpl.

To apply the changes to your project, import the file _DriverCommon_DPT.dpl using the ASCII manager and the option to modify existing datapoint types.

Afterwards the project must be restarted.
