PVSS00event - PARAM/WARNING - Datapoint does not exist, DP: :_original
Enclosed you'll find the explanation for a log-message which can occur during startup of the project or during runtime. The log-message is written to the PVSS_II.log-file.
PVSS00event (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:
PVSS00event (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 please perform the following steps:
1) start a para-module and select one datapoint for the dp-type _DriverCommon
2) open the tree to display all elementes 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
If an entry is found please proceed with step 9).
If you couldn’t find an entry the following steps need to be done.
6) close the file <WinCC OA-installation>/dbdfiles/<current version>/update_dptypes.txt
7) open the ASCII-file <WinCC OA-installation>/dbdfiles/<current version>/dptypes.txt
8) search for _DriverCommon._DriverCommon
9) compare the displayed content at the tree with the information written at the ASCII-file
10) If a difference was found please mark the lines beginning with _DriverCommon._DriverCommon down to the line previous to definition of the next dp-type, beginning with <dp-typename>.<dptypename>.
11) copy the marked content
12) open a new text-file
13) insert the following line
TypeName
14) insert the copied content
15) save the file at the directory <WinCC OA-project>/dplist/_DriverCommon_DPT.dpl
To apply the changes to your project you have to import the file _DriverCommon_DPT.dpl using the ASCII-manager and the option to modify existing datapoint-types.
Afterwards the project needs to be restarted.
