WCCIL00event - PARAM/WARNING - DP attribute was connected twice

WCCILevent - PARAM/WARNING - DP attribute was connected twice

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

WCCILevent (0), 2012.05.29 11:23:31.512, PARAM,WARNING, 90, DP attribute was connected twice, DP: System1:Pump1.status.value:_original.._stime, MAN: (SYS: 1 Event -num 2 CONN: 1)

Log message with symbolic names:

WCCILevent (0), <TIMESTAMP>, PARAM,WARNING, 90, DP attribute was connected twice, DP: <DPE-name>:<config+attribute>, MAN: (SYS: 1 Event -num 2 CONN: 1)

This log message describes that the DP element <DPE-name> was used several times for one datapoint function.

If you want to use several attributes (for the configs _original or _online) for the same DP element in one datapoint function, you have to ensure that all entries in the parameter list are grouped together.

Example for the correct configuration:

p1=DPE-A:_original..value
p2=DPE-A:_original..bad
p3=DPE-B:_original..value
p4=DPE-B:_original..bad
Example for an incorrect configuration:
p1=DPE-A:_original..value
p2=DPE-B:_original..value
p3=DPE-A:_original..bad
p4=DPE-B:_original..bad

To get the information which DP function has to be corrected, follow the steps below:

  • Make an ASCII export of the _dp_fct-config (filter P + _dp_fct in the ASCII-manager-panel).
  • Open the ASCII file with a text editor.
  • Search for the DPE name given in the log message.
  • If the DPE name is part of the parameter list and listed several times in the same line you have to scroll to the beginning of the line to get the DP element where the configuration has to be checked and changed probably.
