Filter for DPT, DP and configs

Data point types

The command line option-filterDpType typenamerestricts output to one or more data point types. This option can be used more than once.

Data points

The command line option -filterDp dpname restricts output to the specified data points. Dpname is in the dpNames format, that is, you can also use wildcards (see Control function dpNames()). This option can also be used more than once.

If you specify the structure of a DP and you want to make an ASCII out of all elements belonging to this structure, you must indicate this with ";" after the structure in the option -filterDp. For example, the following command returns all original values of the elements belonging to the structure ExampleDP_BarTrend:

WCCOAascii -filterDp ExampleDP_BarTrend; -filter O -out test.dpl

PowerConfigs

The command line option -PowerConfig restricts output to the specified data points with configured PowerConfigs and is an essential feature while using mass configuration (see also PowerConfigs, basics). The import is made with the format V 3 (for more information on V 3, see the chapter Templates/DP lists, basics). Using this format, you can delete DPs whereby the appended PowerConfigs are also deleted.

When exporting a complete data point type (including master data point, data points and configs), the specific internal data point of type _DynamicDatapoints is exported when using mass configuration and defined PowerConfigs. For example, when exporting the data point type Valve, the internal data point _dt_Valve with the original values has to be taken into account). This applies when exporting with other formats than V 3 or V 4. If the data point type with the PowerConfigs is deleted in the PARA and newly created via importing the exported file, this can cause problems with the PowerConfig configuration of data points. The problem occurs when the internal data point that manages the PowerConfig settings is not taken into account.

If you want to filter out just one data point, specify this filter: -filterDp data point name* .

Option -filterFile

If the number of data point types and data points to filter is high, you can use the option -filterFile filename. The file filename is read line by line and parsed as follows:

• Ignores leading spaces and tabs. Ignores empty lines and lines beginning with #.

• The keyword DPTYPE: means data point types to track.

• The keyword DP: means data points to track.

Both keywords DPTYPE: and DP: can occur more than once in the file.

# Filter file for  Test 1
  DPTYPE: Type1
  Type2
  Type3
  DP:
  Motor01*;

Insert a blank line at the end of the filter file in order to have the correct functionality when filtering data.

Command line:

WCCOAascii -proj [projectname] -out [filename including path] -filterFile [filter file name including
 path]

e.g.

WCCOAascii -proj WinCCOA_Proj -out D:\DPs\DPTest -filterFile
D:\WinCC_OA_Projects\WinCCOA_Proj\dplist\dpfilter.dpl

After output, the ASCII file test1 contains the data point types Type1, Type2 andType3 and all data points starting with Motor01.

Configs

The option -filter P can be changed to specify which configs to output. The configs can be specified using their neutral or their German name.

-filter P:_address,_smooth,_alert_class,_alert_hdl

DP Comments in _common config

The data point comment is split into the segments comment, format and unit, which are all stored separately.
