User Options for Data Exchange: CDF V2.0 Dialog Box

To open this dialog box, click the User Options button and select the Data Exchange tab. On the Data Exchange tab, double-click in the Value field of the CDF V2.0 option.

For the data exchange format CDF V2.0, you can make the following settings:

• Version

  Defines the version of the CDF file to use.

• Write variant structure

  Determines if INCA writes the complete variant structure of the data to the CDF file.

  Note
  The use of variant structures increases the file size and reduces the processing speed. It is recommended to activate the writing of variant structures only if required by the destination system.

  NO_VCD	No Variant Coding (default setting); INCA writes the data of a variant without variant structure to the CDF file under the SW-INSTANCE tag.
  VCD	Variant Coding; INCA writes the complete CDF V2.0 variant structure to the CDF file. The structures are defined within the SW-INSTANCE_PROPS-VARIANTS and SW-INSTANCE-PROPS-VARIANT tags.

• Write long name

  Determines if the long identifier (Tag LONG-NAME) is to be written in the CDF V2.0 file in addition to the variable name. Use of the long identifier is optional.

• Write display name

  Determines if the display identifier (DISPLAY_IDENTIFIER according to ASAP2, DISPLAY-NAME tag) is to be written in the CDF V2.0 file in addition to the variable name. Use of the display identifier is optional.

• Write calculated axis values

  Defines whether the variable axis values for the axis types CURVE, COM and RES should also be written to the CDF V2.0 file.

  Under the SW-AXIS-CONT tag the axis values are optional, if the axes themselves are listed under the SW-INSTANCE tag.

  The additional display of the axis values under the SW-AXIS-CONT tag is only required if the tool used for further processing cannot calculate the axis values required for the display.

• Write concatenated labels as cascaded instances

  Determines how concatenated labels of the a.b.c form are written to CDF V2.0 files.

  Yes	Concatenated labels are displayed as cascade in the CDF V2.0 file; Example: test.first is displayed as two interlaced SW-INSTANCE entries, whereby the variable test is defined under the first SW-INSTANCE and the variable first under the SW-INSTANCE on the next layer.
  No	Concatenated labels are still displayed as concatenated in the CDF V2.0 file (default); Example: test.first is under SW-INSTANCE displayed as test.first

• Value representation

  Determines how numerical values are written to the CDF V2.0 file.

  Decimal	Numerical values are displayed as decimals (default). The number of available decimal places determines the accuracy. Decimals with more than 17 decimal places are always displayed in exponential form; Examples: 123456789012345678 is displayed as 1.2345678902345678e18 0.123456789012345678 is displayed as 1.23456789012345678e-1
  Exponential	All numerical values are displayed in exponential form. The number of available decimal places determines the accuracy.
  Hexadecimal	All numerical values without decimal places are displayed as hexadecimals. At least 2 digits are used, e.g. 0x01. If necessary, more digits are used (Word: 4 digits, e.g. 0x0F0F; Long: 8 digits, e.g. 0x0F0F0F0F). Numerical values with decimal places are displayed as decimals.

• CDF file extension

  Determines, which file name extension is used for the CDF V2.0 file.

  .cdfx	Default; The .cdfx extension is recommended for files, which are further processed with a calibration tool.
  .xml	The .xml extension is recommended for files, which are further processed with a random XML tool.

• BOM

  Determines whether INCA shall write and accept CDF V2.0 files with a BOM (Byte Order Mark).

  Yes	INCA will write and accept CDF V2.0 files with a BOM.
  No	Default; INCA will not write or accept CDF V2.0 files with a BOM.

• Encoding

  Determines the encoding used and the related BOM when writing CDF V2.0 files.

  Universal (UTF-8, CP65001)	Default; INCA will use UTF-8 encoding when writing CDF V2.0 files.
  Wide character (UTF-16)	INCA will use UTF-16 encoding when writing CDF V2.0 files.

• XML layout

  Determines the way in which CDM will write the data exchange files.

  CrLf	Starts a new line after each tag. This option is the best compromise between visualization in standard text editors and performance.
  CrLf and indentation	Starts a new line after each tag and indents the content in relation to the structure. Select this option if good readability in standard text editors is required.
  condensed	Writes all information in one line, without any tabs or blanks for indentation. Select this option if you want to use the most compact format (small file size) with the best performance in reading and writing the XML files. This is especially useful if you will have huge data exchange files and if you use XML editors which automatically present the data in a structured way.
