The name of the file comes from a PcVue text variable. Here the unit’s name is “xunit”.

1. If the text variable’s value is a file name (e.g. xfile) without a suffix, the file will be placed in the current project folder …\TH\xunit\xfile.wri.
2. If it is an absolute path (e.g. C:\xp1\xfile), the file will be stored as follows:
   c:\xp1\xfile.wri.
3. If it is a relative path (e.g. Xp1\xfile), the file will be placed in the current project folder \TH\xunit\xp1\xfile.wri.
4. When the text variable’s value changes, the most recent .WRI file will be renamed with a .DAT extension.
5. If the text variable doesn’t exist or its value is empty or uninitialized, the file will be placed in the current project folder \TH\xunit\ and it will be named as before (e.g. H00000.wri).

The saved files for a series can be dynamically changed by updating a text variable’s value. (SCADA Basic program or mimic.)

For example:

vartext = c:\xp1\2011_03_31_10h00.wri

5 minutes later, it is decided to change the destination file forcing a text variable to:
vartext = c:\xp1\2011_03_31_10h05.wri

5 minutes later, it is decided to change the destination file again:
vartext = c:\xp1\2011_03_31_10h07.wri
