In the interface startup bat file, you can specify the VSAs to be archived in the /att field in the ExDesc of the PI tag.
The VSA specification in the /att is a relative offset into the actual VSA offset specified by the /evc command parameter. Consider the following Attribute PI Tag Identity when the startup command line contains the event category definition /evc1=1,601,602,603,604,605 or the equivalent entry exists in the Interface Configuration Utility:
When /att=COND,VSA602,VSA604,VSA605 is specified then those specific VSAs are archived.
VSAs requested in this field must be configured either manually in the startup batch file or by the Interface Configuration Utility. Verify correct configuration of the /evc command argument to ensure correct behavior
Thank you Eugene,
