The Shared Variable Export Manager is an application which created/controls Export Groups (a group of NI SVE variables to be exported to flat text file). Each group runs independently and can create comma separated variable data files, JSON sensor measurement data files, and JSON sensor state files.

The manager application has the ability to perform the following actions:
- Start a group
- Stop a group
- Reload a group
- Add a new group
- Remove a group
- Open the configuation file of a group
- Shut down all groups and close application

All configuration files placed in the auto load folder (typically .\ExportManager\ExportGroups\) will automatically load when the application is loaded.
Due to the nature of the Shared Variable Engine (SVE), each variable is "opened" when the group is loaded. This can cause long start-up delays when connecting to a large number of variables.

Configuration of an Export Group

The configuration file for an export group is ASCII text NI_LVConfig format, where [square brackets] indicate sections and variables = value.

Each config file uses the section [General] for logging information and a set of [Variable_IDs] for export variable configuration. Below is an example of an export group with two variables.

The [General] section has the following variables:
There are no required fields, but no exporting will occur by default

Each variable to be exported needs to be defined using it's own section (don't call any variable [General] or it will be ignored, also give each section a unique name).
A [variable_id] section has the following variables:
There are two required fields:"path" and "datatype"
