GPL program variables

This series of parameter database items have been set aside for use by GPL application programs to support development of custom web interfaces. These strings and variables can be written to and read by the standard web pages. These values are also fully accessible from a GPL program via the Controller.PDb and Controller.PDbNum properties. Once the controller is booted, the operating system never automatically alters any of these values.

The values of these variables are stored in their own parameter data file, gpl_vars.pac .

1892 GPL program NVRAM variable array Int32 8       Application specific.  An array of 8 values that are stored in the optional NVRAM device, not in the system configuration files.

These values permit GPL programs to store 8 integer values that are automatically preserved in case of power failure. These values can save key dynamic status and state information.

If no NVRAM device is present, these values are all zero.
