A single 'Globals-' sheet may be defined.
Any variables that apply globally, to all ID's may be defined here. If a device data (DD) variable is also defined, then the DD variable takes preference of the global variables
The first row of the sheet must be used as a heading row. Cell A1 names must be have a value of 'Variable'. Cell B1 names must be have a value of 'Value'.
The variables and their corresponding values may be defined below the heading row.
Duplicate variables on the Globals- sheet will be ignored.
If a duplicate variable is defined within a Data- sheet, then that variable will take preference over the globals variable.
