Global Variables
Global variables define channels, which can then be used in sequencer, math and displays.
New variables can be added with the + button. You can either remove one variable with the - button or Delete all variables. You can also Export the variables to an *.xml file or Import them from *.dxs, *.d7s, and *.xml files. When importing, you will be asked whether you wish to keep or delete existing variables.

The Unique ID must be defined, which is used as a reference for everywhere else this variable is used. Name can be freely defined, as well as color and unit.
Data type can be:
- Floating point - floating decimal point, you can also define the number of decimals
- Integer - whole number
- Text - text written by the user
Channel type can be:
- Single value - storing only one value per entire measurement
- Async - adding a value each time the channel changes from sequencer or math
Start value can be selected from:
- Last value - variable will remember the last value
- Default value - it will always start with a defined default value
Default value sets what value the channel has when starting up.

Export order defines the order in which the variables will be exported. If left at Default, it will be according to their indexes.
