Breakpoint properties:

  • Enabled - Enable/Disable Breakpoint
  • Tags - MISB 601 Tag
  • Condition - Logic expression to evaluate
  • Value - Condition Value
  • Deviation - Deviation in % (or in seconds, for time) for eq* (equal to) or **neq (not equal) conditions. Serves as an accuracy threshold

Select the required mode and MISB tag(s), type in an expression and the corresponding value in the Condition and Value boxes (such as gt > 90) that must be true for the breakpoint to be triggered.

For eq and neq operators, you can add the required accuracy (by specifying the Deviation).

For example, let's say you want to set a breakpoint to be triggered when the altitude is 1000 m. The platform metadata may never report the exact 1000 m value, so we may set the accuracy of a few meters (+/-) or so. This can be done by defining a deviation. The percentage is based on the available range (you'll get a hint for every tag). For time-based tags, you may set an accuracy in seconds.

Expressions
