4.7.0 Resources That Allow Dimension Changes
Float signals with fixed dimensions
A float signal is a type of test resource that typically has a fixed dimension assignment. An example of a float
signal is “Ch 1 Displacement” with a dimension of “Length”.
Float signals with dynamic dimensions
Some float signals can change their dimension during the test:
• Channel Command
• Channel Comp. Cmd
• Channel Active Fdbk
• Channel Error
• Channel Active Stabilization
Float signals that can change their dimension have a dimension type of “”.
Using the dimension type in tests
When designing tests, you typically use these signals with the Signal Scope. This allows you to view controller
signals that change dimension during the test, such as when the control mode changes. ( Test-Run Display
> Signal > Signal Scope).
You cannot use these signals for functions that cannot tolerate dimension changes while the test is in progress,
such as data acquisition, limit detectors, and so on.
