Paul,
You asked:
...when I wired a numeric control with a defined unit (in this case "m") to an expression node, I get a bad wire connection with the associated error "You have connected numeric data types that have incompatible units". Same problem when I tried with and "formula node". I checked the Labview help file but the issue is not addressed.
Is this a fundamental limitation of the expression and formula node or is there a way to use these primitive with variable with units.
The Convert Unit primitive will convert a number with a defined unit to a pure number for use with, e.g., the expression and formula nodes. Specifying the unit within the Convert Unit primitive puts the decimal in the right place, chooses English or metric units, etc., so using "ft" on a wire containing "1 m" will give 3.28084... as the output.
