In Function Block and Menta Editor programming, once the unit of a function block has been set to a specific type, there is no option at the top of the list to set it back to "blank".
- Function Block Programming
In TAC Vista Menta, the first option in the list of units for a function block is just a blank field. The blank field means that there is no unit type selected. Function Block and Menta Editor programming in SmartStruxure do not have a blank field that can be selected.
Instead of using a blank field to signify that there is no unit type, SmartStruxure programs use a "NoUnit" designation. "NoUnit" can be found in the list of units alphabetically.
