the true and false values. The displayed text may be preceded by a description on the left
side (prefix), e.g., the name, as well as on the right (suffix), e.g., the units.
In order to edit the variables, it is recommended to use the NVBooleanWritable
component from iSMA_platAAC20 kit. To edit the value of the BoolLine component select
true in the Editable slot, and provide the user with a write access to the component. To
make sure that the value on the LCD is synchronized with the changes in the
NVBooleanWritable component the “link back-forward” strategy needs to be applied.
There is a possibility to change the value from LCD by selecting the Set action. To do this,
use the up/down arrow keys to switch between the values of true/false.
