Double push buttons of type “Numerical” are based on Numerical Indicators. The indicator
function is configured in the same way as for the corresponding indicator component. The
same data types are supported.
The left and right buttons allow the user to select a value from a given (configurable) range.
By default, the left button is used to decrease the value, and the right button to increase it;
however the opposite behaviour can also be selected through the
Action
parameter.
Minimum and maximum values for the allowed range must be defined (
Minimum value
and
Maximum value
parameters). The component will not allow the user to select a value outside this
range. Also, the
Short step
and
Long step
values must be configured. The short step determines
the increment or decrement that is applied to the current value on a short press of any of the
two buttons. The long step determines the increment or decrement that is applied (repeatedly)
to the current value when any of the two buttons is kept pressed, and until it is released.
Once a value is selected, it will be sent to the bus through the “control” communication object.
