4.9 Direct Functions
Both a blocking object and the function name can be defined for each button function. The blocking
object blocks the operation of the key when a logical 1 is received and releases it again as soon as a
logical 0 is received.
The function name is displayed centrally above the respective function and can either be set
permanently ("over text input") or set dynamically via the communication object.
If the status object for a function is not connected, the switching status is visualised, otherwise the
value of the status.
Identical parameters for all button functions are sind:
