Free text to describe Decoder functions. This text is also used as a 'tooltip' in the locomotive control dialog.

Note: Keep it brief to fit in Mobile Client buttons.

This is mandatory for saving a function definition; Without a description all other settings are lost.

)( Pushbutton

The option determines the behavior of the associated Function key / button in throttles.
Deactivated = Switch. The function is alternately switched ON and OFF by pressing a button.
Enabled = Button. The function is ON only for the duration of the button is pushed.


The function code is mainly for selecting the corresponding icon on mobile devices.


With the timer box the function can be deactivated automatically. Values greater than zero are activation time in units of 100ms.
Starting with Rev. 14571+, the maximum time is 10,000 x 100 ms = 1000 s or 16 2/3 minutes.
Values greater than zero are interpreted as time. (0 = switching function, 1 = pulse function with 100 ms, 2 = pulse function with 200 ms, etc.)
With a null entry, the function remains activated until it is deactivated by an event, an action or manually.

Note: Due to the slot management of the CS track signal, noticeable deviations may occur if many trains running (High data traffic) and a Function time is short.


Pushing the tripple dot […] button opens the Function event picker dialog.\\. Events are optional, do not use it if you only want tooltips.

Function events will only work when running your locomotive in auto mode!
