Is it possible to adjust the default time that Vdin buttons when pressed and held remain 'on' for?
We have a multi-master application using a MD4-10 and a MD4-7. On each we have momentary buttons commanding functions that are slow in operation meaning the button has to be pressed for some time- By default the buttons while still pressed go to the 'off' state by Iqan even though still pressed requiring the user to press again- this is not acceptable to the user. We cannot latch the buttons for safety reasons. The buttons seem to switch to 'off' after about 10-12 secs on the MD4-10 but longer (approx 20 secs) on the MD4-7.

No, we have decided that we do not want to extend the timeout anymore, as that might tempt people to start using the VDIN touch buttons for motion controlling functions. That is not their intended purpose.
All VDIN, both those on the MD3 and on the MD4, are handled by the graphics portion of the software. Unlike the physical I/O and internal calculation channels, the graphics is not running with real-time performance, and is thus not suited for machine control.
With the touch buttons, it is even more important with a timeout, to distinguish deliberate button presses from other influences.
Touch button timeout has been updated to 30 seconds for all MD4 models in IQANdesign 5.02.
