Amount of DAQmx channels

[s.h._tech]

hello everyone,

I have a channel selector and can select multiple channels. The datatype of this control is 'DAQmx- physical channel'. Is there a property node for the amount of channels select?

I found this workaround

and made a little VI that fits my purposes.

Maybe there is a simpler solution?

I don't think it would be possible since the DAQmx Physical Channel control does not validate the channels selected (you could even type in any text) and there is more than one format for specifying multiple channels.

This Physical channel control data is validated only during creating a task and hence you would observe the same in the example you have posted, they would create a task and get the channels part of it.
