Determine number of selected channels for traditional DAQ

[pgraebel]

The blocks of "DAQmx Task" and "traditional DAQ Channel" look quite similar (see attachments). The DAQmx block ist an individual selection of channels and I am able to determine the number of selected channels.

Now I am trying to determine the number of selected channels of a traditional DAQ, but the DAQmx property block does not work here. I did already try some blocks form the trad. DAQ palette but failed.

Any idea?

The new attachment is showing channels for traditional DAQ (upper) and DAQmx (lower). You can clearly see a selection of channels inside the traditional DAQ box.

How do I determine the number of channels? The DAQmx way to do that does not work for the traditional.

In traditional DAQ there was more than one way to specify the channel list. Assuming that your image shows how you will use it your channel list is just a comma delimted string. Wire that constant to a an spreadsheet string to array node and specify "comma" as the delimiter and the number of collumns should tell you the number of channels.
