ID
ID of channel in session
Description
When working with the session-based interface, the ID

displays the ID of the channel. You set the channel ID when you add
the channel to a session object.
Examples
Create a session object, and add a counter input channel with
the ID 'ctr0'
.
s = daq.createSession('ni'); ch = addCounterInputChannel (s,'cDAQ1Mod5', 'ctr0', 'EdgeCount')
ch= Data acquisition counter input edge count channel 'ctr0' on device 'cDAQ1Mod5': ActiveEdge: Rising CountDirection: Increment InitialCount: 0 Terminal: 'PFI8' Name: empty ID: 'ctr0' Device: [1x1 daq.ni.DeviceInfo] MeasurementType: 'EdgeCount'
Change CountDirection
to 'Decrement'
:
ch.CountDirection = 'Decrement'
ch= Data acquisition counter input edge count channel 'ctr0' on device 'cDAQ1Mod5': ActiveEdge: Rising CountDirection: Decrement InitialCount: 0 Terminal: 'PFI8' Name: empty ID: 'ctr0' Device: [1x1 daq.ni.DeviceInfo] MeasurementType: 'EdgeCount'
