ID

ID of channel in session

Description

When working with the session-based interface, the ID property 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'
