SignalLineNumber Property

Syntax

CWIMAQPulse.SignalLineNumber

Data Type

Long

Purpose

Line number of the signal line that triggers the pulse.

Remarks

This property specifies which signal line triggers the pulse generation when you set SignalSource to cwimaqExternalLine and cwimaqRTSILine.

Example

Private Sub Run_Click()
    Dim pulse1 As CWIMAQPulse
    Dim signal1 As CWIMAQSignal
    ' Add a signal
    Set signal1 = CWIMAQ1.Signals.Add
    
    ' Set the signal object to generate a pulse
    ' on external line 0.
    signal1.Action = cwimaqGeneratePulse
    signal1.Line = cwimaqExternal
    signal1.LineNumber = 0
    
    ' Add a pulse.
    Set pulse1 = CWIMAQ1.Pulses.Add
    
    ' Set the pulse to have a width of 1 second
    ' after the initial delay of 1 seconds.
    ' The pulse is generated immediately after
    ' RTSI 3 is asserted.
    pulse1.Action = cwimaqSingle
    pulse1.Delay = 1#
    pulse1.Width = 1#
    pulse1.SignalSource = cwimaqRTSILine
    pulse1.SignalLineNumber = 3
    pulse1.SignalPolarity = cwimaqActiveHigh
    pulse1.Units = cwimaqPulseUnitSeconds

    ' Set this pulse1 as the pulse1 that the signal1
    ' object generates
    Set signal1.pulse = pulse1
