Remarks

  • The ID argument is the identifier of the signal resource.
    • Use the SigID function to get this value.
  • The IN argument is used as a Play / Pause command to play the signal.
    • The signal is not reset to the beginning when IN becomes FALSE.
    • Instead, use the RST input that resets the signal and forces the OUT output to 0 (zero).
  • The TM input specifies the minimum amount of time in between two changes of the output signal.
    • This parameter is ignored if less than the cycle scan time.
  • This function block includes its own timer.
    • Alternatively, use the SigScale function if you want to trigger the signal using a specific timer.
