Returns TRUE if the function block is executed.

See Function - General Rules.

Remarks

  • This function block is automatically called if a Trigger Block is added to the Pipe Network, with user-defined settings entered in the Pipe Blocks Properties screen.
  • The Trigger object monitors a selected Fast Input and captures the time of a rising or falling edge event.
    • With the time and pipe position information, the Trigger object extrapolates the axis position when the Fast Input event occurred.
  • Parameters to enter include:
    • The name of the Pipe Block.
    • The Axis where the Fast Input is located.
    • The number of the desired Fast Input.
    • Whether to trigger on the rising or falling edge of the input.

  • Trigger objects are normally created in the Pipe Network using the graphical engine.
    You do not have to add MLTrigInit function blocks to their programs.
    Parameters are entered directly in pop-up windows and the code is automatically added to the current project.
