Assigning an Input to a Trigger
This menu appears only if you answered YES to the Edit Segment
Triggers menu. Use it to assign one of the controller’s eight digital
inputs to a segment trigger. You can assign any digital input to any
trigger. You can also assign the same digital input to multiple triggers.
Selectable Values: Any digital input from 1-8, or None (no input
assigned). Setting a trigger to None disables it.
Changing a Trigger’s True State
Use this menu to toggle a trigger’s true state On or Off. This menu
appears only if you answered YES to the Edit Segment triggers menu.
Selectable Values: Off or On.
Latching or Unlatching a Trigger
Use this menu to make a trigger latched or unlatched.
• A latched trigger is checked once, at the beginning of a segment.
• An unlatched trigger is checked constantly while a segment is run-
ning. If an unlatched trigger becomes false, the segment timer stops
and the loop goes into trigger wait state.
Selectable Values: Latched or Unlatched.
