If you want to trigg signals on the move without having multitasking on your ABB robot, triggLIOs would help you. This signal would help you to set values to different types of signals (up to 50). One could set Digital Output / Analog Ouput / String Output or Group Output signals with help of this command. This commands also allows one the choice to trigger signals based on distance / time after the start or distance to the end of the movement.
See below examples from RAPID (ABB robots programming language) reference manual:
