This register indicates the current step that is running on Task n. The Current Program register indicates the current program.

Note:
If this register is referenced in the action portion of a step in a user program, it will give the number of the step that was previously executed by the task. If referenced from the Link or from any other location, such as the Program Triggers or from a host controller, it will indicate the current step.
Therefore, this register is best not used in the action portion of a step in a user program.
