*1: Index qualification can be used with AnA and AnU only.
Functions (1) Sets the timing clock for user (M9020 to 9024) specified at (D) to ON at the
scan count specified at "n1" and to OFF at the scan count specified at "n2".
(2) At the initial status (when the timing pulse input is off), the timing pulse is off.
(3) When "n1" and "n2" are set to 0, the timing pulse is as described below:
"n1" = 0, "n2"
≥
0: The timing pulse remains off.
"n1" > 0, "n2" = 0: The timing pulse remains on.
