Explanation
1. This instruction performs mark alignment positioning. When the value of S
maximum 32-bit value (with a sign) and the output does not perform the ramp-down stop until receiving the mark
signal.
If the value of S is not 0 and the external interrupt does not occur, the target number output pulses are output. The
1
range of S is between -2,147,483,648 to +2,147,483,647, and the +/- sign means the positive or negative direction.

2. When the value of S is less than or equal to 0, the output is not enabled. If the output frequency is greater than the
2
maximum frequency, the PLC processes it as the maximum output frequency.
3. S can specify the M or X device as the input point. The input source signal is affected by the scan cycle if the
3
selected input point is not in X0.0–X0.15 in the PLC.
4. You must use the instruction by combining the input point number and the external interrupt program to achieve the
real-time ramp-down output. For the rising-edge or falling-edge trigger for the external interrupt, select the triggers
in the external interrupt program in ISPSoft.
A. Using the external interrupt (e.g. I0xx, I1xx): when the external interrupt occurs, the ramp-down stop is
performed after the mark signal is received. No operation is performed if the external interrupt is not enabled.
B. Without using the external interrupt (I0xx, I1xx): When the instruction is executed, the ramp-down stop is
performed after the mark signal is received if the rising edge occurs at X point or M device. It is affected by the
scan time.
5. The number of output pulses in the fore mask section is between 1–S
the fore- mask section function is disabled. When the number of pulses to be masked exceeds the value of S
instruction takes the target number of output pulses S
occurs within the number of output pulses to be masked, the external input interrupt is automatically invalid.
6. The number of output pulses in the rear mask section is between S

interrupt is automatically invalid. When S
