1. You can use only the 16 input points X0.0–X0.15 of the PLC in S
interrupt service program to start the function. Note that S
counter.
2. Select the high-speed counter HC device in S
start the counting function.
3. The instruction stores the captured value from the high-speed counter (32-bit) in D when the interrupt occurs. The
instruction stores data when the interrupt occurs, and is not affected by the PLC program scanning.
4. The instruction operation is shown below. The input interrupt is triggered by the falling edge.
  When the execution of the instruction starts, the value in D does not change and you can enter the default
setting value.
  When the interrupt in S
and stores it in D.
