Delta AS Series Programming Manual page 564

Example 1
When M0 is ON, the DHSCS instruction is executed.
When the current value of HC200 changes from 99 to 100 or from 101 to 100, Y0.10 is ON, which outputs to the external
output terminal Y0.10 in real time, and remains ON.
Example 2
The Y output of DHSCS instruction is different from the general Y output.
1. When M0 is ON, the DHSCS instruction is executed. When the current value of HC200 changes from 99 to 100 or
from 101 to 100, Y0.10 outputs its state to the external output terminal immediately, and is not affected by the
program scan time.
2. When the current value of HC200 changes from 99 to100, the contact of HC200 is ON immediately. When SET
Y0.11 is executed, Y0.11 is still affected by the scan time, and outputs its state only after END is passed.
