Function Details
This function reads inputs (ON or OFF) during a set time. When all readings are the same (all readings
are ON or all readings are OFF), this function turns ON or OFF the input value.
When an input changes from OFF to ON (or from ON to OFF), this function starts reading the input
from the moment four times at an interval of a quarter of the set time. When all readings are ON (or
OFF), this function turns ON (or OFF) the input value.

You can set the read time to the following: 0 ms, 0.5 ms, 1 ms (factory setting), 2 ms, 4 ms, 8 ms, 16
ms, 32 ms, 64 ms, or 128 ms.
Using this function causes a delay of the set time in turning ON (or OFF) contacts (ON delay time).
The ON delay time is represented by input response time (time required to read input) + input filter
time.
