Functions of Digital I/O Slave Units
Section 11-3
11-3-2 Input Filter (Input Units Only)
Description
An input value is read more than once during a set time interval. The input
value can be set to be enabled only when all the read values are the same.
This function operates for all input points in one Slave Unit.
Input Time Constant
When the input data turns ON, the input data is read 4 times at a set time (1/4
of the time setting). The internal input data turns ON only when all four values
are ON. The ON timing is delayed by the value of the input time constant. The
same function is supported when the input data turns OFF.
OFF Response Time
When the input data turns OFF, the input data is read 5 times at a set interval
(1/5 of the OFF response time setting). The internal input data turns OFF only
when all values are OFF. The OFF timing is delayed by the value of the OFF
response time.
This function can also be used to implement an OFF delay.
To enable reading pulses shorter than the communications cycle time, set the
OFF response time to a value longer than the communications cycle time.
(The input may remain ON if the input pulse interval is too short.)
