Functions of E3NW-ECT
Digital I/O Slave Units have the following convenient functions, in addition to the I/O signal processing.
Purpose
This function prevents data changes and unstable data, which may be caused by fluctuation of input
data and unstable contact state due to chattering and noise. This function is available in Free Run
Mode.
Details of functions
This function reads inputs (ON/OFF) within a certain set time and turn ON the inputs if they are all
same (all ON or all OFF)
,
and turn them OFF if not.
Note that this function works for all inputs of Slave Units and Expansion Units at the same time.
When the input shifts from OFF to ON (or ON to OFF), it is read 4 times from that point at an interval
of 1/4 of the set time. When all read results are ON (or OFF), the input is turned ON (or OFF).
The input filter is set through SDO communications.
The applicable index is 3002 hex.
Refer to the applicable index (Input Filter in Free-Run Mode) in "A-1 Object Dictionary" on page A-2 for
the set values.
