*1 This operation differs from the operation of CC-Link IE Field Network remote I/O module (with safety functions). For the system,
configure an external interlock circuit or an interlock circuit using a ladder program. Do not use a stop of safety remote I/O module as an
interlock condition.
For the operation of CC-Link IE Field Network remote I/O module (with safety functions), refer to the following.

3.3 Function List
Description
This function selects double wiring or single wiring of the input
wiring.
This function changes an input signal when a predetermined time
has passed after an actual input change.
A delay time can be set for each input change pattern, OFF to ON
or ON to OFF. In addition, the function prevents incorrect inputs
caused by noise since a pulse of a certain time length is not taken
in a module.
This function selects double wiring or single wiring of the output
wiring.
Description
This function discriminates failures by monitoring the discrepancy
state of doubled safety remote inputs (SA\X).
When the discrepancy state is detected, a minor error occurs. The
module will recover from the error by eliminating its cause.
This function outputs test pulses to turn off the external input
signals (X0 to XB) that are on for a short time and diagnoses
contacts including external devices for failure.
When failure is detected, a minor error occurs. The module will
recover from the error by eliminating its cause.
To use this function, settings of "Input mode setting" and "Input test
pulse setting" are required.
This function outputs test pulses to turn off the external output
signals (NZ2GFS12A2-16DTE: Y0 to Y3, NZ2GFS12A2-14DT: Y0
to Y1) that are on for a short time and diagnoses the internal circuit
for failure.
When failure is detected, a minor error occurs. The module will
recover from the error by eliminating its cause.
This function reads back output results and diagnoses whether the
external output signals (NZ2GFS12A2-16DTE: Y0 to Y3,
NZ2GFS12A2-14DT: Y0 to Y1) are correctly output.
When an incorrect output is detected, a minor error occurs. The
module will recover from the error by eliminating its cause.
