3.3 Function List
Description
Selects double wiring or single wiring of
the input wiring.
Reduces incorrect inputs caused by
noise of input signals.
Set the time taken from when an
external input turns on/off until when
the input signal is detected in the
module.
Selects double wiring or single wiring of
the output wiring.
Counts the total number of ON times of
each output point.
Discriminates failures by monitoring the
discrepancy state of doubled safety
remote inputs (SA\X).
Outputs test pulses to turn off the
external input signals (X0 to X1F) that
are on and diagnoses contacts
including external devices for failure.
Outputs test pulses to the input circuit
of the safety remote I/O module to
detect a circuit-fixing failure. The test
pulses turn off the external input signals
(X0 to X1F) that are on to detect the
failure.
Outputs test pulses to turn off the
external output signals (Y0 to Y7) that
are on and diagnoses the internal
circuit for failure.
Reads back output results and
diagnoses whether the external output
signals (Y0 to Y7) are correctly output.
Prevents effects due to overvoltage and
overcurrent from spreading to other
modules of the safety system.
Limits the users who can access the
CPU module or safety remote I/O
module.
Users can select whether to continue
safety communication or stop it when
an external power supply voltage error
occurs.
The functions of the safety extension
module or the standard extension
module are available when the
extension module is connected.
