Table4.1 List of common functions for input/output modules
Function
Checks whether I/O signals are normal.
Hardware
Checks whether the safety remote I/O module
diagnostic
operates normally.
function
Power supply
Checks whether an overvoltage or undervoltage
diagnostic
occurs to the power supply which is input.
function
CC-Link
Checks whether the CC-Link Safety system
diagnostic
operates normally.
function
Avoids the effects of overvoltage and overcurrent
to other modules of the safety-related system.
Saves the error description saved inside the safety
remote I/O module to the inside nonvolatile
memory as an error history.
Sends the saved error history to the safety CPU
module.

Set the time between an external input turning ON/
OFF and the X input signal inside the module
turning ON/OFF.
Turns OFF the send data of a corresponding input
signal without stopping the module when a double
input discrepancy error is detected.
Sets the input parameters.
