Note that the processing time will increase when the converted special relay is used.
[How to read the Special Relay for Modification column]
• If the special relay number for QCPU or LCPU is provided, correct the program using it.
•  means that the converted special relay can be used.
•  means that the special relay cannot be used in QCPU or LCPU.

Meaning
• This relay turns on if there is at least one
output module whose fuse has blown.
• This relay remains on even after the
system returns to normal.
fuse
• Output modules on remote I/O stations
are also checked.
• This relay turns on if the status of the I/O
module differs from that registered at
power-on.
• This relay remains on even after the
system returns to normal.
• I/O modules on remote I/O stations are
also checked.
• This relay is reset only when SD1116 to
SD1123 are reset.
• This relay turns on if a momentary power
failure within 20ms occurs during use of
an AC power supply module.
• This relay is reset when the CPU module
is powered off and then on.
• This relay turns on if a momentary power
failure within 10ms occurs when using an
detected AC power supply module.
• This relay is reset when the CPU module
is powered off and then on.
• This relay turns on if a momentary power
failure within 10ms occurs during use of
a DC power supply module.
• This relay is reset when the CPU module
is powered off and then on.
• This relay turns on when the battery
voltage drops to or below the specified.
• It turns off when the battery voltage
returns to normal.
• This relay turns on when the battery
voltage drops to or below the specified.
• This relay remains on even after the
battery voltage returns to normal.
This relay turns on if an error is detected by
self-diagnostics.
• This relay turns on when the OUT F or
SET F instruction is executed.
detected
• It turns off when the SD1124 value is
cleared to zero.
