SM80
Detailed information 1: Flag
in use
Off: Not used
On: In use
This relay switches to on if the detailed
information n exists when SM0 switched to
on.
S (Status change)
ALL
SM112
Detailed information 2: Flag
in use
ALL
SM150
Power-off/power supply
voltage drop detection
Off: Power-on/normal
power supply voltage
On: Power-off/voltage drop
detected/power supply
module not mounted
• This relay turns on when one or more of
the power supply modules whose power
has been shut off or power supply voltage
has dropped (not including a momentary
power failure), or one or more of empty
slots for the power supply module are
detected on the redundant power supply
base unit.
• This relay turns on if causes to turn on
any bits of SD150 have been occurred.
• This relay turns off if causes to turn on
any bits of SD150 have been removed.
• In a multiple CPU system, the flags are
stored only to the CPU No.1.
S (Status change)
Rn
RnP
RnPSF
SM151
Power supply module
failure detection
Off: Not detected/power-
off/no power supply
module
On: Detected
• This relay turns on when one or more
power supply module failures have been
detected on the redundant power supply
base unit.
• This relay turns on if causes to turn on
any bits of SD151 have been occurred.
• This relay turns off if causes to turn on
any bits of SD151 have been removed.
• In a multiple CPU system, the flags are
stored only to the CPU No.1.
S (Status change)
Rn
RnP
RnPSF
SM152
Momentary power failure
detection (power supply
module 1)
Off: Not detected
On: Detected
• This relay turns on when a momentary
power failure of the input power supply to
the power supply 1 or 2 is detected one or
more times. After turning on, this relay
remains on even if the power supply
recovers from the momentary power
failure.
• This relay turns off the flags (SM152 and
SM153) of the power supply 1 and 2
when the CPU module starts up.
• When one of the two power supply
modules is powered off, this relay turns off
the corresponding flag to one powered
off.
• In a multiple CPU system, the flags are
stored only to the CPU No.1.
S (Status change)

SM154
Invalid power supply
module
Off: Valid/power-off/no
power supply module
On: Invalid
• This relay turns on when one or more of
invalid power supply modules have been
detected on the redundant power supply
base unit.
• This relay turns on if a factor to turn on
any bits of SD154 have been occurred.
• This relay turns off if all the factors to turn
on any bits of SD154 have been removed.
• In a multiple CPU system, the flags are
stored only to the CPU No.1.
