Data stored Details
Off: Not used This relay switches to on if the detailed
On: In use information n exists when SM0 switched to
on.
Off: Power-on/normal • This relay turns on when one or more of
power supply voltage the power supply modules whose power
On: Power-off/voltage drop has been shut off or power supply voltage
detected/power supply has dropped (not including a momentary
module not mounted 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.
Off: Not detected/power- • This relay turns on when one or more
off/no power supply power supply module failures have been
module detected on the redundant power supply
On: Detected 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.
Off: Not detected • This relay turns on when a momentary
On: Detected 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.
Off: Valid/power-off/no • This relay turns on when one or more of
power supply module invalid power supply modules have been
On: Invalid 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.
