Bit pattern
indicating where
battery voltage
drop occurred
• All corresponding bits go 1(ON) when battery voltage drops.
• Subsequently, these remain 1(ON) even after battery voltage has been
returned to normal.
• In the alarm, data can be held within the time specified for battery low.
• The error indicates the complete discharge of the battery.
• When the High Performance model QCPU, Process CPU, Redundant
CPU or Universal model QCPU is used, the corresponding bits always
remain OFF since the memory card B is a standard memory.

SD52 Battery low
Bit pattern
indicating where
battery voltage
drop occurred
• Same configuration as SD51 above
• After the alarm is detected (ON), the alarm turns OFF by error detection
(ON). (For the Universal model QCPU only)
• Turns to 0 (OFF) when the battery voltage returns to normal thereafter.
• When the High Performance model QCPU, Process CPU, Redundant
CPU or Universal model QCPU is used, the corresponding bits always
remain OFF since the memory card B is a standard memory.
S (Error) New

AC/DC DOWN

Number of times
for AC/DC DOWN
detection
• Every time the input voltage falls to or below 85% (AC power)/65% (DC
power) of the rating during operation of the CPU module, the value is
incremented by 1 and stored in BIN code.
• The counter repeats increment and decrement of the value ;

the mounted MINI(-S3) turns ON, the bit of the corresponding station turns to 1 (ON).
2) Turns to 1 (ON) when communication between the mounted MINI(-S3) and CPU module
cannot be made.
