Explanation
• Stores error number that performs error reset
• All corresponding bits go 1(ON) when battery voltage drops.
• Subsequently, these remain 1(ON) even after battery voltage has been
returned to normal.

: This does not apply to Basic model QCPU.
• 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.
• 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.
• 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 ;

1) When any of X(n+0)/X(n+20), X(n+6)/X(n+26), X(n+7)/X(n+27) and X(n+8)/X(n+28) of
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.

• Value stored here is the lowest station I/O number of the module with the blown fuse.
• The lowest I/O number of the module where the I/O module verification number took place.
