Meaning
• When fuse blown modules are detected, the lowest I/O module No. is stored
in D9000.
• 1 is added to the stored value each time the input voltage becomes 85[%]
(AC power supply/65[%] DC power supply) or less of the rating while the
CPU module is performing an operation, and the value is stored in BIN
code.
• When error is found as a result of self-diagnosis, error No. is stored in BIN
code.
• Refer to "19.4 Multiple CPU Error Codes" of the "Q173CPU(N)/Q172CPU(N)
Motion Controller (SV13/SV22) Programming Manual (Motion SFC) " for
details of the error code.
• The age (A.D, the rightmost two digits) when data on D9008 are updated,
and the month stored with a BCD code two digits.

Year(0 to 99) Month(1 to 12)
• The day when data on D9008 are updated, and the hour stored with a BCD
code two digits.

Day(1 to 31) Hour(0 to 23)
• The minute when data on D9008 are updated, and the second stored with a
BCD code two digits.

Minute(0 to 59) Second(0 to 59)
• The classification code to judge the error information stored in the error
information (D9014) is stored.
• The following codes are stored.
0: None
1: Module No./CPU No./Base No.
2: Parameter No.
• Error information to comply with the diagnostic error (D9008) is stored.
There are following two types information to be stored.
1) Module No./CPU No./Base No.
• Module No. or CPU No. is stored according to the error which occurred
in the case of the Multiple CPU system.
(Refer to each error code which is stored.)
CPU No.1: 1, CPU No.2: 2, CPU No.3: 3, CPU No.4: 4
2) Parameter No.
• The operation states of CPU as shown below are stored in D9015.
B15
1) Operating state of CPU
2) STOP cause
Note: Priority is earliest first
• Main cycle is stored in the unit 1ms.
• Setting range (0 to 65535[ms])
• The maximum value of the main cycle is stored in the unit 1ms.
• Setting range (0 to 65535[ms])
• Stores the year (2 lower digits) and month in BCD.
