APPENDICES
(9) A to QnA conversion correspondences
Special relays SM1000 to SM1255 are the relays which correspond to ACPU special
relays M9000 to M9255 after A to QnA conversion.
These special relays are all set by the system, and cannot be set by the user
program.
To turn them ON/OFF by the user program, change the special relays in the program
into those of QnACPU.
However, some of SM1084 and SM1200 to SM1255 (corresponding to M9084 and
M9200 to M9255 before conversion) can be turned ON/OFF by the user program, if
they could be turned ON/OFF by the user program before conversion.For details on
the ACPU special relays, see the user's manuals for the individual CPUs, and
MELSECNET or MELSECNET/B Data Link System Reference Manuals
The following are additional explanations about the Special Relay for Modification
column.
When a special relay for modification is provided, the device number should
be changed to the provided QnACPU special relay.
When is provided, the converted special relay can be used for the device
number.
When is provided, the device number does not work with QnACPU.

M9000 SM1000 – Fuse blown
OFF : Normal
ON : Module with blown
fuse
• Turned on when there is one or more output modules of
which fuse has been blown.
• Remains ON if the condition is restored to normal
thereafter.
• Output modules of remote I/O stations are also checked
fore fuse condition.
QnA

I/O module verify
error
OFF : Normal
ON : Error
• Turned on if the status of I/O module is different form
entered status when power is turned on.
• Remains ON if the condition is restored to normal
thereafter.
• I/O module verification is done also to remote I/O station
modules.
• Reset is enabled only when special registers SD1116 to
SD1123 are reset.
QnA

the installed AJ71PT32 (S3) modules.
• Remains ON if the condition is restored to normal
thereafter.
QnA
M9005 SM1005 ––
AC DOWN
detection
OFF : AC DOWN not
detected
ON : AC DOWN detected
• Turns ON if an instantaneous power failure of within 20ms
occurs during use of the AC power supply module.
• Reset when the power supply is switched OFF, then ON.
QnA
• Turns ON if an instantaneous power failure of within 1ms
occurs during use of the DC power supply module.
• Reset when the power supply is switched OFF, then ON.
QnA
M9006 SM1006 – Battery low
OFF : Normal
ON : Battery low

thereafter.
QnA
M9007 SM1007 – Battery low latch
OFF : Normal
