Special relays SM1000 to SM1255 are the relays which correspond to ACPU special
relays M9000 to M9255 after A to Q/QnA conversion.
(However, the Basic model QCPU and Redundant CPU do not support A to Q/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 QCPU/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 processing time may be longer when converted special relays are used with
the High Performance model QCPU and Process CPU. Uncheck "A-series CPU
compatibility setting" within the PC system setting in GX Developer parameters
when converted special relays are not used.
The following are additional explanations about the Special Relay for Modification
column.
1. When a special relay for modification is provided, the device number should
be changed to the provided QCPU/QnACPU special relay.
2. When is provided, the converted special relay can be used for the device
number.
3. When is provided, the device number does not work with QCPU/QnACPU.

Name Meaning
OFF : Normal
Fuse blown ON : Module with blown
fuse
I/O module OFF : Normal
verification error ON : Error
OFF : Normal
NIMI link error
ON : Error
Details
• 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.
• 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.
• Goes ON if MINI (S3) link error is detected at even one of
the installed AJ71PT32 (S3) modules.
• Remains ON if the condition is restored to normal
thereafter.
