(9)A to Q/QnA conversion correspondences
ACPU special registers D9000 to D9255 correspond to the special registers SD1000 to SD1255 after
These special registers are all set by the system, and users cannot use them to set program data.
Users who need to set data with these registers should edit the special registers for the Q/QnA.
However, before conversion users could set data at special registers D9200 to D9255 only, and after conversion users can also set data at registers 1200 to 1255.
For more detailed information concerning the contents of the ACPU special registers, see the individual CPU users manual, and the MELSECNET and MELSECNET/B data link system reference manual.
REMARK
Supplemental explanation on "Special Register for Modification" column
1For the device numbers for which a special register for modification is specified, modify it to the special register for QCPU/QnACPU.
2For the device numbers for which 
is specified, special register after conversion can be used.
3Device numbers for which 
is specified do not function for QCPU/QnACPU.
