Appendix 2 Special Register List
APPENDICES
(10)A to Q/QnA conversion
ACPU special registers D9000 to D9255 correspond to Q/QnA special registers
SD1000 to SD1255 after A to Q/QnA conversion.
(However, the Basic model QCPU and Redundant CPU do not support A to Q/QnA
conversion.)
These special registers are all set by the system, and cannot be set by the user
program.
To set data by the user program, correct the program for use of the Q/QnACPU
special registers.
However, some of SD1200 to SD1255 (corresponding to D9200 to 9255 before
conversion) can be set by the user program if they could be set by the user program
before conversion.
For details on the ACPU special registers, refer to the user's manual for the
corresponding CPU, and MELSECNET or MELSECNET/B Data Link System
Reference Manuals.
Remark
Supplemental explanation on "Special Register for Modification" column
1. For the device numbers for which a special register for modification is specified,
modify it to the special register for QCPU/QnACPU.
2. For the device numbers for which is specified, special register after
conversion can be used.
3. Device numbers for which is specified do not function for QCPU/QnACPU.
