APPENDICES
(9) A to QnA conversion
ACPU special registers D9000 to D9255 correspond to QnA special registers SD1000
to SD1255 after 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 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.
