Appendix 2 Details of Buffer Memory Addresses
Offset/size information
The areas to store the device start number and number of points for each station number.
RX offset/size information (Address 19456 to 19695 (4C00H to 4CEFH))
The areas to store the RX start number and number of points for each station No.
The offset and size of buffer memory address for each station number (other than a station number 0) can be calculated using
the following formulas:
• Offset buffer memory address = 19456 + (station number -1)
× 2
• Size buffer memory address = 19457 + (station number -1) × 2
RY offset/size information (Address 19712 to 19951 (4D00H to 4DEFH))
The areas to store the RY start number and number of points for each station No.
The offset and size of buffer memory address for each station number (other than a station number 0) can be calculated using
the following formulas:
• Offset buffer memory address = 19712 + (station number -1)

• Size buffer memory address = 19713 + (station number -1)
