A
RWw offset/size information (Address 19968 to 20207 (4E00H to 4EEFH))
The areas to store the RWw start number and number of points for each station number.
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 = 19968 + (station number -1)
× 2
• Size buffer memory address = 19969 + (station number -1) × 2
RWr offset/size information (Address 20224 to 20463 (4F00H to 4FEFH))
The areas to store the RWr start number and number of points for each station number.
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 = 20224 + (station number -1)
