■Link special register (SW) (Un\G18464 to Un\G18975)
The SW value is stored.
RX offset/size information
■RX offset/size information (Un\G19456 to Un\G19697)
The start number and the number of points of RX for each station are stored.
The offset and size of buffer memory areas for each station number (other than a station number 0) can be calculated using
the following formulas:
• Offset buffer memory address = 19456 + (station No. - 1) 2
• Size buffer memory address = 19457 + (station No. - 1) 2
RY offset/size information
■RY offset/size information (Un\G19712 to Un\G19953)
The start number and the number of points of RY for each station are stored.
The offset and size of buffer memory areas for each station number (other than a station number 0) can be calculated using
the following formulas:
• Offset buffer memory address = 19712 + (station No. - 1) 2
• Size buffer memory address = 19713 + (station No. - 1) 2
