Appendix 2
This section describes the buffer memory of the master/local module.
Appendix 2.1
This buffer memory stores the RX, RY, RWw, and RWr values.
(1) Remote input (RX) (Un\G0 to Un\G1023)
This buffer memory stores the RX value. The RX start number and number of points for each station No. can be
checked by the RX offset/size information (Un\G19456 to Un\G19695). (

(2) Remote output (RY) (Un\G1024 to Un\G2047)
This buffer memory stores the RY value. The RY start number and number of points for each station No. can be
checked by the RY offset/size information (Un\G19712 to Un\G19951). (

(3) Remote register (RWw) (Un\G2048 to Un\G10239)
This buffer memory stores the RWw value. The RWw start number and number of points for each station No. can
be checked by the RWw/offset size information (Un\G19968 to Un\G20207). (
