Appendix 2 Details of Buffer Memory Addresses
This section describes the buffer memory of the master/local module.
Appendix 2.1 Link device area (buffer memory address: 0 to
18975 (0
H
to 4A1F
H
))
This buffer memory stores the RX, RY, RWw, and RWr values.
(1) Remote input (buffer memory address: 0 to 1023 (0
H
to 3EF
H
))
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 (buffer memory address: 19456 to 19695 (4C00
H
to 4CEF
H
).
( Page 269, Appendix 2.2)
(2) Remote output (RY) (buffer memory address: 1024 to 2047 (400
H
to 7FF
H
))
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 (buffer memory address: 19712 to 19951 (4D00
H
to 4DEF
H
)).
