(4) Slave station offset, size information
In the remote net ver.2 mode or remote net additional mode, the assignment of
RX/RY/RWw/RWr for the station numbers varies according to the expanded
cyclic setting and remote I/O station points setting.
(a) Offset
Stores the head buffer memory address of RX/RY/RWw/RWr assigned to
each station.
When 2 or more stations are occupied, values are stored into only the head
buffer memory address of the station number. (When station No. 1
occupies 2 stations, values are stored into the RX/RY/RWw/RWr offset and
size of station No. 1, and the RX/RY/RWw/RWr offset and size of station
No. 2 remains default.)
(b) Size
Stores the size of RX/RY/RWw/RWr assigned to each station in word unit.
When the size is less than 1 word, it is rounded up and 1 is stored. (When
the remote I/O station points setting is 8 points, 1 is stored.)
Refer to Section 8.3.9 for the remote I/O station points setting method.
For the reserved station, 0000
The following table lists the correspondence between station numbers and the
