(4) Slave station offset, size information
In the remote net Ver.2 mode and remote net additional mode, the assignment of RX/RY/RWw/RWr for each
station differs depending on the expanded cyclic setting and the remote I/O station points setting.
(a) Offset
This area stores the start buffer memory addresses of RX/RY/RWw/RWr assigned for each station.
When two or more stations are occupied, a value is stored only in the start buffer memory address of the first
station.
For example, when the station number 1 occupies two stations, values are stored only in the RX/RY/RWw/RWr
offset, size information of the station number 1 and those for the station number 2 remain the default.
(b) Size
This area stores the sizes of RX/RY/RWw/RWr assigned for each station (unit: word).
When the size is less than one word, the storage value is rounded up; therefore, 1 is stored.
When eight points are set in the remote I/O station points setting, 1 is stored. For the remote I/O station points
setting, refer to Page 170, Section 8.3.9.
If the target station is a reserved station, 0000
The following table lists the relationship between RX/RY/RWw/RWr offset, size information and buffer memory
