Remote net Ver.2 mode
The remote net Ver.2 mode is selected when a system is configured with the master station and Ver.2-compatible slave
stations or when Ver.2-compatible slave stations will be added to the system in future.
In this mode, more points can be used than in the remote net Ver.1 mode.

*1 The last two bits in RX and RY cannot be used for communications between the master station and a local station.
*2 In the master station and a local station, 0 points are assigned to RWr and RWw in a remote I/O station. (RWr and RWw move over
forward.)
Note that buffer memory areas for RWr and RWw in a local station do not move over when the local station is in the remote net Ver.1
mode.
*3 When a local station is in the remote net Ver.1 mode, data are stored in the Ver.1-compatible area. When a local station is in the remote
net Ver.2 mode, data are stored in the Ver.2-compatible area.
