Block guarantee of cyclic data per station

This function allows guaranteeing the consistency of the cyclic data for each device station according to the parameter
setting.
To ensure the consistency of data exceeding two words, use this function.
When this function is not used, cyclic data may be separated into new data and old data in 2-word (32-bit) units,
depending on the auto refresh timing.
Set this function to master stations, local stations and standby master stations.
The following example shows the range in which data of remote register RWw is secured when this function is set in
the remote net Ver.1 mode.

controller CPU
For device station number 1 that has setting of "4 stations occupied" in the remote net Ver.1 mode, remote register
data in the range RWw0 to RWwF are guaranteed.
Data are guaranteed in the same way for other remote devices (RX/RY/RWr).
They are also guaranteed for remote devices (RX/RY/RWr/RWw) in the remote I/O network mode.
