In the typeFR, a 2 Mbyte memory area is managed consecutively for each slot,
and these are called common memory areas. The common memory area
corresponds to slot numbers 0 to 63.
Station Global is a user area for data sharing with other slots (functions)
managed for each slot. This offset and size are different depending on the slot
type.
In the typeFR with virtualization support, the slot numbers corresponding to PLC
is 1, Windows is 3. A part of the common memory area is shown in the following
figure. In the figure, Station Offset indicates the absolute address in the common
memory area, and Slot Offset indicates the relative address in the 2 Mbyte area
