When link areas are allocated as shown above, the No.1 send area can be sent to the No.2, No.3 and
No.4 receive areas. Also, the No.1 receive area can receive data from the No.2 and No.3 send areas.
No.4 is allocated as a receive area only, and can receive data from No.1, No.2 and No.3, but cannot
transmit it to other stations.
Note:
The PC link 1 can be used to connect with the second PC link W0 of the FP2 Multi Communication Unit
(MCU). At that time, the link relay number and link register number for the PC link can be the same
values as the FP2 (from WL64, from LD128).
