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:
Therea is no area for PC(PLC) link 1 with FP
Σ
. Even when using the PC(PLC) link1 at MCU side, the link
relays and link registers No. to be used at FP
Σ
side are WL0 to WL63 and LD0 to LD127.
