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 FPΣ. Even when using the PC(PLC) link1 at MCU side, the link
relays and link registers No. to be used at FPΣ side are WL0 to WL63 and LD0 to LD127.
FP2: WL65 ⇔ WL1 : FPΣ
LD200 ⇔ LD136
