50 Range of link relays used 64 64 64 64
52 Starting No. of word for link relay transmission 64 84 104 64
53 Link relay transmission size 20 20 24 0
Note) No. 50 (range of link relays used) must be set to the same range for all the units.

No. Name
51 Range of link registers used 128 128 128 128
54 Starting No. for link register transmission 128 128 208 128
55 Link register transmission size 40 40 48 0
Note) No. 51 (range of link registers used) must be set to the same range for all the units.
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).

Communication Unit Technical Manual ARCT1F396E>.
