Link area allocation
• The link relays and link registers to be used in the PC(PLC) link are allocated in the link area of the
CPU unit. Link area allocations are specified by setting the system registers of the CPU unit.
Note:
The PC(PLC) link 1 is available for the FPΣ 32k type only.
Set the system register 46 to "Reverse" to use the PC(PLC) link 1.

Link area configuration
• Link areas consist of link relays and link registers, and are divided into areas for PC(PLC) link 0 and
PC(PLC) link 1 and used with those units.
• The link relay which can ben used in an area for either PC(PLC) link 0 or PC(PLC) link 1 is maximum
1024 points (64 words), and the link register is maximum 128 words.
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).
