7.7.2 Link Area Allocation

To use the PLC link function, link areas need to be allocated. Set the allocations for both the
link relays and link registers using the system registers of the CPU.
Link areas consist of link relays and link registers and are divided into areas for PLC link 0
and PLC link 1. A maximum of 1024 link relays (points) and 128 link registers (words) can be
used in the PLC link areas.
