System registers

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