Operation of PLC link
Turning on a link relay contact in one PLC turns on the same link relay in all other PLCs on the same
network.
Likewise, if the contents of a link register in one PLC are changed, the values of the same link register
are changed in all PLCs on the same network.

Link relay L0 for unit no.1 is turned on. The status change is fed back to the programs of the other units,
and Y0 of the other units is set to TRUE.
Link register
A constant of 100 is written to link register LD0 of unit no.1.
The contents of LD0 in the other units are also changed to a constant of 100.
