10.2.14 Link special register (SW)
Link special registers are used to store data on the communication status and errors
of an intelligent function module such as CC-Link IE controller network module and
MELSECNET/H network module.
Because the data link information is stored as numeric data, the link special registers
serve as a tool for identifying the locations and causes of faults.
The number of link special register points is as described in Table10.9.
