In the link special register, the data linking information is stored as numeric values.
Thus, faulty areas and causes of errors can be checked using or monitoring the link
special registers in the sequence programs.
Moreover, the link special register (SW) that stores the link status is used for the
detailed information of the network diagnostics of GX Developer. For a list of the device
numbers for each display item, see Section 8.1, "Network Diagnostics (Line Monitor)."
When multiple network modules are installed, the SW of each network module is
refreshed to the corresponding SW of the CPU module if each network module's
refresh parameters are not set. If the refresh parameters are set for at least one network
module, the refresh parameters of all the network modules should be reviewed.
