Appendix 2.2 List of link special registers (SWs)
The data link status can be checked by the word information (link special registers: SWs).
When the standby master station is controlling the data link, availability is basically
identical to that of the master station.
When the standby master station is operating as a local station, availability is identical
to that of a local station.
