Appendix 5 List of Link Special Register (SW)
Description
Stores the data link status of each station.
0: Data link normally operating station
1: Data link faulty station
• If multiple stations change from faulty to normal, because they are reconnected
to the network one by one per cycle, the time until the status changes to "0:
Data link normally operating station" may vary by several seconds.
• If no response is received for several cycles, the station is determined to be a
data link faulty station.
• Since a local station cannot obtain the station information of the CC-Link IE
TSN Class A remote station when communicating in multicast mode, "0: Data
link normally operating station" is reflected to the CC-Link IE TSN Class A
remote station.
