Appendix 2 List of Link Special Relay (SB)
Description
Stores the link-down status of the own station P1 side.
Off: Link-up
On: Link-down
The time until link-up starts after power-on or Ethernet cable connection may vary. Normally link-
up takes several seconds. Depending on device status on the line, link-up processing is
repeated and may increase the time.
(Also used in the CLPA conformance test.)
(Updated even if set as an error invalid station.)
(Updated even if set as a reserved station.)
Stores the status of reserved station specification by parameter. The station number of the
station set as a reserved station can be checked with 'Reserved station setting status' (SW00C0
to SW00C7).
Off: Not specified
On: Specified
Stores the status of error invalid station setting by parameter. The station number of the station
set as an error invalid station can be checked with 'Error invalid station setting status' (SW00D0
to SW00D7).
Off: Not specified
On: Specified
Stores the status of parameter reception from the master station.
Off: Reception complete
On: Reception not completed
Stores the setting status of "Data link faulty station setting" of the own station.
Off: Clear
On: Hold

Off: No setting
On: Set
For local stations, this relay stores the acceptance status of the IP address from the master
station.
Stores the data link status of each station.
Off: All stations normal
On: Faulty station exists
When this relay is turned on, the status of each station can be checked with 'Data link status of
each station' (SW00B0 to SW00B7).
Depending on the link refresh timing, the update of 'Data link status of each station' (SW00B0 to
SW00B7) may be offset by one sequence scan.
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.
(Conditions)
Reserved stations and stations that surpass the maximum station number are ignored.
Stores the data link status of the master station.
Off: Normal
On: Error
Stores whether a reserved station is set.
Off: No setting
On: Set
When this relay is turned on, the status of each station can be checked with 'Reserved station
setting status' (SW00C0 to SW00C7).
Depending on the refresh timing, the update of 'Reserved station setting status' (SW00C0 to
SW00C7) may be offset by one sequence scan.
Set whether an error invalid station is set.
Off: No setting
On: Set
When this relay is turned on, the status of each station can be checked with 'Error invalid station
setting status' (SW00D0 to SW00D7).
Depending on the refresh timing, the update of 'Error invalid station setting status' (SW00D0 to
SW00D7) may be offset by one sequence scan.
