Appendix 4 List of Link Special Relay (SB)
*1 This register is enabled when 'Data link status of own station' (SB0049) is off.
SB0110 CPU minor error status of
each station
For local stations, stores the minor error occurrence status of the
CPU module on each station.
For remote stations, stores the minor error occurrence status of
each station.
Off: All stations normal or station with a moderate/major error exists.
On: Station with a minor error exists.
When this relay is turned on, the status of each station can be
checked with 'CPU minor error status of each station' (SW0110 to
SW0117).
Depending on the refresh timing, the update of 'CPU minor error
status of each station' (SW0110 to SW00117) 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: Normal, or a moderate or serious error
occurring" is reflected to the CC-Link IE TSN Class A remote station.
