Description
Stores the self-loopback test normal completion or abnormal completion status.
• OFF: Normal completion
• ON: Abnormal completion
(Conditions)
This is enabled when Self-loopback test completion status (SB0092) is ON.
Stores the loop test completion status.
• OFF: Not executed or execution in progress
• ON: Completed
If completed, the completion status can be checked by Loop test normal/abnormal
end (SB0095).
Stores the loop test normal completion or abnormal completion status.
• OFF: Normal completion
• ON: Abnormal completion
(Conditions)
This is enabled when Loop test completion status (SB0094) is ON.
Stores the match or mismatch status of the actual network configuration and the
network map of the CC-Link IE Field Network diagnostics.
• OFF: Match
• ON: Mismatch
After return or addition of the slave station, SB0098 may be turned ON regardless of
the actual match/mismatch status.
Stores whether the number of slave stations (including a submaster station)
connected is 120 or less, or 121 or more.
• OFF: 120 or less
• ON: 121 or more
Number of connected modules is the total of the slave stations (including a submaster
station) which are currently connected and the disconnected stations (slave stations
which were previously connected).
Stores the loop test request accept status.
• OFF: Loop test not accepted
• ON: Loop test accepted
The master station is turned ON during loop test mode.
The slave stations are turned ON during the loop test and turned OFF when the loop
test is completed.
Stores the baton pass status for each station.
• OFF: All stations normal
• ON: Faulty station found
If a faulty station is found, the status of each station can be checked by Baton pass
status (each station) (SW00A0 to SW00A7).
Depending on the timing of the link refresh, the update of Baton pass status (each
station) (SW00A0 to SW00A7) may be offset by one sequence scan.
(Conditions)
• This is enabled when the Baton pass status (own station) (SB0047) is OFF.
• Reserved stations and stations higher than the maximum station number are
ignored.
Stores the baton pass status for master station.
• OFF: Normal
• ON: Error
(Conditions)
This is enabled when the Baton pass status (own station) (SB0047) is OFF.
Stores the cyclic transmission status for each station.
• OFF: Cyclic transmission for all stations in progress
• ON: Cyclic transmission not executed for some stations
If cyclic transmission are not executed for some stations, the status of each station
can be checked by Data link status (each station) (SW00B0 to SW00B7).
Depending on the timing of the link refresh, the update of Data link status (each
station) (SW00B0 to SW00B7) may be offset by one sequence scan.
(Conditions)
• This is enabled when the Baton pass status (own station) (SB0047) is OFF.
• Reserved stations and stations higher than the maximum station number are
ignored.
