Description
Stores if a receive frame error line status caution level is currently occurring in the P2 side of the own station.
Off: A receive frame error line status caution level is not occurring.
On: A receive frame error line status caution level is occurring.
Stores if a receive frame error line status caution level has occurred in the P2 side of the own station from
power-on until the present.
Off: A receive frame error line status caution level has not yet occurred.
On: A receive frame error line status caution level has occurred.
Stores the setting status of link scan mode.
Off: Asynchronous with sequence scan or constant link scan
On: Synchronous with sequence scan
Stores the status of reserved station specification by parameter. The station No. 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 No. 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 setting status of "Network Topology" in "Basic Settings" for the own station (master operating
station).
Off: Line topology, star topology, or coexistence of star and line topologies
On: Ring topology
Stores the setting status of "Data Link Error Station Setting" under "I/O Maintenance Settings" in
"Supplementary Cyclic Settings" of "Application Settings" for the own station.
Off: Clear
On: Hold
Stores the setting status of "Output Hold/Clear Setting during CPU STOP" under "I/O Maintenance Settings"
in "Supplementary Cyclic Settings" of "Application Settings" for the own station.
Off: Hold
On: Clear
Stores the status of the IP address setting by parameter.
Off: No setting
On: Set
For local stations, this relay stores the acceptance status of the IP address from the master station.
Stores if a receive frame error line status warning level is currently occurring in the P2 side of the own
station.
Off: A receive frame error line status warning level is not occurring.
On: A receive frame error line status warning level is occurring.
Stores if a receive frame error line status warning level has occurred in the P2 side of the own station from
power-on until the present.
Off: A receive frame error line status warning level has not yet occurred.
On: A receive frame error line status warning level has occurred.
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 baton pass 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 "Baton pass status of each
station" (SW00A0 to SW00A7).
Depending on the link refresh timing, the update of "Baton pass status of each station" (SW00A0 to
SW00A7) may be offset by one sequence scan.
(Conditions)
• This relay is enabled when "Baton pass status of own station" (SB0047) is off.
• When "Baton pass status of own station" (SB0047) is turned on, data prior to error is held.
• Reserved stations and stations higher than the maximum station No. are ignored.
