Cause
Data link of the own station was started.
Data link of another station was started.
Data link of the own station has been started in accordance
with the data link restart instruction.
Data link of the own station has been stopped in accordance
with the data link stop instruction.
Temporary error invalid station setting was executed.
Station number information shows the target station by the bit
pattern in units of 16 stations. (The setting can be
simultaneously executed for multiple stations.)
For station No.1, b0 of the station number information (1 to
16) is turned on. For station No.64, b15 of the station number
information (49 to 64) is turned on.
Temporary error invalid station cancel setting was executed.
Station number information shows the target station by the bit
pattern in units of 16 stations. (The setting can be
simultaneously executed for multiple stations.)
For station No.1, b0 of the station number information (1 to
16) is turned on. For station No.64, b15 of the station number
information (49 to 64) is turned on.
The master station duplication error cancel instruction was
executed
The number of retries clear was executed.
Master station was down, or manual switching of the master
and standby master station has occurred.
Refresh was started after standby master station switching.
Data link of the own station was stopped.
Data link of another station was stopped.
A WDT error has occurred in another station.
A fuse blown error has occurred in another station.
While data link was being performed, the station number
switch or transmission speed switch was changed.
Station number overlap of the slave station has occurred.
Station number information (1 to 4) shows the overlapped
station number by the bit pattern in units of 16 stations. (The
overlap may be simultaneously occurred in multiple stations.)
For station No.2, b1 of the station number information 1 is
turned on. For station No.64, b15 of the station number
information 4 is turned on.
For loading and parameter consistency status, any of the
following cases has occurred.
• The station types do not match.
• The number of occupied stations does not match.
• The extended cyclic settings do not match.
• The CC-Link compatible versions do not match.
Station number information (1 to 4) shows the station number
where an inconsistency has occurred by the bit pattern in
units of 16 stations. (The inconsistency may be
simultaneously occurred in multiple stations.)
For station No.1, b0 of the station number information 1 is
turned on. For station No.64, b15 of the station number
information 4 is turned on.
The parameter setting was changed.
