Operation or function
Others
*1 It is executed when the trigger logging data collection is completed or data collection for the specified number of storage files is
completed.
Operation of when the data logging function is used
If data is backed up during execution of the data logging function and the function has been set to be started automatically
when the operating status of the CPU module is changed to RUN, the data logging function will be automatically executed
when the status of the CPU module changes to RUN after the restoration processing. To restart the data logging function after
the restoration processing without the above setting, use the CPU module logging configuration tool.
When the CPU built-in memory (function memory) is specified for the data storage destination memory, the function memory
is not backed up. Therefore, when the data logging is restarted after the restoration processing, the logging files are deleted
after the CPU module is powered off or the RESET state is cleared, and the logging file number starts from 1 at the storage
file switching.
Restoration during execution of the restoration processing
The restoration processing triggered by turning on SM1354 cannot be executed during execution of the restoration
processing. (The latter restoration processing is ignored.)
When the CPU module database access function is used
When the data is backed up with the CPU module data backup/restoration function and restored by turning on SM1354 while
using the CPU module database access function, power off and on or reset the CPU module regardless of the completion
status of the restoration. (For the automatic restoration by SD955, the CPU module is not required to be powered off and on or
reset.)
