Behavior when HMI Space is Insufficient

• Stop Saving Operation Log: No more data is saved,

and no archiving is done.

• Synchronize to External Device: The data is

archived to the SD or USB device. If previous data

exists on the SD/USB device, the new data is

merged with the existing data. If there is sufficient

storage space in the HMI, half of the data in the

log is erased to make room for more data. If there

is insufficient storage space in the HMI, all of the

data in the log is erased.

exist, old data is erased from the log to make

room for new data.
