Free buffer
space
This register stores free buffer space (unit: 1K byte).
If the value is small, processing overflow may occur.
For trigger logging, this register stores the buffer size until
when data are collected by the number of records after
trigger.
This register is cleared to "0" by a stop command from the
CPU Module Logging Configuration Tool.

overflow
occurred
This register stores the number of times that data logging
processing overflow occurred.
If an overflow occurs, some data may not be collected.
When the storage value reaches to 65535, count is resumed
from "0".
If Stop is specified for Operation occurring when number of
saved files is exceeded, processing overflow may occur
from when data collection by the number of specified
storage files is completed and until when data logging is
stopped.
This register is cleared to "0" by the registration of the
setting or a stop command from CPU Module Logging
Configuration Tool.
