Meaning Diagnosis/Statistics Log Cycle Global/local Global
Function Specifies the interval to write the diagnostic and statistical information of the diagnosis/statistics log in units of
seconds.
When 0 is specified, the diagnostic and statistical information is written only once when the diagnosis/statistics
log is ended.
Note The write interval does not change even if you change the value of this system-defined variable while the
diagnosis/statistics log operation is in progress.

Variable name
_EC_StatisticsLogErr
*
Meaning Diagnosis/Statistics Log Error Global/local Global
Function TRUE when the diagnosis/statistics log failed to start or it is impossible to write into the log.
The value of this flag is determined when _EC_StatisticsLogBusy (Diagnosis/Statistics Log Busy) changes to
FALSE after the diagnosis/statistics log operation is started.
The error end is caused by the following.
• Another records cannot be added in the log file because the capacity of the SD Memory Card is fully used.
• The SD Memory Card is write protected.
• There is no SD Memory Card.
• The function cannot be started because the value specified for _EC_StatisticsLogCycleSec (Diagnosis/Statis-
tics Log Cycle) is invalid.
Data type BOOL Range of values TRUE or FALSE
