Max. Records
Use this option to retain a specific number of records. When
the number of records exceeds this setting value, HMI will
delete the first record and insert the new record into the
last address. For example, if the setting value is set to 100
and the number of records in history exceeds 100, the first
record is deleted and the second record will become to the
third record, the third record will become to the forth
record…and the 100th record will become to 99th record.
The new record (101st record) becomes the 100th record.
