Process operation data will be deleted when the calendar clock of the DL30-G has been advanced or reversed
by 24 hours or more due to time correction/adjustment, etc., or when the DL30-G has stopped for 24 hours or
more due to power failure.
In case of time correction or power failure within 24 hours, the chart will be affected as shown below.

becomes invalid. DL30-G records data again from the new current time.
When the new current time is ahead of the beginning of the chart, the whole chart becomes invalid.
Reverse current time
NOTES
• When the calendar clock has been reversed by less than 24 hours, the DL30-G records
data for the overlapped time period twice. Therefore, the chart represents data for less
than 48 hours until next 48 hours has passed.
Advance current time
Delete
Blank
When the current time has been advanced by less than 24 hours or
when time has passed less than 24 hours during power failure,
the data for the advanced/passed time is left blank (missing data) and
DL30-G records data from the new current time.
If a part of data deviates from the chart range because of the advanced
current time, the part of data is deleted from the oldest.
8.2.13 Maximum number of characters used in DL30GCFG
The description in this manual is based on the assumption that double-byte and single-byte characters are
mixed in the settings of the DL30GCFG.
User can use twice as many number of characters if they are all single-byte ASCII codes.
