Disturbance archive

In addition to the periodic archive, there is an independent disturbance archive. Contrary to the
periodic archive, the disturbance archive is filled only if the corrector is under fault conditions.
The following data is stored:
Archive index
Time stamp
Running number
14
Disturbance totalizer readings for V
The relevant statuses of the above totalizers
Overview of status (bit string)
Checksum for the data record (CRC)
The memory depth is 600 entries.

Daily archive

In the daily archive, the following values are stored at the end of a day (adjustable parameter, e.g.
06:00 o'clock):
Archive index
Time stamp
Running number
Totalizer readings for V
The relevant statuses of the above totalizers
Disturbance totalizer readings for V
The relevant statuses of the above totalizers
Mean values for pressure, temperature, K coefficient and C
The relevant statuses of the above measured values
Maximum periodic quantity of the day for V
Maximum periodic quantity of the day for V
Overview of status (bit string)
Checksum for the data record (CRC)
The daily record is written at the end of a gas day. When the daily record is written, the formation of
the mean and maximum values is initialized.
If the date is adjusted, two daily records are written: the first record with the old date and the sec-
ond record with the new date. The totalizer readings recorded, and the mean values are identical in
both records, while a zero (0) is entered for the maximum values in the second record.
Two daily records are also written if the clock is set beyond the turn of the gas day. Example: The
turn of the gas day is 6 o'clock and the clock is set from 5:58 to 6:07.
The memory depth is 731 entries.
