7.3.7 Settings archive
Archive capacity: An average of 500 records (depends on length/type of
records)
The settings archive stores changes of parameters, especially if they have
effect on metrological features of the device. The archive also stores the identification
of the employee who performed the change. The record contains a time mark,
employee identification, description of his/her activity, and eventually the new and old
values of the parameters which were changed.
This archive, similarly as the event archive and unlike the other archives, does
not rewind, i.e. after filling the archive up, one can not add to it and other changes of
parameters are disabled. This archive can not be displayed on the display, and the
content can only be displayed using a PC.
7.3.8 Billing archive (*)
Archive capacity: 15 records
Device contains billing archive. This archive serves as data recorder with billing
period setup at device parameters. There are two possible ways how to write into
this archive – one time writing according to preset time or periodically at intervals
1,2,3,4,6 or 12 months. At this time new record of all actual counters like primary
volume and base volume is created including both total counter and single tariffs.
Billing period is configurable and crossing time as well..
7.3.9 Gas composition archive (*)
Archive capacity: 150 records
When gas composition or compressibility calculation method are changed new
record is stored into this archive. The record contains time and date stamp, previous
used compressibility method and value of gas composition items. If this archive is full
the oldest data records are overwritten. Notice: in old FW version changes of gas
composition are recorded in setup archive.
7.4 Device parameterization
7.4.1 Parameterization using service SW
The device provides a wide range of options regarding its settings. Due to the
wide range, the parameterization is performed in a full scope using the supplied
service SW [22] designed for PCs. Besides the device settings, this SW also allows
the read out, display, archiving, and printing of the instantaneous values as well as
the archive contents. Description of the parameterization using the SW is in [19].
7.4.2 Parameterization from the device keypad
The device allows the setting of some of the selected parameters directly from
the device keypad, i.e. without using a computer. These parameters are:
•
Service parameters: station name, gas hour
•
Communication settings: Name of station, communication protocol, transfer
speed, network address, network address 2
