ROC800L
The ROC800L firmware provides many of the same capabilities as the
ROC800 firmware. We recommend, however, that the ROC800L
supports only six gas runs (using a single AGA key). History stored in
firmware is limited to measurements from gas meter runs, rather than
liquids. Software supports most liquid-related capabilities; other
firmware functions remain the same.
1.5.1 Historical Database and Event & Alarm Log
The historical database provides archiving of measured and calculated
values for either on-demand viewing or saving to a file. It provides an
historical record in accordance with API Chapter 21.1. You can
configure each of up to 240 points in the historical database to archive
values under various schemes, such as averaging or accumulating, as
appropriate for the type of database point.
The historical database is maintained in 13 segments (0-12). You can
configure each segment in the database to archive selected points at
specified time intervals. The segments can continuously archive or can
be turned on and off.
Note: Configure gas meter history in segments 1-12, where a segment
number corresponds to a station number (meter history for
station 1 in segment 1, and so on). This allows configuration
changes to trigger archive records in accordance with API 2.1
guidelines.
You can distribute history points among history segments 1 through 12
and the general history segment. For each history segment, you can
configure the number of periodic history values archived, the frequency
of archiving periodic values, the number of daily values archived, and
the contract hour. The number of minute values is fixed at 60. The 240
points provide a total of over 224,000 entries (equal to more than 35
days of 24-hour data for 240 points).
The Event Log records the last 450 parameter changes, power on and
off cycles, calibration information, and other system events. The event
