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

is recorded along with a date and time stamp. The Alarm Log records

the last 450 configured occurrences of alarms (set and clear). You can
