Low/High Range Alarms:
This number is a hex representation showing which data points are out of range. 0x01 shows
data point 1 in alarm state. 0x04 shows data point 3 in alarm state.
Data Points:
Data points are shown in the same order as the modbus device configuration display in the modbus/device list
page. Data is displayed in floating point form. When a specific point is unavailable (4A4P-M broken wire alarm) or the point
is not supported as part of the configuration (phase B current on a single phase H8163 meter hookup) the point will be
logged as blank. This preserves the column structure of the file, and allows notation of invalid data. SQL databases often
accept blank or NULL as a valid entry in a data table to represent invalid data.
For data exported from the BMO website, the columns that are invalid (NULL) are reported as blank fields. This makes it
easier to import into MS Excel as blank cells. With the current firmware, the AcquiSuite will report blank fileds rather than
"NULL" to make direct import of data from the AcquiSuite easier, as well as reduce the file size. Developers intending to
use data files from the AcquiSuite should handle both the word "NULL" as well as a blank column as indications of an
invalid data point.
Log Storage Capacity
The AcquiSuite uses approximately 8 Mbytes of flash disk for log file storage. As data from the modbus meters is collected,
