data logger support software
LoggerNet, RTDAQ, PC400, and PC200W - these Campbell Scientific software applic-
ations include at least the following functions: data logger communications, down-
loading programs, clock setting, and retrieval of measurement data.
data output interval
The interval between each write of a record to a final-storage memory data table.
data output processing instructions
CRBasic instructions that process data values for eventual output to final-data memory.
Examples of output-processing instructions include Totalize(), Maximize(), Minimize(),
and Average(). Data sources for these instructions are values or strings in variable
memory. The results of intermediate calculations are stored in data output processing
memory to await the output trigger. The ultimate destination of data generated by data
output processing instructions is usually final-storage memory, but the CRBasic program
can be written to divert to variable memory by the CRBasic program for further pro-
cessing. The transfer of processed summaries to final-data memory takes place when the
Trigger argument in the DataTable() instruction is set to True.
data output processing memory
SRAM memory automatically allocated for intermediate calculations performed by
CRBasic data output processing instructions. Data output processing memory cannot be
monitored.
data point
A data value which is sent to final-data memory as the result of a data-output processing
instruction. Data points output at the same time make up a record in a data table.
data table
A concept that describes how data is organized in memory, or in files that result from col-
lecting data in memory. The fundamental data table is created by the CRBasic program as
a result of the DataTable() instruction and resides in binary form in main-memory SRAM.
The data table structure also resides in the data cache, in discrete data files on data log-
