field
Data tables are made up of records and fields. Each row in a table represents a record and
each column represents a field. The number of fields in a record is determined by the
number and configuration of output processing instructions that are included as part of the
DataTable() declaration.
File Control
File Control is a feature of LoggerNet, PC400, Device Configuration Utility, and RTDAQ data
logger support software. It provides a view of the data logger file system and a menu of file
management commands.
fill and stop memory
A memory configuration for data tables forcing a data table to stop accepting data when
full.
final-data memory
The portion of memory allocated for storing data tables. Once data is written to final-data
memory, it cannot be changed but only overwritten when it becomes the oldest data. Final-
data memory is configured as ring memory by default, with new data overwriting the oldest
data.
final-storage data
Data that resides in final-data memory.
Flash
A type of memory media that does not require battery backup. Flash memory, however, has
a lifetime based on the number of writes to it. The more frequently data is written, the
shorter the life expectancy.
FLOAT
Four-byte floating-point data type. Default data logger data type for Public or Dim variables.
Same format as IEEE4.
