Retrieve
facilitates collection of files viewed in
File Control
. If
collecting a data file from a memory card with Retrieve , first stop
the CR800 program or data corruption may result.
Format formats the selected CR800 memory device. All files,
including data, on the device will be erased.
Term: File Retrieval tab
A feature of LoggerNet Setup Screen . In the Setup Screen network map
(Entire Network), click on a CR800 datalogger node. The File Retieval tab
should be one of several tabs presented at the right of the screen.
Term: fill and stop memory
A memory configuration for data tables forcing a data table to stop accepting
data when full.
Term: final-storage memory
The portion of CR800 SRAM memory allocated for storing data tables with
output arrays. Once data are written to final-data memory, they cannot be
changed but only overwritten when they become the oldest data. Final-data
memory is configured as ring memory
(p. 512)
by default, with new data
overwriting the oldest data.
Term: final-storage data
Data that resides in final-data memory.
Term: 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 are written, the shorter the life expectancy.
Term: FLOAT
Four-byte floating-point data type. Default CR800 data type for Public or
Dim variables. Same format as IEEE4.
Term: FP2
Two-byte floating-point data type. Default CR800 data type for stored data.
While IEEE four-byte floating point is used for variables and internal
calculations, FP2 is adequate for most stored data. FP2 provides three or four
significant digits of resolution, and requires half the memory as IEEE4.
