Section 11. Glossary
432
Format formats the selected CR800 memory device. All files, including
data, on the device will be erased.
LNCMD software
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.
Fill and Stop Memory
A memory configuration for data tables forcing a data table to stop
accepting data when full.
final storage
The portion of CR800 SRAM Memory allocated for storing data tables
with output arrays. Final Storage is a ring memory, with new data
overwriting the oldest data.
FLOAT
Four ‐ byte floating ‐ point data type. Default CR800 data type for Public
or Dim variables. Same format as IEEE4. IEEE4 is the name used when
declaring data type for stored data table data.
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.
FTP
File Transfer Protocol. A TCP/IP application protocol.
full duplex
Systems allow communications simultaneously in both directions.
garbage
The refuse of the data communication world. When data are sent or
received incorrectly (there are numerous reasons why this happens), a
string of invalid, meaningless characters (garbage) often results. Two
common causes are: 1) a baud ‐ rate mismatch and 2) synchronous data
being sent to an asynchronous device and vice
versa.
