Term. execution time
Time required to execute an instruction or group of instructions. If the
execution time of a program exceeds the Scan() Interval, the program is
executed less frequently than programmed and the Status table SkippedScan
(p. 487) register will increment.
Term. expression
A series of words, operators, or numbers that produce a value or result.
Term. FFT
Fast Fourier Transform. A technique for analyzing frequency-spectrum data.
Term. File Control
File Control is a feature of LoggerNet, PC400 and RTDAQ
(p. 95)
datalogger support software. It provides a view of the CR1000 file
system and a menu of file management commands:
Delete facilitates deletion of a specified file
Send facilitates transfer of a file (typically a CRBasic program file) from
PC memory to CR1000 memory.
Retrieve facilitates collection of files viewed in File Control. If
collecting a data file from a CF card with Retrieve, first stop the
CR1000 program or data corruption may result.
Format formats the selected CR1000 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 CR1000 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-data memory
The portion of CR1000 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. 526) by default, with new data
overwriting the oldest data.
Term. final-memory data
Data that resides in final-data memory.
