Section 11. Glossary
Term: support software
See datalogger support software
(p. 494).
Term: swept frequency
A succession of frequencies from lowest to highest used as the method of
wire excitation with VSPECT
(p. 521) measurements.
Term: synchronous
The transmission of data between a transmitting and a receiving device
occurs as a series of zeros and ones. For the data to be "read" correctly, the
receiving device must begin reading at the proper point in the series. In
synchronous communication, this coordination is accomplished by
synchronizing the transmitting and receiving devices to a common clock
signal (see asynchronous
(p. 281)).
Term: system time
When time functions are run outside the Scan() / NextScan construct, the
time registered by the instruction will be based on the system clock, which
has a 10 ms resolution. See scan time
(p. 513).
Term: table
Final-storage 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.
Term: task
Two definitions:
o Grouping of CRBasic program instructions automatically by the
CR800 compiler. Tasks include measurement, SDM or digital, and
processing. Tasks are prioritized when the CRBasic program runs
in pipeline mode.
o A user-customized function defined through LoggerNet Task
Master.
Term: TCP/IP
Transmission Control Protocol / Internet Protocol.
