Appendix A. Glossary of Terms
Intermediate StorageDatalogger memory used to temporarily store values
(such as a running total and number of samples for an average calculation),
typically to be used for output calculations. The datalogger uses Intermediate
Storage to accumulate sensor readings until output.
L
Link Communications route between two devices, for example the phone
link between two phone modems.
LDEP Logger Data Export Protocol, a protocol and client application that
provides for data distribution from the communications server to a third party
application through a standard TCP/IP socket. Installed with LoggerNet
Admin; see the associated PDF file for more information. Requires record-
specific acknowledgements for record flow control. See LDMP.
LDMP Logger Data Monitoring Protocol, a protocol and client application
that provides for data distribution from the communications server to a third
party application through a standard TCP/IP socket. Installed with LoggerNet
Admin; see the associated PDF file for more information. Requires very
simple acknowledgements for record flow control. See LDEP.
Log FilesText files that are stored on the computers hard drive that record
activity. They contain information about communications between the
communications server and other devices in the datalogger network. Log files
are typically used for troubleshooting purposes. LoggerNet has four types of
log files: Transaction, Communications Status, Object State, and Low Level
I/O. Refer to Appendix E, Log Files, or the help within the LogTool (in PC400
click the Tools | LogTool menu item) application for information on these log
files.
M
MD9An MD9, or multi-drop modem, is a communications device that uses
twisted pair cable for connection. Typically, the system consists of one MD9
base modem that is attached to the users computer, with one or more remote
modems at the datalogger field site. One remote modem is needed for each
datalogger at the field site.
MeasurementsValues stored by the datalogger in an Input Location after
reading an electronic signal from a sensor and converting the raw signal into
meaningful units.
Mixed-array Dataloggers with mixed-array operating systems save output in
a common area of the dataloggers final storage memory. When data is
directed to final storage, a unique array ID number is stored, followed by other
values as determined by the datalogger program. These are called elements.
Mixed-array dataloggerstypically save all information that is directed to
output storage to the same area of datalogger memory (as opposed to table-
based dataloggers that always store different output processing intervals to
separate tables in datalogger memory). Data retrieved by the PC must be
processed by PC software to separate the data based on the array IDs.
