Term: CVI
Communication verification interval. The interval at which a PakBus®
device verifies the accessibility of neighbors in its neighbor list. If a neighbor
does not communicate for a period of time equal to 2.5 times the CVI, the
device will send up to four Hello s. If no response is received, the neighbor is
removed from the neighbor list. See the section
PakBus — Overview
(p. 87)
for more information.
Term: data cache
The data cache is a set of binary files kept on the hard disk of the computer
running the datalogger support software
(p. 579).
A binary file is created for
each table in each datalogger. These files mimic the storage areas in
datalogger memory, and by default are two times the size of the datalogger
storage area. When the software collects data from a CR6, the data are
stored in the binary file for that CR6. Various software functions retrieve
data from the data cache instead of the CR6 directly. This allows the
simultaneous sharing of data among software functions.
Similar in function to a CR6 final-storage data tables, the binary files for the
data cache are set up by default as ring memory
(p. 598).
