Section 14. PakBus Networking
14-29
Transaction
An exchange of packets between nodes. An example is
the hello-exchange. Most packets come in
command/response pairs.
Tree Map
LoggerNet, Setup device map where succeeding
PakBus devices are added as children of the device
above. Along with appropriate neighbor filters a tree
map can force a certain route to a destination PakBus
device.
Verification
Interval
Equivalent to “communication verification interval.”
The setting that a PakBus device uses to determine
when it’s time (since the last communication) to send a
hello message to confirm that a neighbor can still
respond (and remain a neighbor). Verification intervals
are passed in hello-exchanges.
Verify Interval
xxx
Same as Verify xxx. A CR800 port’s setting for the
datalogger’s communication verification interval.
For a more in-depth treatment of PakBus packets and communications,
“PakBus Networking Guide” is available in pdf format at
