Leaf nodes are measurement devices at the end of a branch of the PakBus
®
web.
o Leaf nodes can be linked to any router.
o A leaf node cannot route packets but can originate or receive them.
Routers are measurement or telecommunications devices that route packets to
other linked routers or leaf nodes.
o Routers can be branch routers. Branch routers only know as neighbors
central routers, routers in route to central routers, and routers one level
outward in the network.
o Routers can be central routers. Central routers know the entire network.
A PC running LoggerNet is typically a central router.
o Routers can be router-capable dataloggers or communications devices.
The CR3000 is a leaf node by factory default. It can be configured as a router by
setting IsRouter in its Status table to 1 or True. The network shown in figure
PakBus Network Addressing
(p. 357) contains six routers and eight leaf nodes.
8.5.2.1 Router and Leaf-Node Configuration
Consult the appendix Router and Leaf-Node Hardware for a table of available
PakBus® leaf-node and router devices.
Figure 111: PakBus network addressing
LoggerNet is configured by default as a router and can route datalogger- to-
datalogger communications.
