14.5.3 Traffic Flow
Keep beacon intervals as long as possible with higher traffic (large numbers of
nodes and / or frequent data collection). Long beacon intervals minimize
collisions with other packets and resulting retries. The minimum recommended
beacon interval is 60 seconds. If communications traffic is high, consider setting
beacon intervals of several minutes. If data throughput needs are great,
maximize data bandwidth by creating some branch routers, and / or by
eliminating beacons altogether and setting up neighbor filters.
14.6 LoggerNet Device Map Configuration
As shown in
FIGURE. Flat Map
(p. 138) and
FIGURE. Tree Map
(p. 138), the
essential element of a PakBus® network device map in LoggerNet is the
PakBusPort. After adding the root port (COM, IP, etc), add a PakBusPort and
the dataloggers.
Figure 50: Flat Map
Figure 51: Tree Map
Use the 'tree' configuration when communications requires routers. The shape of
the map serves to disallow a direct LoggerNet connection to CR1000_2 and
CR200Series, and implies constrained routes that will probably be established
by user-installed neighbor filters in the routers. This assumes that LoggerNet
beacons are turned off. Otherwise, with a default address of 4094, LoggerNet
beacons will penetrate the neighbor filter of any in-range node.
