Section 14. PakBus Networking
14-15
Being a router requires more resources than being a leaf node. Allow as many
nodes as possible to be leaf-nodes and allow only routers to beacon.
If a CR800 is configured as a router (i.e., the IsRouter setting is set to “1” or
“True”) you can view its Routing Table using PakBus Graph. Right-click on
the graphic of the CR800 and select Show Settings. You may see something
like this:
There are three routes in the above routing table. The second route (4, 22, 22,
1000) is interpreted as follows:
4 CR800 Com port number 4 (CSDC 7) is active (see below).
22 PakBus address of Neighbor that routes toward destination
PBA.
22 Destination PakBus address.
1000 Hop Metric (message response time in milliseconds).
The CR800’s numbered Com ports are:
1. RS-232 Port
2. CS I/O Modem Enabled (ME)
3. CS I/O COM310 Modem
4. CS I/O CSDC 7
5. CS I/O CSDC 8
6. C1/C2
7. C3/C4
8. C5/C6
9. C7/C8
You can copy the CR800’s routing table using the Routes Instruction, into a
Public variable and view it in Numeric Display. The following figure shows
part of such a routing table describing the route to PakBus address 4094.
When field (2) and (3) contain the same address, this indicates that the CR800
is a neighbor to the destination device in field (3).
RoutingTable(1) – CR800 Com port used for communication (see numbered
Com ports above)
RoutingTable(2) – PakBus address of CR800’s neighbor leading to the device
in RoutingTable(3)
