*D15 Routing Table Datalogger Memory Usage:
Per node in network
16 bytes
Per neighbor
8 bytes
Per router in network 2 x routers x (routers –1) bytes
For example:
Number of nodes = 4
CR10X-PB memory usage = 64 bytes
Number of neighbors = 3
CR10X-PB memory usage = 24 bytes
Number of routers = 2
CR10X-PB memory usage = 4 bytes
*D17 View Routing Table
*D17 01 :xxxx
PakBus Address of destination node
01 :yyyy
Packet sent via router with PakBus Address yyyy
01 :zzzz
The worst case response time between nodes in seconds
(Hop Metric)
02 :xxxx
PakBus Address of destination node
02 :yyyy
Packet sent via router with PakBus Address yyyy
02 :zzzz
The worst case response time between nodes in seconds
(Hop Metric)
0n :xxxx
PakBus Address of destination node
0n :yyyy
Packet sent via router with PakBus Address yyyy

If there is no router, only the neighbor is indicated in the *D17 routing table.
For example, if the device with PakBus address 3 is a neighbor to a datalogger,
the datalogger’s routing table will look like this:
01 :0003
PakBus Address of destination node
01 :1.0000 Worst case response time in seconds
The *D17 listing will change once the datalogger discovers a change in the
neighbor list that results in a change in the best routes to other nodes in the
network. *D17 shows the current best routes. It does not show all routes even
though the datalogger may have access to all possible routes to any given node.
If a router’s neighbor list changes, all routers are notified and will recalculate
their best route routing table based on the new information.
Although *D17 shows neighbors, in the case of multiple peripherals it does not
show the ports used to access the respective neighbors.
