If the value of the port number is ≥ 101, the connection is made through PakBus/TCP, either by
the CR1000 executing a TCPOpen() instruction or by having a connection made to the
PakBus/TCP CR1000 service.
via neighbor adr
Specifies address of neighbor / router to be used to send messages for this
route. If the route is for a neighbor, this value is the same as the address.
pakbus adr
For a router, specifies the address the route reaches. If a leaf node, this is 0.
response time
For a router, specifies time in milliseconds that is allowed for the route. If a
leaf node, this is 0.
8.5.9 Neighbors
Settings Editor name: Neighbors Allowed xxx
Array of integers indicating PakBus neighbors for comumunication ports:
RS-232, ME, SDC7, SDC8, SDC10, SDC11
Com1 (C1,C2)
Com2 (C3,C4)
Com3 (C5,C6)
Com4 (C7,C8)
This setting specifies, for a given port, the explicit list of PakBus node addresses
that the CR1000 will accept as neighbors. If the list is empty (the default
condition), any node is accepted as a neighbor. This setting will not affect the
acceptance of a neighbor if that neighbor address is greater than 3999. The formal
syntax for this setting follows:
neighbor := { "(" range-begin "," range-end ")" }.
range-begin := pakbus-address. ;
range-end := pakbus-address.
pakbus-address := number. ; 0 < number < 4000
If more than 10 neighbors are in the allowed list and the beacon interval is 0, the
beacon interval is changed to 60 seconds and beaconing is used for neighbor
discovery instead of directed hello requests that consume communication
memory.
8.5.10 PakBus Encryption
Two PakBus devices can exchange encrypted commands and data. Encryption
uses the AES-128 algorithm. Routers and other leaf nodes do not need to be set
for encryption. The CR1000 has a setting accessed through DevConfig
(p. 111) that
sets it to send and receive only encrypted commands and data. LoggerNet
(p. 655),
likewise, has a setting attached to the specific station that enables it to send and
406
