Appendix F. CR510PB w/ P193 Master

to CR205s Network

In this configuration LoggerNet does 15 minute scheduled collections of a

remote CR510PB running a P193 to transfer variable values from 5 remote

CR205s (may be other rf CR200 Series). This approach results in the lowest

remote average current drain because the remotes originate the data transfer

and their RF400 Series radios are off the rest of the time.

The P193 instruction has all the CR205s’ addresses and does device discovery.

A single P193 can communicate with many remotes having sequential PakBus

addresses.

There is no beaconing in the described configuration. LoggerNet needs no

beacon as it can discover CR510PB using the static route created from its

device map. When LoggerNet is first run, it will be unaware of the CR510PB,

but at the first connection they will exchange hellos and neighbor lists and

become neighbors. LoggerNet can thereafter communicate with any node in

the network. LoggerNet will keep the CR510PB as a neighbor until LoggerNet

is closed or its router reset.

The example programs that follow demonstrate the ability of the P193

instruction to send data to a remote and receive data back from the remote.

In order for LoggerNet to send a program to a CR205 in the

network, it may be necessary to temporarily set the

CR510PB_100’s P193 execution interval (program execution

interval) to 3 minutes or more during the program transfer so that

CR205 time-slot transmissions do not prevent the program

transfer.

Be sure to collect CR510PB_100 data beforehand.
