I have a site with three CR1000 data loggers, each connected to a central router via ethernet. One of these loggers includes a weather station, and I would like to access this data directly within the programming for the other data loggers.
I have not been able to find clear instruction on how to do this in the manual, and was not able to find anything in a search of this forum. Can someone give me an overview of what I would need to do, and point me in the right direction?
The dataloggers each need to be assigned unique Pakbus addresses.
In the Network Services settings on one datalogger, put the IP address of the other datalogger in the Pakbus TCP Client field.
You should then be able to use instructions like GetVariables(). You need to use -1 for the neighbor address, or use the Route() instruction to get a reference to the IP port.
The Pakbus TCP Client setting will make the datalogger open an IP connection to the other datalogger. It will keep that connection alive with a Pakbus message every 2 minutes.
