User Forum A 24/7 resource for Campbell Scientific users

Hello. I would appreciate some clarification concerning the support of SendData() and SendVariables() in CR200X.

According to the user manual:

3.1.7.1 PakBus
Other PakBus dataloggers can be used as "sensors" to consolidate all data
into one CR200(X).

10.9 Peer-to-Peer PakBus Communications
...
SendData
Sends the most recent record from a data table to a remote PakBus device.

Nevertheless, in CRBasic Editor 3.4 help:

Note: Other datalogger types which support this instruction can SendData to another datalogger. The CR200 and CR200X support sending data to a LoggerNet server only.

Also, in CR200X FAQ:

Is it possible to have a datalogger initiate the data transfer, rather than LoggerNet?
A datalogger can be programmed to initiate data transfer by using the SendVariables() or ModemCallback() instruction in CRBasic.

But in CRBasic Editor 3.4 help the SendVariables() function doesn't even appear.

Any help would be most welcome

The CR200X has a more limited feature set in its operating system than other dataloggers. I think the help files are correct. Here is my understanding:

• SendData works only for sending data to a LoggerNet server. LoggerNet is a "remote PakBus device" with a default PakBus address of 4094, so technically that part of the manual is correct.
• SendVariables and ModemCallback are not supported in the CR200X operating system.
• SendGetData is supported, but the other datalogger that is being contacted cannot be a CR200X. It has to be a CR1000, CR6, etc.

I'll see if someone can edit the information in the FAQ, since it is not relevant to the CR200X.

Best,

Dana, thanks for your response.

Best regards
