Section 4. The CR1000 Type Datalogger
4-11
4.11 Collecting Files from the Datalogger
The CR1000 type datalogger can store files in memory for future use or
retrieval. The list of files contained in datalogger memory can be obtained by
requesting a file name of “.DIR” with the File Upload transaction. The
datalogger responds with a list of files that are stored on the datalogger. After
obtaining the directory listing of files that exist on the datalogger, use the File
Upload transaction to retrieve a specific file from the datalogger.
4.12 Controlling Packet Size
In order to stay within the maximum allowed packet size for the PakBus
protocol, an application must not request packets from the datalogger that
exceed the 1000 byte message size limit. The requested number of bytes from
the datalogger should always be less than this maximum size including the
header information in order to stay within the limits of the datalogger and
PakBus message limit.
