3.7.2 Sending a Program to the CR200
The compiled datalogger program is sent to the CR200 with the File Download
transaction. The FileName parameter of this transaction describes the file
name and location in datalogger memory where the datalogger program should
be stored. The compiled datalogger program will always have an extension of
“.bin”. An example of the FileName parameter is “CPU:CR200Program.bin”.
In addition, the attributes of the file should be specified. With the CR200 the
only file attribute to consider when sending the datalogger program is run now
since the compact size of the datalogger disallows the storage of old programs
or files.
The compact buffer size of the CR200 requires that the application not send a
packet that exceeds 100 bytes including the header. If the datalogger program
being sent exceeds this maximum size, the message must be broken across
multiple packets. The complexity of sending a program to the datalogger is
shown in the following diagram.
