7.2.4 Camera Files

JPEG images taken by a CC640 digital camera (retired) connected to the
datalogger can be stored to the CF card rather than CPU memory. This is done
by configuring the PakBus setting Files Manager for the datalogger. This can
be done using DevConfig or PakBus Graph.

Programming

7.3.1 The CardOut() Instruction

The CardOut() instruction is used to send data to a CF card. CardOut() must
be entered within each DataTable() declaration that is to store data to the CF
card. Data is stored to the card when a call is made to the data table.
CardOut(StopRing, Size)
Parameter Enter
Data Type
StopRing A code to specify if the data table on the CF card is fill-and-stop or ring (newest data
overwrites oldest).
Constant
Value
0
1
Size The size to make the data table. The number of data sets (records) for which to allocate
memory in the CF card. Each time a variable or interval trigger occurs, a line (or row) of
Constant
data is output with the number of values determined by the output instructions within the
table. This data is called a record.
Note
NL116 Ethernet and CompactFlash
Result
Ring
Fill and stop
Enter –1000 and the size of the table on the card will match the size of the
internal table on the datalogger. Enter any other negative number and all
remaining memory (after creating any fixed-size data tables) will be allocated to
the table or partitioned among all tables with a negative value for size. The
partitioning algorithm attempts to have the tables full at the same time.
