DataLogCreate
1
creates and initializes a
data log file stored in the \DataLogs
directory of the CPU. The data log file is
created with a pre-determined fixed size.
"DataLogNewFile_DB"(
req:=_bool_in_,
records=:_udint_in_,
done=>_bool_out_,
busy=>_bool_out_,
error=>_bool_out_,
status=>_word_out_,
name=:_DataLog_out_,
ID:=_dword_inout_);
DataLogNewFile
1
allows your program to
create a new data log file based upon an
existing data log file. A new data log will be
created and implicitly opened based with
the specified NAME. The header record will
be duplicated from the original data log
along with the original data log properties.
The original data log file will be implicitly
closed.
1
The DataLogCreate and DataLogNewFile operations extend over many program scan cycles. The actual time required
for the log file creation depends on the record structure and number of records. Before the new data log can be used for
other data log operations, your program logic must monitor the transition of the DONE bit to TRUE.
