Description
"RecipeImport_DB"(
req:=_bool_in_,
done=>_bool_out_,
busy=>_bool_out_,
error=>_bool_out_,
status=>_word_out_,
Recipe_DB:=_variant_inout_);
The "RecipeImport" instruction
imports recipe data from a CSV file,
in CPU load memory, to a recipe
data block referenced by the
RECIPE_DB parameter. Start values
in the recipe data block are
overwritten by the import process.
The import operation is triggered by
the "REQ" parameter. The BUSY
parameter is set to "1" during import
processing. After the execution of
RecipeImport stops, BUSY is reset
to "0" and the completion of the
operation is indicated with "1" at the
DONE parameter. If an error occurs
during execution, then parameters
ERROR and STATUS indicate the
result.
