Description
"RecipeImport_DB"(
req:=_bool_in_,
done=>_bool_out_,
busy=>_bool_out_,
error=>_bool_out_,
status=>_word_out_,
Reci-
pe_DB:=_variant_inout_);
The "RecipeImport" instruction im-
ports 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 comple-
tion 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.
