Block Structure

Variable Type	Name	Data Type	Description
VAR_INPUT	Execute	BOOL	Block enabling
	FILENAME#	STRING	Name of the recipe file
	INDEX	WORD UINT	Recipe index to be written
	SRC	STRUCT	Variable where the data is read
VAR_OUTPUT	Q	BOOL	End of operation
	ERROR	BOOL	Error occurrence flag
	ERRORID	BYTE USINT	Identifier of the occurred error
VAR	WRITERECIPE_INST_0	WRITERECIPE	Instance of access to block structure

Operation

When this block identifies a leading edge in Execute, it gets the data from SRC file and sends them to the recipe file selected by the INDEX index in the FILENAME#. If everything goes successfully, Q receives TRUE and remains so while Execute is TRUE.

NOTE!

Recipes stored in RAM is identified by 'RECIPE_NAME'. Recipes stored on the SD card are identified by 'RECIPE_NAME.CSV'.

If there is any error in the execution, the Error output is activated and ErrorID displays an error code according to the table below.

Code	Description
1	Incomplete recipe
2	Invalid structure
3	Nonexistent recipe
4	Invalid file
5	Invalid file or nonexistent SD card
6	SD card blocked for writing

Example in Ladder

WRITERECIPE_example01

The above example attempts to write the contents of SRC in the index 4 of the recipes file stored in SD card 'RECIPE_SD.CSV'. The block does not find the specified file, enabling the ERROR output with ERRORID with value 5 and disabling the Q output.

WRITERECIPE_example02

The above example attempts to write the contents of SRC in the index 4 of the recipes file stored in SD card 'RECIPE_SD.CSV'. The block finds the specified file, but does not find the index 4, enabling the ERROR output with ERRORID with value 3 and disabling the Q output.

WRITERECIPE_example03

The above example attempts to write the contents of SRC in the index 4 of the recipes file stored in SD card 'RECIPE_SD.CSV'. The block finds the file and the specified index, stores values in the recipe, disables the ERROR output and enables Q output.

Example in ST

The example below displays the instructions for applying the example above in the ST language.

VAR

SRC : STRUCT_RECIPE;

WRITERECIPE_INST_0 : FB_WriteRecipe;

END_VAR

WRITERECIPE_INST_0.Execute := DI1;

WRITERECIPE_INST_0(FILENAME:='RECIPE_SD.CSV', INDEX:=1, SRC:=SRC);

DO1 := WRITERECIPE_INST_0.Q;
