Description

The structure ST_CsvTable is used to pass the buffer provided by the application to the corresponding function block.

Structure Elements

Name	Data type	Description
pbyTable	POINTER TO BYTE	Pointer to the buffer (two-dimensional ARRAY of type STRING) provided by the application.
uiNumOfRows	UINT	Specifies the number of rows (records) in the table.
uiNumOfColumns	UINT	Specifies the number of values per row (record) in the table.
udiSizeOfTable	UDINT	Specifies the total size in bytes of the table.

NOTE: To prevent access violation eventually caused by pointer access to the memory, use the arithmetic operator SIZEOF in conjunction with the targeted buffer to determine the value for udiSizeOfTable.

Example

The example shows how to assign the values to this structure:

PROGRAM POU
VAR
    g_asCsvTable:ARRAY[0..c_uiNumOfRows-1,0..c_uiNumOfColumns-1] OF
STRING(c_uiLengthOfValue);
        stCsvTable: FFU.ST_CsvTable;
END_VAR
VAR CONSTANT
        c_uiNumOfRows :UINT:= 100;
        c_uiNumOfColumns :UINT:= 10;
        c_uiLengthOfValue :UINT:= 40;
END_VAR
stCsvTable.pbyTable := ADR(g_asCsvTable);
stCsvTable.uiNumOfRows := c_uiNumOfRows;
stCsvTable.uiNumOfColumns := c_uiNumOfColumns;
stCsvTable.udiSizeOfTable := SIZEOF(g_asCsvTable);
