Displaying Structured Variable Values in Tables

Subsequent instructions describe an example of how an array of a structure is displayed in a table. To prepare, create the MyStruct DUT and the declarations in the PLC_PRG program.

TYPE MyStruct :
\ STRUCT
\ \ iNo : INT;
\ \ bOnStock : BOOL;
\ \ strPartNumber : STRING;
\ END_STRUCT
END_TYPE


PROGRAM PLC_PRG
VAR
\ arrStruct : ARRAY[0..6] OF MyStruct;
\ iSelectedColumn : INT;
END_VAR

1. Drag the Table visualization element to the visualization editor.

2. Assign the array variable arrStruct to the Data array property.

   ⇒

   The structure components are displayed as column headers and the array index is as row headings.

3. Change the property Columns ‣ Column ‣ [0] ‣ Column header to an informative header (example: Number).

4. Change the header of column [1] to in stock and column [2] to Part number. Adjust the column width.

5. Assign a color to the property Selection ‣ Selection color.

6. Define the property Selection ‣ Selection type as row selection.

7. Define the variable PLC_PRG.iSelectedColumn for the property Selection ‣ Variable for row selection.

   ⇒

   The following display results in online mode:
