ISPSoft User Manual

ISPSoft User Manual
does not support the symbols whose data types are STRING.
Users not only have to pay attention to the data formats in symbol tables, but also have to pay
attention to the comments on the symbols in a symbol table.
A CSV file can be opened in Microsoft Excel and Notepad, as shown below. In a CSV file, the cells
are divided by the commas. As a result, if there are commas in the Identifier Comment… cell for a
symbol in a symbol table, the system will automatically regard the contents after the first comma as
the contents of other cells, as shown by C2 and C3 which are in the red circle below. After the
symbol table is imported again, the contents after the first comma will be lost.
• Before the symbol table is exported
• After the symbol table is imported
6.2.9 Arranging the symbols
In the local symbol table in a function block, the order in which the symbols of the VAR_INPUT class,
the symbols of the VAR_IN_OUT class, and the symbols of the VAR_OUTPUT class are arranged
affects the order in which the operands in the function block are arranged. If users want to arrange
the symbols in the local symbol table in a function block, they can click a symbol which will be
moved upward or moved downward, and press Alt+ or Alt+ on the keyboard.
