How the Program Editor Shows Entry Errors in FBD (GS 4.9)

Red text indicates illegal syntax.

Note: When you replace the illegal address value or symbol with a valid value, the font automatically changes to the default font color (black, unless you have customized the window).

A red wavy line underneath a value indicates that the value is either out of range or incorrect for this type of instruction.

A green wavy line underneath a value indicates that the variable or symbol being used has not been defined. STEP 7-Micro/WIN 32 permits you to write your program before defining variables and symbols. At any time, you can add the value to your Local Variable Table or Symbol Table.

Tips:

·Click the right mouse button to bring up a menu with the five closest matches for global symbols.

·Use the Define Symbol dialog box to resolve undefined symbols.
