There are nine outputs from FXDSIGN function block:
• OFF is a boolean signal, fixed to OFF (boolean 0) value
• ON is a boolean signal, fixed to ON (boolean 1) value
• INTZERO is an integer number, fixed to integer value 0
• INTONE is an integer number, fixed to integer value 1
• INTALONE is an integer value FFFF (hex)
• REALZERO is a floating point real number, fixed to 0.0 value
• STRNULL is a string, fixed to an empty string (null) value
