device number
Fixed signals FXDSIGN - -
The Fixed signals function (FXDSIGN) generates a number of pre-set (fixed) signals
that can be used in the configuration of an IED, either for forcing the unused inputs in
other function blocks to a certain level/value, or for creating certain logic.
14.4.1 Principle of operation
There are eight 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
