5.3 Defining unused inputs/outputs
All unused inputs and outputs must be given the board slot value 0 and the value 1 also for the ter-
minal number. The value 0.1 is also the default value for most of the functions. However, if you want
to use the values of a digital input signal for e.g. testing purposes only, you can set the board slot
value to 0 and the terminal number to any number between 2…10 to place the input to a TRUE state.
In other words, the value 1 corresponds to 'open contact' and values 2 to 10 to 'closed contact'.
In case of analogue inputs, giving the value 1 for the terminal number corresponds to 0% signal
level, value 2 corresponds to 20%, value 3 to 30% and so on. Giving value 10 for the terminal number
corresponds to 100% signal level.
