Bit formulas are mathematical variables which only possess a logical low or high state. As opposed to float formulas with Boolean processing, the raw value is already predefined (0,1).
Entering Bit formulas:
Only Boolean operators are available for calculations (see chapter Boolean algebra.)
The mathematics driver also allows to define values (e.g. multi-bit) bitwise via Boolean formulas. For this, the desired bit-pattern has to be entered in the bit formula decimally after the operator (e.g. Bit0 and Bit1 ->3).
