This parameter changes the logic polarity for digital inputs and digital outputs, but not the enable input, the relay output or the 24V output.
When this parameter is zero digital outputs are in push-pull mode. When this parameter is one either the high-side drive (negative logic polarity) or the
low-side driver (positive logic polarity) is disabled. This allows outputs to be connected in a wire-ORed configuration.
