*With regard to the errors related to the input signals’ exceeding the range of inputs which can be received by the
hardware and the conversion values’ exceeding the limits, whether the error code generated is within the range between
16#A000 and 16#A00F, within the range between 16#A400 and 16#A40F, or within the range between
16#A800~16#A80F depends on the LED indicator status defined by users.
