*1: If the input signal exceeds the hardware input limit, the module only shows the maximum value. If the input
signal is below the lower limit, it only shows the minimum value. And an error flag will be set.
*2: If the input signal exceeds the hardware input limit, it also exceeds the conversion limit and a conversion
limit error appears. For example in the voltage input mode (4 mA to 20 mA), when the input signal is 0 mA,
exceeding the hardware upper limit, it also exceeds the conversion upper limit. The module uses the upper
limit value (-384) as the input signal and a conversion limit error appears.
*3: If an input signal exceeds the absolute range, it might damage the channel.
