*1: The input signal should NOT exceed the limit. If exceeding the limit, damage may occur.
*2: 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. If the input signal exceeds the hardware input limit, it also
exceeds the digital conversion limit and a conversion limit error appears. For example in the current input mode (4 mA to
20 mA), when the input signal is 0 mA, exceeding the hardware lower limit, it also exceeds the conversion lower limit.
The module uses the lower limit value (-48) as the input signal. If a disconnected analysis is required, you can check if
the digital conversion value is -48.
*3: The conversion time is the time for each channel to convert signals to hardware input signals. If you need to calculate
a complete conversion time, you need to add the PLC scan time.
*4: Use the program to read the values in SR to obtain the corresponding A/D conversion value for the channel.
