Example
Python
# output contacts: No. 1=OFF, No. 2=OFF, No. 3=ON, and No. 4=ON
res = get_digital_outputs(bit_list=[1,2,3,4])
#res 기대값 = 0b1100 (binary number), 12 (decimal number), or 0x0C (hexadecimal number)
# output contacts: No. 5=ON, No. 6=ON, No. 7=OFF, and No. 8=ON
res = get_digital_outputs([5,6,7,8])
#res 기대값 = 0b1011 (binary number), 11 (decimal number), or 0x0B (hexadecimal number)
