from modicon import Modicon
m = Modicon()

result = m.read_register_value('OUT_POZITIE_MV3_1') # register name as parameter
print(result)

Reading specific bit state:

from modicon import Modicon
m = Modicon()

result = m.get_bit_state('TENSIUNE_UPS') # bit name as parameter
print(result)

Reading all bit states from all registers:

from modicon import Modicon
m = Modicon()
result = m.get_all_bits_state()
print(result)
