Currently a client has been implemented to do Modbus TCP requests. All functions codes for Modbus TCP/IP are supported. U can use the client like this:
umodbus.client.tcp.send_message
umodbus.client.tcp.parse_response_adu
umodbus.client.tcp.read_coils
umodbus.client.tcp.read_discrete_inputs
umodbus.client.tcp.read_holding_registers
umodbus.client.tcp.read_input_registers
umodbus.client.tcp.write_single_coil
umodbus.client.tcp.write_single_register
umodbus.client.tcp.write_multiple_coils
umodbus.client.tcp.write_multiple_registers
