Modbus TCP/IP - climate thermostat

Hi All,
I tried to integrate HASS with soft PLC based on Codesys 3.5.
I would like to create interface in HASS for my automation system. I would like to use Modbus TCP/IP to send and receive data from PLC.
I managed to test modbus connection using “switch”, “sensor” form hass example .
I have problem with termostat for modbus communication. I am able to receive current temperature, current setpoint (in case of changeing register by e.g server) but I cannot send setpoint to my modbus server. My example is listed below.

climate:

• platform: modbus
  scan_interval: 5
  name: termostat salon
  hub: hub1
  slave: 1
  data_type: uint //i’ve tried int - doesnt work
  data_count: 1
  scale: 1
  offset: 0
  precision: 1
  max_temp: 30
  min_temp: 15
  temp_step: 1
  target_temp_register: 15 // holding register 15
  current_temp_register: 16 // holding register 16

Anyone has similiar issue?
