2. Modules Ethernet+RS485Modules RS485 Modules Extension Modules
5 Types Expansion Modules
Digital Modules
Analog Modules
Temperature & Humidity Modules
Functional Modules
Communication Modules

3. Expansion Modules connection modes
Haiwell Modules-2 kinds of connection modes
Modules can be directly hung behind the host PLC to achieve expansion, with the parallel port connection.
Single host PLC can be expanded up to 7 modules in maximum (of which up to 3 communication modules)

4. Expansion Modules connection modes
As remote modules, Haiwell modules exchange data with host PLC by 485 network communication mode to achieve expansion, with the communication line connection.
One communication port can be expanded with multiple modules

5. DT-Digital Temperature & Humidity Modules
Haiwell digital temperature & humidity modules have 2 kinds of models: H04DT、H32DT，they can be used as expansion modules for any host PLC.
The H32DT temperature expansion module with RS485 communication port, can be used as a remote IO module; H04DT can measure temperature and humidity.

6. H04DT-Temperature & Humidity Module
H04DT module supports 4-channel DS18B20 temperature sensor、RW1820 temperature sensor、DS1990
sensor and SHT1X/SHT7X temperature-humidity sensor, with the function of measuring temperature and
humidity simultaneously. It can be used to accurately measure the temperature and humidity within the
range of 200 meters, and the collecting values of temperature and humidity are without error. Moroever,
H04DT can be used as an expansion module for any host PLC, with conversion accuracy of 9-12 bits.
The following we will introduce the expansion mode that expansion modulescan be hung directly behind the host PLC to achieve expansion, for example, one host PLC can be expanded with one H04DT module.

Select the “PLC hardware configuration” to add the module
Select the “PLC hardware configuration” to add the module
Right-click in the blank to add the required modules

9. H04DT Module hardware configuration
select the signal type of you want to configure
choose the conversion accuracy
zero correction

10. For example, we connect channel 1 of H04DT to a DS18B20 sensor and channel 3 to a SHT10 sensor.
After downloading the configuration of H04DT into the PLC, from the monitoring program we can see that the channels
of AI0 and AI2 have real-time display values. The temperature datas are returned by the two sensors. You can directly
use the two registers of AI0 and AI2.
Use the component status table to view
Use the monitoring window to view

11. We have access to a temperature and humidity sensor SHT10, but we only read the temperature in the AI2, then how to read the humidity measured by SHT10? For this special case, we need to use the FROM instruction to read the humidity value which is inside the register of SHT10. Let's take a brief look at the FROM instruction

12. EN - Enable：FROM will be executed when getting power, usually communication instructions should always keep the state of power supply. slot - Module position number：The position number of module located behind the PLC. CR - CR register be read：The register address which we want to read. N - Number of CR be read：The register number which we want to read ENO - Enable output：Instruction execution condition. OUT- Return start componet：The read back data stored into the register..

13. Use FROM to read the humidity value of the SHT10 sensor
H04DT is the first module behind the host plc, so fill 1 in the slot
According to the parameter information of module, the CR number of the humidity register of channel 3 is 22
Read the humidity value and store it in V100, humidity value: 30%
Read 1 register
The above demo is the usage method that expansion module H04DT connects with host PLC by the parallel line.

14. H32DT-Temperature Module
The digital temperature module of H32DT which supports 32-channel DS18B20 temperature sensor,
RW1820 temperature sensor, DS1990 sensor is built-in RS485 communication port which can support
remote function and be used as a remote IO module; It is widely used in coal mining, tunnels, refrigeration,
libraries, archives and other multi-point temperature measurement environment and other environmental
testing system.
For a better understanding about how to set the parameters when the modules are used as remote IO, the following we will take one H32DT as the remote IO module, to show the expansion mode and configuration parameters of remote modules.

16. Module hardware configuration
First, connect the expansion module H32DT to the PC by 485 cable, then open the programming software and find the remote module online option in the menu, finally make a remote module online, the default communication parameter for the module is N 8 2.
select the tool menu - remote module, or directly click on the shortcut icon of remote module button into the remote module interface

18. Remote module interface
Click the “online” button
Pop-up online window
Set the communication parameters, the module default N 8 2 RTU then click the “online” button to find the module

19. After the success of online, we can see the module parameter values which we can read and modify.

20. Module station number setting
Set the remote module station number (also called station address, communication address) via the 4-bit DIP switch on the hardware. Legal station number is 1 ~ 254 (0 is broadcast address). 4-bit DIP switch can be used to express the decimal number 1 to 15 (binary number from 0001 to 1111), through the DIP switch to modify the station number as follow: If the hard address expressed by the 4-bit DIP switch is not available or the module does not have a DIP switch, you can set the station number via the programming software. After online with the module, you can modify the module station number in "Address" of " Communication parameter " column, then click " Parameter download" to change the module station number.

21. then click the parameter download
You can modify the communication parameters in the communication parameter column. For example, if you want to change the station address to 8, then directly enter the address 8
Pop-up “download the parameter finished” indicates that parameters have been modified successfully.

22. Sensors configuration export
When the H32DT module is actually access with the sensors, we can see the serial number of actual access sensors. After using more sensors in the field and the positions have been fixed, you can save the configuration table by export, so that the positions of sensors and the registers are kept corresponding to facilitate on-site maintenance.

23. Click the “Export” button to pop up the export window
Select the path to save and click “Save”

24. Sensor configuration import
If you need to import the configuration table into the temperature module, click the “Import” button, find the configuration file to be imported, then click “Open”.
