4. 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)

5. 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

6. 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.

7. 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.

11. 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

12. 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

13. 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..

14. 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.

15. 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.

21. 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.

22. 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.

23. 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.

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

30. Load Cell Module Load Cell Module principle
When the metal material is subjected to pulling or tension, the metal material becomes thinner, and the electrical impedance increases. Likewise if the metal material is compressed, the metal impedance decreases. The weighing module is a strain gauge using this theory. This kind of sensor can transform the physical pressure into electrical signals, so it is often used in load cell, tension, pressure occasions.

39. bit0: No load (zero weight) bit1: Exceed the upper limit of weight
bit2: The measured value is stable
bit3~15: Reservations
Status Code
Bit0: No load (zero weight): when weighing is not placed with any object, this bit is ON.
Bit1: Exceed the upper limit of weight. When the current weight exceeds the set limit of CR 24H, this bit is ON.
Bit2: The measured value is stable, which is related to CR20H and CR21H.
Bit3~15: Reservations
Generally used for auxiliary control and automatic judgement.

40. Tare weight Bit1 = ON 1AH Bit1 = OFF
1. Write the value 1 to CR25H, read the current weight value (10H) as tare weight. Tare weight value is stored in the 19H
2. CR19H store the tare value.
3. Enable control settings. It is controlled by Bit1 of CR1AH. 0- gross weight, 1- net weight.
Switch the weight of the current display to be gross or net weight. Use value of CR19H as the tare weight in the calculation.
Tare weight
Bit1 = ON
The result is net weight = 10H - 19H
1AH
Bit1 = OFF
The result is gross weight = 10H

41. Zero-point detection function
By using the zero-point detection function, we can know whether the object has been removed from the weighing module, and judge whether the zero-point weight Bit is 1, indicating that the object has been removed from the weighing module, then we can continue to do the next control.Related control register: CR23H zero-point detection range
Zero-point detection function
