9. Expansion modules installation
The PLC should be secured to an enclosed cabinet while mounting. For heat dissipation, make sure to provide a minimum space of
50mm between the unit and all sides of the cabinet. (See the figure.)
Rail Mounting: Use standard 35 mm rail.
Screw Mounting: Each MPU or extension module has two positioning screw holes, the diameter of the hole is 4.5mm. Please refer
to the dimension figure for the location of the positioning holes and their spacing. To avoid over temperature and for a better heat
dissipation, do not mount PLC to a position near to the bottom/top of the cabinet. Do not mount PLC in vertical direction.
Module Wiring: Connections between extension modules and connections between module and MPU are achieved through
bus.A extension cable will be configured to every extension module, for the connection between two different modules.Connection
methods: turn the right side of extended interface(the last MPU or extension module) over, plug the extension cable in the extended
interface, then press down the cover of the extended interface to reset the interface, the extended interface at the right side of the
module will be reserved for extension of the next module. Connect all extension modules in turn in the same way.

Temperature & Humidity modules Application Case
1. Expand module through the host PLC parallel port
1.1 Module power supply
Haiwell temperature and humidity module can be the expansion module for any host PLC; When the module is directly hung
behind the host PLC by parallel bus, no need to take external power supply, the module is powered by host PLC’ parallel port, if
the power supply of module is insufficient (the PWR power indicator does not light), then according to different models, the module
can be powered by 24VDC or 220VAC. When the module is extended through the parallel port, it is recommended to use 24VDC
module. Module power supply example:
1When the host PLC can be expanded to 7 modules, the PWR indicators of frist five modules are long bright, indicating the
modules power supply are normal, and if the PWR indicators of the 6th and 7th modules are not light, appearing
insufficient power supply, as long as the 6th and 7th modules are taken external power supply.
2When the host PLC is connected with 1 expansion module, because the host PLC provides power supply through the
parallel port, the PWR indicator of modue will light; If the module is added external power supply, it can still work, this time
the module will automatically determine and give priority to external power supply.
1.2 Temperature modules need't be written any conversion program, read the current temperature value directly when access
the sensor
For example, the host PLC T16S2T, respectively, is expanded with three modules of H04TC, H04RC and H08TC through the
parallel port from left to right, assuming the scene:
Thermocouple module H04TC input channel 1, signal type is K, input channel 2, signal type is E;
Thermal resistance module H04RC input channel 1, signal type is PT100, H04RC input channel 2, signal type is PT1000;
First enter the PLC programming software menu bar - view - hardware configuration, in accordance with the external order of
actual modules to add the module models, after added, the analog addresses will be automatically arranged, as shown below:
Haiwell temperature and humidity module need't be written any conversion program, for the above measuring temperature, we
only need to select the corresponding channel signal type, check the use of engineering value and full index number by default,
for example, the above module H04TC input channel 1, the signal type is K; the input channel 2, the signal type is E, as long as
we set the hardware configuration:
In this way, after configuration, as long as connect the K-type thermocouple to channel 1, then directly read AI0 register value, AI0

www.haiwell.com Haiwell PLC - Temperature & Humidity Module Application Case
11 / 23
= 123, that is the actual value of 12.3 ℃. In the same way, connect E-type thermocouple to channel 2, read AI2 value, such as AI2
= 3456, that is the actual value of 345.6 ℃.
As we know that Haiwell temperature and humidity modules can be set the signal type of each channel arbitrarily, so for the
H04RC module, after configuration, we can read the temperature value directly when connecting the corresponding sensor to the
channel.
1.3 Programming skills for PLC
1If you want to write the alarm program that temperature exceeds the setting value, for example, when the temperature is
more than 125℃, it will alarm, the program of PLC can be written as follows:
1.4 Display temperature value on SCADA, HMI
If the configuration, touch screen, text and other PC softwares want to display the current temperature, only need to set 1 decimal
place on the numerical display primitive, then the read value will be automatically reduced 10 times in the configuration, that is the
actual temperature value, for example, you can set 1 on decimal places of Haiwell Cloud SCADA settings:
So that when the PLC read AI0 value, AI0=123, that is the actual value of 12.3℃, there is no need to have data processing in PLC
and configuration, only set the 1 decimal places on the numerical display primitive, then it will be automatically reduced by 10
times, displaying value of 12.3, that is the actual value of 12.3℃.
1.5 Default for using engineering, when the engineering value is not used, the default code value is 0 ~ 32000
When using the engineering value, the linear transformation is specified by the lower limit and the upper limit value, and the
program is automatically transformed. When the engineering value is not used, all types are unified to correspond with 0 ~ 32000
code value.The same case of temperature measurement, this time can according to the linear transformation formula: Out = (In -
InDw) * (OutUp- OutDw) / (InUp- InDw) + OutDw to write the conversion program, or use the SC linear transformation instructions
to calculate directly.
Haiwell analog used easily, it is recommended to check the use of engineering value, so that the analog will be very convenient
without writing any program.

1.6 Module CR code application example: Read module channel disconnection alarm
In this example, in order to read the external sensor disconnection information of H04TC module, the disconnection alarm data of
H04TC module input channel 1-4 is stored in CR29, that is, 29H (hexadecimal), decimal 41. (More CR contents can be found in
the software online help - hardware manual - expansion module parameters within the corresponding model). This program is as
follows:
Slot: Position number, H04TC is the first module, so fill in 1;
CR: Module disconnection alarm CR41, that is, 29H (hexadecimal) = 41 (decimal), it can be directly input 41 or 0x29 into the
instruction CR terminal;
N: Number for readings, 1 register for 16 bits, low 4 bits is corresponding channel 1-4, disconnection for 1 (ON), normal for 0
(OFF).
2. Module used as remote IO
Haiwell PLC expansion module is built-in one RS485 communication port(Some models with Ethernet communication port), which
not only supports parallel bus(Use the expansion bus to connect with the parallel interface of host PLC), but also supports serial
bus(Use the RS485 communication port of module networking with communication port of host PLC, and host PLC controls the
remote module by communication instructions), when using the serial bus to expand (that is, remote IO module), it doesn't have
expansion limit of system points and can be distributed installation.
Distributed installation is very important for the system which needs to collect and monitor a large number of decentralized digital
or analog signals(temperature, humidity, differential pressure, blowing rate, flow, fan speed, valve opening, etc.), it can easily
achieve distributed installation control and unlimited points of expansion, greatly improving the control system configuration
flexibility and future control expansion capabilities, reducing the number of signal wiring, also reducing the interference problem of
too long analog signal line, saving the project investment costs.
The following will introduce the operation key points and techniques of modules used as remote IO.
1.1 Module power supply
When the module is used as remote IO, there are two optional models of 24VDC and 220VAC, such as H08RC model for the DC
24V power supply. H08RC2 for AC 220V power supply. If the module is powered normally, the PWR indicator will light.
1.2 Communication port introduction
1All analog modules are built-in RS485 port.
2As for 8-point analog module, you can choose the Ethernet port.
3RS485 communication port and Ethernet port can be used at the same time, for example, the RS485 of module
communicates with PLC, Ethernet port can also communicates with multiple host computers (up to 7).
1.3 Communication protocols and default parameters
1RS485: Support standard Modbus RTU / ASCII protocol, it can communicate with the configuration, touch screen, text
display, PLC and other third-party host computer, which must support Modbus protocol. Among them:
Address: 1 ~ 254 can be set; module address is divided into soft address and hard address, hard address has the highest
priority.

www.haiwell.com Haiwell PLC - Temperature & Humidity Module Application Case
13 / 23
Soft address: The address set through programming software - remote tool, address range 1-254;
Hard address: The address set through the 4-bit DIP switch of module hardware, address range 1-15. Hardware address
setting example:
Baud rate：2400, 4800, 9600, 19200, 38400, 57600, 115200 optional;
Data format : N, 8, 2 RTU, E, 8, 1 RTU, O, 8, 1 RTU, N, 8, 1 RTU, E, 7, 1 ASCII, O, 7, 1 ASCII, N，7，2 ASCII
optional.
RS485 default parameter：19200，N 8 2 RTU，station number is 1.
2Ethernet +: Support the standard Modbus TCP protocol, it can communicate with the configuration, touch screen, PLC
and other third-party host computers, which must support Modbus TCP protocol. Among them:
Ethernet default parameters:
IP: 192.168.1.111
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
1.4 Introduce module parameter configuration method when the module is used as remote IO
There are three ways to configure remote IO parameters:
1It can be configured via programming software - tools - remote modules (recommended);
2It can be configured via the hardware configuration and TO instructions, when the module is hung behind the host PLC
through the parallel port;
3It can be configured via MODW instructions through the serial communication.
1.5 Parameter configuration example: Configurate module by programming software remote module tool
1.5.1 Hardware connection:
1Through the RS485 communication port (the terminals of A +,B- on the module) connection: If the computer has a serial
port, you can use the converter of 232 to 485 connecting with the module; if it has one USB interface, you can use the
converter of USB to 485 connecting with the module.
2Through the connection of Ethernet + communication interface: You can connect the module with the computer's
network port directly by the standard network cable, or take the computer and module connected to the switch.
1.5.2 Software operation steps:
1Click on the the menu bar tool of programming software- "remote module":
Click the button in the pop-up window to open the "Online" window. The module default address is 1,19200, N 8 2
RTU, the online success is as follows:

14 / 23
If there is only one machine connected with 485 line, then check "stand-alone search"; if there are more than one, then
remove the button of "stand-alone search", and set the start address and end address, so that all the machines connected
with 485 line can be found and achieve parameter configuration.
Click to exit, enter the configuration interface, as shown below:
We can change the module name, address, IP, subnet mask, baud rate, data format and other communication parameters in
the communication parameter area.
In the external analog input area, we can set the signal type of each channel, choose whether to use engineering value or
not((for temperature module, the default use of engineering value)), the upper and lower limits of engineering value(it can be
set if you check the use of engineering value), sampling times and zero correction.

www.haiwell.com Haiwell PLC - Temperature & Humidity Module Application Case
15 / 23
After setting, select the "Download parameter" to download the parameter into the module.
In addition, we can do the following operations through the remote module tool:
1Online monitor the channel value of module, error code.
2Upload the module paramater, upgrade the module firmware, then make the module support new features.
3It can export the module configuration to save or import and restore the default value.
1.6 Remote IO appliciation example(RS485 mode): PLC reads 4-channel temperature value of H04RC module
1Hardware wiring: PLC connects to 485 port of module by shielded twisted pair, A + connects to A +, B- connects to B-, if
the PLC connects to multiple remote IO modules, it needs to use hand in hand way to connect.
2Modbus address: From the above 4-channel analog CR parameter table shows that, the channel 1 ~ 4 input values are
stored in 10H ~ 13H of H04RC module.
3PLC program: Host PLC wants to read the 4-channel temperature values of remote IO module H04RC, 4-channel
temperature sensors for PT100, -2000 ~ 8500 indicates -200.0 ~ 850.0 ℃. In this example, H04RC communication is
the default parameter: Station number address is 1, baud rate is 19200, data format is N 8 2 RTU. The program of PLC
reads the 4-channel temperature values is as follows:
The host PLC reads the 4-channel temperature values of H04RC by Modbus read instruction MODR, the start address is 10H
(hexadecimal), that is, the decimal value is 16. When the communication is successful, M0 is ON, the temperature values which
are read back will be stored in V0-3, V0=235, indicating that the actual temperature of the first channel is 23.5℃, the same as
V3=867, indicating that the actual temperature of the fourth channel is 86.7℃.
1.7 Remote IO appliciation example (Ethernet mode): PLC reads and writes every channel input values of H08RC-e module
1Hardware wiring: PLC and module Ethernet port connected with a shielded network cable, they can be connected directly

or through the switch.
2Modbus address: From the above H08RC-e analog module CR parameter table shows that the input values of 8-channel
thermal resistance module input channel 1 ~ 8 are stored in the address 10H ~ 17H.
3PLC program: Read the 8-channel measurements of remote Ethernet module H08RC-e, if the module IP address is
192.168.1.112, station number address is 1, the read results are stored in the V10 ~ V17, as follows:
1.8 Remote IO appliciation example: Haiwell Cloud configuration communicates directly with H08TC module
11, Open Haiwell SCADA software, select the "new project", choose to add the device in the "device", then choose serial
port or Ethernet according to the module which supports the Ethernet or RS485, this example for serial port, the serial port
number of USB to 485 is COM12, as shown below:
Default parameter 19200 N 8 2 RTU for the module, station number address is 1. And directly select Haiwell remote
module driver in serial port：
Click OK, then we are prompted to start set up variables, the establishment of eight variables indicates 8 channels:

www.haiwell.com Haiwell PLC - Temperature & Humidity Module Application Case

Then set up the screen, we can use the display primitives to bind the corresponding channel variable values. If you need to
display the decimal places, it can set the corresponding decimal places on the display primitive. As shown below:
1.9 H04DT module usage features introduction
H04DT module supports digital temperature sensors: DS18B20, RW1820, DS1990 and temperature & humidity sensors SHT1x,
SHT7x.
In the process of program configuration, for sensors DS18B20, RW1820, DS1990, they all select the signal type of DS18B20, for
temperature & humidity sensors SHT1x, SHT7x, they all select the signal type of SHT11. as follows:
In addition, we can see that when choosing to measure the temperature and humidity, the analog input register does not appear
two consecutive addresses, such as the above channel 2 and 3 are connected to temperature & humidity sensor SHT11 , but only
one AI1 and AI2 indicates the measured temperature value. So how to read the humidity value?
Way to read the humidity value: First of all, we refer to the online help of programming software - hardware manual - expansion
module parameters - digital temperature module parameter table shows that H04DT humidity value is stored in the CR register
CR14 ~ 17, it indicates the humidity value of channel 1 ~ 4 when the channel is selected as a temperature and humidity sensor, so
we can read humidity value through the FROM instruction, in this case, H04DT is the first module near the host PLC, so Slot = 1.
The program is as follows:
In this way, we can read back the humidity value of the DT module.

1.10 H32DT module usage features introduction
H32DT supports sensor signal types: DS18B20, RW1820, DS1990.
Module parameters: H32DT module has 2 channels, each channel can measure the maximum 16 points of temperature, a total of
32 temperature points can be measured. Measuring temperature range: -55 ~ +125 ℃,≤200m distance to per channel (line
resistance 50Ω). So, how to use the H32DT module properly?
The following are the main points of this section:
1Remote module tool usage;
2How to wire sensor?
3how to replace broken sensor?
4how to replace broken module?
First, let's look at the hardware wiring. How to connect H32DT with the remote module tools of PLC software?
Hardware connection and power supply: PC-side USB transferred to 485 (PC with serial port can also use 232-to-485 converter),
then connected to the communication port A + B- of 485 in H32DT module. H32DT module is powered by DC24V switching power
supply. After the module is powered on, then click the menu bar tools - Remote module - Online, when online successfully, you will
see:
Click "exit", or "×" to exit. In the absence of sensors, the default parameters of the module are shown below:
Then, we start to access sensors (the strict wiring diagram please refer to the above digital module wiring diagram), as shown in
the following figure, we access the first sensor # 1:

3Numerical 1250 indicates that the maximum value of engineering quantity displayed by the channel (-55 ~ + 125℃, that
is, -550 ~ 1250) when the sensor is not connected.
Then we access the second sensor (for the strict wiring diagram, please refer to the above digital module wiring diagram), the
access interval time of adjacent sensors should be greater than 10 seconds. Wiring diagram is as follows:

After the 16 sensors of channel 1 accessed, channel 2 is accessed in the same way, when accessed, we follow the way from near
to far or from far to near. After finishing the access of all sensors, we have to save the configuration parameters of H32DT module,
this step is very important! (The back will introduce the application occasions). The specific operation is as follows, in the menu
bar of remote module tool has an export function, we click export:
After export, click save：
The above operation, the module line is connected, the parameters are also saved. Next host PLC needs to read the temperature
from the module.
H32DT can communicate with the host PLC through the parallel port, also through the 485 port, H32DT used as the remote IO, it
can communicate with the host PLC.
We can see according to the online help of PLC software - Hardware Manual - Expansion Module Parameters - Digital
Temperature And Humidity Module Parameter Table, or the above 《8.1 Digital Temperature and Humidity Module Parameter
Table》, the temperature values of channels 1 and 2 exist in the module CR register.
