11. Mounting and installation
The PLC should be secured to an enclosed cabinet while mounting. For heat dissipation, make sure to provide a minimum
clearance 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 expansion 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.
Expansion Module Wiring: Connections between expansion modules and connections between module and MPU are achieved
through bus. One expansion cable will be configured to every expansion module, for the connection between two different
modules.Connection methods: turn the right side of extended interface(the last MPU or expansion module) over, plug the
expansion 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 expansion of the next module. Connect all expansion
modules in turn in the same way.

Analog Module Application Case
1. Expand module through the host PLC parallel port
1.1. Module power supply
Analog 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 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. The analog need't be written any conversion program, read the analog register value directly.
For example, the host PLC T16S2T, respectively, is expanded with three modules of S04AI, S04AO and S08XA through the
parallel port from left to right, assuming the scene:
Analog module S04AI input channel 1, signal type is 4-20mA, used to measure the pressure, the pressure range of
0.0~3.0Mpa;
Analog module S04AO input channel 1, signal type is 0-10V, used to control the inverter frequency of 0.0~50.0Hz;
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 address will be automatically arranged, as shown below:
Haiwell analog module need't be written any conversion program, as for above pressure measurement, we only need to check
the use of engineering value, set the lower limit value of 0 corresponding 0.0Mpa, set the upper limit value of 3000 indicating
3.000Mpa, the upper limit value 3000 hidden three decimal places can achieve magnification times and improve accuracy.
Then we read the value of the analog input register AI0, if AI0 = 1234, then the actual value is 1.234Mpa.

www.haiwell.com Haiwell PLC - Analog Module Application Case
10 / 18
Similarly, for the analog output, check the use of engineering value, set the lower limit value of 0 indicating 0.0Hz, set the upper
limit value of 500 indicating 50.0Hz, if you want the inverter frequency output is 25.6Hz, as long as force the AQ0 value as 256
or through other logic instructions to output the AQ0 value of 256. As shown below:
1.3. Programming skills
If you want to write the alarm program that pressure exceeds the setting value,for example, when the pressure is more than
1.25Mpa, it will alarm, the program of PLC can be written as follows:
1.4. Display analog value on SCADA, HMI
If the configuration, touch screen, text and other
PC software want to display the current pressure,
only need to set three decimal places on the
numerical display primitive, then the read value
will be automatically reduced 1000 times in the
configuration, that is the actual temperature value,
for example, you can set 3 on decimal places of
Haiwell Cloud SCADA settings.
So that when the PLC read AI0 value, AI0=1234,
that is the actual value of 1.234Mpa, there is no
need to have data processing in PLC and
configuration, only set the 3 decimal places on the
numerical display primitive, then it will be
automatically reduced by 1000 times, displaying
value of 1.234, that is the actual value of
1.234Mpa.

1.5. 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 pressure 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 the module channel disconnection alarm
In this example, in order to read the external sensor disconnection information of S08XA module, the disconnection alarm data
of S08XA 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, S08XA is the third module, so fill in 3;
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 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.
2.1. Module power supply
When the module is used as remote IO, there are two optional models of 24VDC and 220VAC, such as S08AI model for the DC
24V power supply. S08AI2 for AC 220V power supply. If the module is powered normally, the PWR indicator will light.
2.2. 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).
2.3. Communication protocols and default parameters
RS485: Support standard Modbus RTU / ASCII protocol, it can communicate with the configuration, touch screen, text, 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.
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.

Ethernet +: 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
2.4. Module parameter configuration method introduction, 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.
2.5. Parameter configuration example: The module is configured by programming software remote module tool
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.
Software operation steps

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,
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.

After setting, select the "parameter download" to download the parameter into the module.
In addition, we can do the following operations through the remote module tool:
Online monitoring the channel value of module, error code.
Upload the module paramater, upgrade the module firmware, then make the module support new features.
It can export the module configuration to save or import and restore the default value.
2.6. Remote IO application example(RS485 mode): The PLC read the 4 communication temperature values of S04AI 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 S04AI module.
3PLC program: Host PLC wants to read the 4-channel liquid level values of remote IO module S04AI, 0 ~ 1000 indicates
that 0 ~ 1.0m. In this example, S04AI 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 liquid level values is as follows:
The host PLC reads the 4-channel liquid level values of S04AI 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 liquid level
values which are read back will be stored in V0-3, V0=235, indicating that the actual temperature of the first channel is
0.235m, the same as V3=867, indicating that the actual temperature of the fourth channel is 0.867m.
2.7. Remote IO application example (RS485 mode): The PLC writes the 8-channel output values of S08AO module
1Hardware wiring: PLC connects to 485 port of module by shielded twisted pair, A + connects to A +, B- connects to B-, if

2Modbus address: From the above 8-channel analog CR parameter table shows that, the channel 1 ~ 8 output values of
S08AO module are stored in address 10H~17H .
3PLC program: Host PLC wants to write the 8-channel analog output values of remote IO module S08AO. In this example,
S08AO communication parameters: Station number address is 2 (set by DIP switch), baud rate 19200, data format N 8 2
RTU. The program of writing 8-channel analog output values is as follows:

www.haiwell.com Haiwell PLC - Analog Module Application Case
16 / 18
Host PLC writes the 8-channel analog output values of S08AO by Modbus write instruction MODW, the start address is
10H(hexadecimal), that is, the decimal value is 16. When writing successfully, M1 is ON, the 8-channel values which will
be written into are stored in V1000-1007.
In this example, for the channel 1 of analog output, check the use of engineering value, the lower limit value is 0, the
upper limit value is 3600, indicating that the valve opening is 0.0~360.0 °, this case V1000=500, so the first output
channel value is 500, that is, the valve opening is 50.0°.
2.8. Remote IO application example(Ethernet mode): PLC read and write each channel input and output values of S08XA-e
1Hardware wiring: PLC and module Ethernet port connected with a shielded network cable, they can be connected
