8. 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.
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.
Extension 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.

Programmable Power Module Application Case
1. Expand Module Through the Host PLC Parallel Port
1.1. Module power supply
H02PW module is a programmable power module, the module itself can not be used as a power supply, it is used to control the
external power supply voltage or current constant output, so regardless of H02PW is extended through the parallel port of host
PLC or used as a remote module, it needs to supply DC24V ~ 62V power to the H02PW through the power input end of the
module.
1.2. The analog need't be written any conversion program, read the analog register value directly
For example, the host PLC T32S2T is expanded with one module H02PW through the parallel port
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:
One channel of the programmable power module H02PW occupies two AI registers (one AI register feedback voltage
measurement, unit: 0.01V and the other AI register feedback current measurement, unit: mA) and two AQ registers (one AQ
register control voltage output value, unit: 0.01V, the other AQ register control current output value, unit:mA)
1.3. Display analog values on SCADA and HMI
To display or set the measurement / output voltage of H02PW module on configuration, touch screen, text and other PC softwares,
you only need to set 2 decimal places on the numerical display primitive, because the measurement / output voltage unit of the
H02PW module is 0.01V. Then the values read in this way will be automatically reduced 100 times on the configuration, that is the
display converted to unit V, for example, you only need to set the decimal place to 2 on Haiwell Cloud configuration settings:

www.haiwell.com Haiwell PLC - Programmable Power Module Application Case

So the PLC reads the voltage measurement value AI0 of H02PW, AI0 = 1000, that is, the actual 10.00V, and there is no need to do
any data processing in the PLC and configuration, you can set 2 decimal places on display primitive, then it will be automatically
reduced by 100 times, displaying 10.00, which is the actual 10.00V.
1.4. Application example of module CR code: read and write PWM output period and output duty cycle from H02PW module
In this example, the H02PW PWM control is achieved by setting the PWM output period and output duty cycle of the H02PW
module. The PWM output period CR code of H02PW module is 18H ~ 19H (hexadecimal), PWM output duty cycle CR code is
1AH ~ 1BH (hexadecimal) (more CR content 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, H02PW is the first expansion module, so fill in 1;
CR: The PWM output period and duty cycle start CR code of the module is 18H, that is, 18H(hexadecimal)= 24(decimal), you
can directly input 24 or 0x18 to the instruction CR terminal;
N: Set the number, in this case, set 4 CR number.
Val: The data start component to be written into, in this case, the register of the power-down preserve area is used. When PLC
is powered on again, the setting value before power-off can be maintained.

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 port 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 for remote IO, it is necessary to supply power DC24V ~ DC62 to the power input end of the module. If
the module is powered normally, the PWR indicator will light.
2.2. Communication port introduction
1Modules are built-in RS485 port.
2Optional 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 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.
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:
There are three ways to configure remote IO parameters:
It can be configured via programming software - tools - remote modules (recommended);
It can be configured via the hardware configuration and TO instructions, when the module is hung behind the host PLC
through the parallel port;
It 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
Through 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.
Software operation steps
Click 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:
If there is only one machine connected with 485 line, then check "Find standalone"; if there are more than one, then remove the
button of "Find standalone", and set the start address and end address, so that all the machines connected with 485 line can be
found and achieve parameter configuration.
