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.

HNC PLC - Analog Module Application Case

Analog Module Application Case

Module used as remote IO

HNC TE series remote module is built-in one RS485 communication port (Some models with Ethernet communication port), which

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.

1.1. Module power supply

When the module is used as remote IO, there are two optional models of 24VDC.If the module is powered normally, the PWR

indicator will light.

1.2. Communication port introduction

All analog modules are built-in RS485 port.

As for 8-channel analog module, you can choose the Ethernet port.

RS485 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 6).

1.3. 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 standard 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.

9/15

HNC PLC - Analog Module Application Case

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

1.4. Module parameter configuration method introduction, when the module is used as remote IO

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 MODW instructions through the serial communication.

1.5. 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.

Through 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

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:

10 / 15

HNC PLC - Analog Module Application Case

If there is only one machine connected with RS485, 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 RS485

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.

11 / 15

HNC PLC - Analog Module Application Case

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.

1.6. Remote IO application example(RS485 mode): The PLC read the 4 communication temperature values of TE-4AD module

Hardware 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.

Modbus address: From the above 4-channel analog CR parameter table shows that, the channel 1 ~ 4 input values are

stored in 10H ~ 13H of TE-4AD module.

PLC program: Host PLC wants to read the 4-channel liquid level values of remote IO module TE-4AD, 0 ~ 1000 indicates

that 0 ~ 1.0m. In this example, TE-4AD 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 TE-4AD 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-V3, 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.

1.7. Remote IO application example (RS485 mode): The PLC writes the 8-channel output values of TE-8DA module

Hardware 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.

12 / 15

HNC PLC - Analog Module Application Case

Modbus address: From the above 8-channel analog CR parameter table shows that, the channel 1 ~ 8 output values of

TE-8DA module are stored in address 10H~17H .

PLC program: Host PLC wants to write the 8-channel analog output values of remote IO module TE-8DA. In this example,

TE-8DA 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:

Host PLC writes the 8-channel analog output values of TE-8DA 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°.

1.8. Remote IO application example(Ethernet mode): PLC read and write each channel input and output values of

TE-4AD4DAe

Hardware wiring: PLC and module Ethernet port connected with a shielded network cable, they can be connected

directly or through the switch.

Modbus address: From the above TE-4AD4DAe analog module CR parameter table shows that the input values of

module input channel 1 ~ 4 are stored in the address 10H ~ 13H. The output values of module output channel 1-4 are

stored in 2AH ~ 2DH.

PLC program: Read the 4-channel measurements of remote Ethernet module TE-4AD4DAe and write the 4-channel

output values of TE-4AD4DAe, if the module IP address is 192.168.1.112, station number address is 1, the read results

are stored in the V0 ~ V3, the values to be written are stored in the register V10-V13. As follows:
