Expansion modules installation

The PLC should be secured to an enclosed cabinet while mounting.,For heat dissipation, make sure to provide enough space

between the unit and all sides of the cabinet. (See the figure.)

Rail Mounting: Use standard 35 mm rail.

Expansion module connection method

The parallel interface on the lower right side of the last module (MPU or expansion module) is inserted into the parallel interface on the lower

left side of the next module and hooked with small cards on both sides. The parallel interface on the right side of this module is used as the

next expansion module. Connect all expansion modules in this way in sequence.

8 / 11

Temperature & Humidity modules Application Case

1. Module power supply

It can be used as the extension module of HCS/G/M series PLC MPU; when the module is hung behind the MPU through the

expansion port,, the external power supply is not required, and the module is powered by the parallel port of the MPU. If the power

supply of the module is insufficient (the PWR power indicator on the module is not on).

2. Temperature modules needn't be written any conversion program, read the current temperature value directly when access the

sensor

For example, the MPU HCG-8X8Y-TN respectively is expanded with three modules of AE-4TC、AE-4RC and AE-8TC through the

parallel port from left to right, assuming the scene:

Thermocouple module AE-4TC input channel 1, signal type is K, input channel 2, signal type is E;

Thermal resistance module AE-4RC input channel 1, signal type is PT100, AE-4RC 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:

HNC 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 AE-4TC 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

= 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 HNC temperature and humidity modules can be set the signal type of each channel arbitrarily, so for the AE-4RC

module, after configuration, we can read the temperature value directly when connecting the corresponding sensor to the

channel.

3. Programming skills for PLC

If 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:

4. Display temperature value on 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 HTCloud Designer 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℃.

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.

HNC 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.

6. Module CR code application example: Read module channel disconnection alarm

In this example, in order to read the external sensor disconnection information of AE-4TC module, the disconnection alarm data of

AE-4TC 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:

10 / 11

Slot: Position number, AE-4TC 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).
