3.1 Input specifications

3.2 Environmental specification

3.3 Software specification

3.4 Accuracy calculation

Within the working temperature range, when the temperature change rate is less than 0.3 °C/min, the accuracy of this product = ADC sampling accuracy + cold junction compensation error. According to the test principle, it is need to wait for the module to be powered on for 45 minutes before measuring.

Recommended: Within the working temperature range and under the condition of horizontal and vertical installation direction, when the adjacent module is a temperature module, the cold end compensation error is within ±3℃.

Not recommended: Adjacent modules consume more than 3.5 W of power, for example host PLC, LX6V - 32EXYT.

4 Usage

This module is suitable for Wecon LX6 series PLC and LX6V - EM£ - ECAT module equipment. The two usage methods are as follow.

4.1 Use on LX6V/LX6S

The parameter configuration interface is as below:

Upper computer expansion module configuration process description:

① Double - click the expansion module configuration to open the configuration interface;

② Adding new modules according to the model and position of the current module connected;

③ Double - click the module in the current machine slot to open the parameter configuration interface;

1. TC general configuration

① Thermocouple cold junction compensation: Set whether the module enables cold junction compensation, and the cold junction compensation is enabled by default;

② Temperature unit: Set the temperature unit output by the module, and the supported temperature unit types are Celsius (℃) or Fahrenheit (℉), the default unit is: Celsius;

③ Power frequency suppression: Set the power frequency suppression of the module to suppress 50Hz or suppress 60Hz. The default suppression is 50Hz. Please set the appropriate power frequency suppression option for the module according to the actual application scenario;

      2. TC channel configuration

① Enable channels: It can be set whether to enable the current expansion module channel;

② Sensor type: Set the sensor type connected to the module channel, the default sensor type is K to type, there are 8 types of sensors supported by TC module, which are: K, J, E, B, N, R, S, T; The temperature range that can be measured by each sensor is as follows:

③Filtering time: The supported filtering time is 0 to 100s, it is used to reduce fluctuations in channel temperature data. The default filtering time is 5s. Please choose the appropriate filtering time according to the requirements of actual application scenarios for channel output data;

④ Enable overlimit detection: Channel temperature data overlimit judgment switch, when overlimit detection is enabled, the upper and lower limits of temperature can be set. When the temperature output by the channel is greater than the upper limit of temperature or less than the lower limit of temperature, the state of this channel will output a channel over to limit warning;

⑤ Enable temperature offset: Channel temperature data offset enable switch. When temperature offset is enabled, the output temperature data of the channel will be offset;

     3. I/O mapping

By default, channel are mapped into the R device according to the current number of module channels. The following figure shows the mapping of the modules CH1 to CH12 to the R0 to R11 device. The temperature value data type of the channel is REAL. If it is necessary to display the channel 1 The temperature value can be viewed after assigning a variable using the DEMOV instruction.

    4. Download configuration

 Click OK to save the configuration,according to the interface shown in the figure to download the module configuration to the PLC.

4.2 Used on LX6V to EM□ to ECAT module

1. First add EtherCAT device

According to steps ① to ④ in the figure below, right to click EtherCAT, and click [New] to >[Import] to import the ESI device description file of the device;

After the import is completed, select the coupler according to themodule model and location connected to PLC (the figure below takes LX6V to EMB to ECAT as an example);

1. Configuration module

Right to click the currently added coupler to add the expansion module mounted to the current coupler.

✎Note: When the configuration module is inconsistent with the actual mounted module, an error will be reported that the OP cannot be successful.

1. Configure module parameters

General configuration

① TC module thermocouple compensation: Set whether the module enables cold junction compensation, and the cold junction compensation is enabled by default;

0: No cold junction compensation;

Others: Enable cold junction compensation;

② TC module temperature unit: Set the temperature unit output by the module. The supported temperature unit types are Celsius (℃) or Fahrenheit (℉). The default unit is: Celsius;

0: Degrees Celsius (℃);

Others: Degrees Fahrenheit (℉);

③ TC module power frequency support: Set the power frequency suppression of the module to suppress 50Hz or suppress 60Hz, and the default suppression is 50Hz;

0: Suppress 50 Hz;

Others: Suppress 60 Hz;

④ Reserve: Reserve;

⑤ CHx sensor type: Set the type of sensor connected to the channel;

Supported sensor types:

0: Not enabled

1: K;

2: J;

3: E;

4: B;

5: N

6: R

7: S

8: T

⑥ CHx filtering time: Used to specify the filtering time of the current channel. The supported filtering time is 0 to 100s, it is used to reduce the fluctuation of channel temperature data. The default filtering time is 5s;

⑦ CHx overlimit detection: Overlimit detection enables configuration, 0: Overlimit detection detection is not enabled, others: Enable over limit detection

⑧ CHx temperature upper limit: The upper limit value of the channel over limit detection temperature;

⑨ CHx temperature lower limit: The lower limit value of the channel overlimit detection temperature;

⑩ CHx temperature offset: The offset of channel data, supported offset range: - 300 to + 300；

I/O mapping

The temperature and state of the module can be mapped to variables/device. For example, the following figure maps the temperature values of the CH0 to CH3 channels to the D0 to D7 device, and the status codes of the CH0 to CH3 channels to the D8 to D11 device.
