For example, the input voltage of the TC terminal of the temperature transmitter is 5000 μV and the temperature
of the cold terminal is 25 ° C. According to the formula, the voltage value corresponding to the temperature of the
cold terminal can be calculated：
URJ = 3.94 * 10-1 + 3.94 * 101 * 25 + 2.65 * 10-2 * 252 - 1.11 * 10-4 * 253 = 1000 μV
Add this voltage to the input terminal of TC (5000 + 1000) and then calculate the corresponding temperature value
according to the calculation formula:
4.18 + 2.26 * 10-2 * 6000 + 1.41 * 10-7 * 60002 + 1.50 * 10-11 * 60003 - 1.35 * 10-15 * 60004 = 146.3 °C

bus. Open the NI-FBUS Configurator software, and the NCS-TT106F device will be detected on the interface. As
shown in Figure 3.5 below. In the figure, NCS-TT106F has one resource block, 2 transducer blocks, 2 AI function
blocks and 1 PID function block.

3.4.4 Sensor configuration
When using the NCS-TT106F temperature transmitter, the related parameters should be configured in the
transducer block according to the connected sensor model. Open the transducer block TEMP_SENSOR1, change
the TARGET in the MODE_BLK parameter of the transducer block to OOS, and configure the sensor type and
connection cable system under the SENSOR_TYPE and SENSOR_CONNECTION lists. Take the PT100 three-wire

Auto, and the ACTUAL parameter in the MODE_BLK parameter should be Auto, otherwise modify the configuration
according to the prompt of the BLOCK parameter. You can see the current temperature value and status collected
by the PT100 sensor in the PRIMARY_VALUE parameter. As shown in Figure 3.7 below.
Figure 3.7 Temp erature meas urement val ue d isplay inte rface
3.4.5 Two-wire zero calibration configuration

http://www.microcyber.cn/en
~ 12 ~
In the two-wire measurement, the two-wire zero calibration can be performed by the
TWO_WIRES_COMPENSATION parameter of the transducer block. The specific method is as follows：
First, give the channel zero value, that is, short the two ends of the channel.
Secondly, set the parameter TWO_WIRES_COMPENSATION to Start, click the "Write Changes" button.
Finally, after successful writing, read the TWO_WIRES_COMPENSATION parameter and click the "Read All" button
until the two-wire zero calibration is successful when the value of this parameter is Finish.
3.4.6 Two-point linearization calibration
NCS-TT106F temperature transmitter has undergone rigorous calibration work before leaving the factory, in general,
no user calibration is required. Users can use parameters CAL_POINT_HI, CAL_POINT_LO, and CAL_UNIT to achieve
two-point linearization calibration. The following uses mV signal two-point linearization calibration as an example.
The operation steps are as follows:
（1）Set the TEMP_SENSOR1 MODE parameter of the transducer block to OOS, and set the SENSOR_TYPE
parameter to-/ + 100mV. Set the calibration unit parameter CAL_UNIT to mV according to the sensor type, and set
the parameter SENSOR_CAL_METHOD to “User Trim Standard Calibration”. The setting diagram is shown in Figure
3.8 below.
Figure 3.8 Two-point linearization calibration configuration diagram
（2）Calibrate the lower limit mV signal to the acquisition channel through the standard mV signal source. After
stabilization, write the output value of the standard mV signal source to the CAL_POINT_LO parameter and click
the "Write Changes" button. Similarly, the standard mV signal source is used to output the upper calibration mV

http://www.microcyber.cn/en
~ 13 ~
signal to the acquisition channel. After stabilization, write the output value of the standard mV signal source to the
CAL_POINT_HI parameter and click the "Write Changes" button. No prompt for writing errors indicates that the
calibration was successful. As shown in Figure 3.9 below, the lower limit of the calibration mV signal is -80mV, and
the upper limit of the calibration mV signal is 80mV. Note that the written calibration data and the actual input
channel data must not have a large deviation, otherwise the calibration will fail.
Figure 3.9 Two-point linearization calibration configuration diagram
After completing the above steps, set the TEMP_SENSOR1 MODE parameter of the transducer block to Auto, and
mV signal acquisition can be performed normally. BIAS is the offset parameter, and the offset function is valid in
this mode. In Celsius, the two-point linearization calibration principle of the ohmic signal is the same as the
calibration principle of the mV signal.
3.4.7 Multipoint linearization calibration
NCS-TT106F temperature transmitter has the function of multi-point linearization calibration. It can support up to
16 calibration points. The user can choose whether to enable it according to his needs. Through the calibration
parameters TAB_X_Y_VALUE1-TAB_X_Y_VALUE16 of the CUSTOM_BLOCK1 transducer block, the user can
complete the multi-point linear calibration of the instrument by himself. The calibration procedure is as follows：
（1）The NCS-TT106F temperature transmitter provides 16 calibration point inputs, namely the TAB_X_Y_VALUE1-
TAB_X_Y_VALUE16 array of parameters of the transducer block. The user can write the output values to be
calibrated into the array in turn and select a good unit. For example, when performing three-point interpolation
calibration, the user can select 10, 20, and 30 as calibration points, and write the three values in the second place
in the TAB_X_Y_VALUE1, TAB_X_Y_VALUE2, and TAB_X_Y_VALUE3 arrays, as shown in Figure 3.10.

http://www.microcyber.cn/en
~ 14 ~
Figure 3.10 Calibration point configuration
（2）Input the standard signal through the standard source, and open the transducer block TEMP_SENSOR1 in the
configuration software, read the value of the parameter PRIMARY_VALUE, and write the value to the first place in
the TAB_X_Y_VALUE1, TAB_X_Y_VALUE2, and TAB_X_Y_VALUE3 arrays. For example, write the read 10.2, 20.5, 30.4
in the array, and set the parameter ENABLE_TAB_X_Y to "Enable" as shown in Figure 3.11. This is the end of
calibration work.
Figure 3.11 Acquisition parameter configuration
(3) Open the transducer block TEMP_SENSOR1, set the MODE parameter to OOS, and set the parameter
SENSOR_CAL_METHOD to “User Trim special Calibration”. After successful setting, set the MODE parameter to Auto,
and the temperature transmitter will work according to the calibrated characteristic curve.
3.4.8 Enabling cold junction temperature compensation
When using the thermocouple as the sensor, the user can set the cold junction compensation through the

http://www.microcyber.cn/en
~ 15 ~
parameter RJ_TYPE, and set it to Internal to enable the internal cold junction compensation. At this time, the value
of RJ_TEMP is the temperature value measured internally, that is, the value of the parameter SENCANDARY_VALUE;
External can configure a fixed cold junction compensation value by setting the value of EXTERNAL_RJ_VALUE. At
this time, the value of RJ_TEMP is the value of EXTERNAL_RJ_VALUE; when it is set to External PT100, the
temperature can be measured by an external two-wire PT100 sensor as the cold junction compensation value;
setting No reference can disable cold junction compensation, as shown in Figure 3.12.
Figure 3.12 RJ_TYPE configuration
3.5 Function block configuration
NCS-TT106F temperature transmitter has 2 AI function blocks and a PID function block, each function block
conforms to the FOUNDATION fieldbus standard. When NCS-TT106F temperature transmitter is applied in
engineering, it needs to be configured and configured And download function blocks to complete temperature
collection and logic control. The following takes the configuration of the AI function block as an example for detailed
description. The specific configuration steps are as follows：
（1）After ensuring that the NCS-TT106F transducer block is configured correctly and are in Auto mode, open the
"Function Block Application" configuration interface in the NI software, drag the AI1, AI2, and PID function blocks
into the configuration interface to connect AI1 and AI2 OUT to PID IN and CAS_IN respectively. As shown in Figure
3.13 below.

Figure 3.14 Configuration engineering download interface
（3）After the configuration information is downloaded successfully, you need to configure the parameters in the
AI function block. Common configuration parameters are CHANNEL, XD_SCALE, OUT_SCALE, and L_TYPE. Let's take
the AI1 function block as an example for configuration, open the AI1 function block, modify the TARGET in the
MODE_BLK parameter to OOS, modify the upper and lower limits and unit parameters of XD_SCALE, modify
CHANNEL to Primary Value, modify L_TYPE to Direct, and click "Write Changes" The button finishes writing the
modified parameters. As shown in Figure 3.15.
