When Y function selection is set to “Immediate Output”, Y10000-Y10005 (#1 module as an example) can
used to control Y0-Y5 output on the module like a normal digital out. Set to “Channel Enable” for run PID
control of the extension module of the first channel, turning ON Y10000 (channel 1, #1 extension module as
an example) with a bit (X, M, T).
The auto-tuning trigger signal, when set to 1 , enters the auto-tuning secuence.
After the self-tuning is finished, the PID parameter value and the temperature control cycle value are automatically updated, and the
Self-tuning control bit is automatically cleared to 0. The user can also display its status. A force to 1 means that the self-tuning is in progress, and a
control bit force to 0 , means that the self-tuning is not in progress or the self-tuning is finished.

The digital output value takes the value range 0,.._4095 (12 bit resolution). In the case of PID output force analog quantity
PID output value control (such as steam lift or controllable flow angle), the output value can be sent to the analog quantity output module
（the resultation of (analog output current or voltaje) to supply the control requirements.

If the current PID control cannot meet the control requirements well, the user can also
value (P、I、D) directly write the empirical PID parameters, the module perform PID control according
to the PID parameters set by the user.
PID The PID algorithm works within ±Diff °C range with no fixed temperature. In a temperature controlled environment, when the

Temperature (Sampling temperature value + temperature deviation value δ)/10 = display temperature value. At this
deviation value δ time, the channel temperature display values can be equal or as close as possible. This parameter is
(unit0.1℃) a signed number, the unit is 0.1°C, and it will be held when power off.
Set Temperature value
The target temperature value of the control system. The adjustment range is 0~1000°C, and the precision is 0.1°C.
（unit 0.1℃)
Temperature cycle The control cycle adjustment range is 0.5 seconds to 200 seconds, and the minimum precision is 0.1 seconds. The written value is 10
（unit 0.1 sec) for actual temperature control, that is, 0.5 second control period needs to be written into 5, and 200 second control period needs to be
written into 2000.

Calibrate the ambient When the user thinks that the ambient temperature value is inconsistent with the temperature value displayed by the module
temperature value channel, the known ambient temperature value can be written into this parameter. At the moment when the module is written,
(actual temperature the temperature deviation value δ is calculated and saved. Calculation of temperature deviation value δ = calibration ambient
correction value, unit

0.1°C)
For example: in the heat balance state, the user measures the ambient temperature as 60.0°C with a mercury thermometer, and
the displayed temperature is 55.0°C (corresponding to the sampling temperature 550), and the temperature deviation value is
δ =0. At this time, the user writes 600 to this parameter, and the temperature deviation value δ is recalculated as 50 (5°C), so
the displayed temperature = (sample temperature value + temperature deviation value δ)/10=60°C.

Note: When the user enters the calibration temperature value, confirm that it is consistent with the ambient temperature. This
data is very important, once it is entered incorrectly, it will cause a serious error in calculating the temperature deviation value
δ, which in turn will affect the displayed temperature.
Output during auto-tuning, in % force unit, 100 means 100% of duty ratio force scale output, 80 force

output amplitude 80% of the degree output.
Note: When the "Y function selection" is set to "immediate output", only the channel
display temperature value, temperature deviation value δ and calibration are valid among
the above parameters, and other parameters are ineffective.

Note:
(1) The "FROM TO data initialization" function requires the module to be XD-E6TC-P-H and XD-EnTC-P with firmware version V10 or
V104 and above; this function can restore the parameters in the above table to factory settings. It is necessary to set K61 or K21 to 1, and
other values are invalid.

(2) The module can automatically save the set temperature value, PID parameters, temperature control cycle, output amplitude, temperature
deviation and temperature calibration parameters. When writing the above parameters, you need to use the rising edge to trigger the writing.
Do not write all the time. It is recommended to only write the parameters used. It is not recommended to write the data in the whole chip for
the convenience of programming, because writing 0 to some addresses will cause the system to fail. Work.

(3) Self-tuning enable address K0: The K0 address will occupy a continuous 8-bit address space, the 6-channel module enable bit
corresponds to the first 6-bit address space, and the last 2-bit address is free (but cannot be used for other purposes). When reading and
writing the enable bit, K0 can be a coil or a register. If it is a coil, it will take the coil as the starting address to occupy 8 consecutive bits; if
it is a register, it will occupy this register.
For example: to set the first and third channels of the module as self-tuning mode, and the other 4 channels as manual PID mode, when the
command is [To K10000 K0 KI M10], M10 and M12 should be set to ON. M11, M13, M14, M15 Set it to OFF;
When the instruction is: [To K10000 K0 K1 D100 ], D100 register should be assigned a value of 5 (binary value is 0101).

17-6. Wiring
⚫ When making wiring connections, pay attention to the following two aspects:
⚫ When connecting +24V power supply externally, please wiring the OV of the external power
supply with the 0V of the 24V power supply off the PLC unit.
⚫ Try to avoid interference, and take shielding the thermocouples before wiring the
signals.

2) Outputs wiring

⚫ Output terminal: Transistor output terminal, please choose DC 5V-30V power supply.

• Circuit isolation: The internal circuit of the programmable controller and the output
transistor are optically isolated by optocouplers, and each common module is also
separated from each other.

• Response time: The time off commutation from the CPU of the extension module, to the
optocoupler, and the transistor is ON/OFF is not more than 0.2ms.

• Output current: In order to limit the temperature rise, please use 50mA per point. Open
circuit leakage current: below 0.1mA.

Notes:
(1) After the auto-tuning enable is turned on, the command will immediately occupy 8 bits
of M10-M17. M10-M15 respectively correspond to the auto-tuning enable of each channel.
Which channel needs to be tuned, just turn ON the corresponding coil. M16 and M17 have no
meaning for now and need to be left blank.
(2) If the output is a solid state relay, the recommended temperature control period is
1~3s; if the output is a relay, the recommended temperature control period is 3-15s.
(3) Due to inconsistent units, the main PID of PLC unit and module PID parameters cannot be
used in common. The PID of PLC unit parameter is uppercase, and the module pid parameter is
lowercase.
The specific conversion relationship is as follows: p=P/100; i=I/10; d=D/100.
