serious consequences.
Make sure that the end users read this manual and then keep the manual in a safe place for future
reference.
[Design Precautions]
WARNING
Do not write data into the "read-only area" in the buffer memory of the intelligent function
module. In addition, do not turn on/off the "reserved" signals among the I/O signals transferred
to/from the programmable controller CPU.
Doing so can malfunction the programmable controller system.
Depending on the malfunction of the external output transistor, there may be cases where the
output is on or off status. Install external monitoring circuitry for output signals that may lead to
major accidents.
CAUTION
Do not bunch the control wires or communication cables with the main circuit or power wires, or
install them close to each other.
They should be installed 100 mm(3.94 inch) or more from each other.
Not doing so could result in noise that may cause malfunction.

[Installation Precautions]
CAUTION
Use the programmable controller in an environment that meets the general specifications
contained in the CPU User's Manual.
Using this programmable controller in an environment outside the range of the general
specifications may cause electric shock, fire, malfunction, and damage to or deterioration of the
product.
While pressing the installation lever located at the bottom of module, insert the module fixing tab
into the fixing hole in the base unit until it stops. Then, securely mount the module with the fixing
hole as a supporting point.
Improper installation may result in malfunction, breakdown or the module coming loose and
dropping. Securely fix the module with screws if it is subject to vibration during use.
Tighten the screws within the range of specified torque.
If the screws are loose, it may cause the module to fallout, short circuits, or malfunction.
If the screws are tightened too much, it may cause damage to the screw and/or the module,
resulting in fallout, short circuits or malfunction.
Be sure to shut off all phases of the external power supply used by the system before mounting
or removing the module.
Not ding so may cause electric shock or damage to the module.
In the system where a CPU module supporting the online module change is used and on the
MELSECNET/H remote I/O stations, modules can be replaced online (during energizing).
However, there are some restrictions on replaceable modules and the replacement procedures
are predetermined for each module.
For details, refer to the chapter of the online module change in this manual.
Do not directly touch the conductive area or electronic components of the module.
Doing so may cause malfunction or failure in the module.

[Wiring Precautions]
CAUTION
Be careful not to let foreign matters such as sawdust or wire chips get inside the module.
They may cause fires, failure or malfunction.
The top surface of the module is covered with protective film to prevent foreign objects such as
cable offcuts from entering the module when wiring.
Do not remove this film until the wiring is complete.
Before operating the system, be sure to remove the film to provide adequate heat ventilation.
Be sure to fix communication cables or power supply cables leading from the module by placing
them in the duct or clamping them.
Cables not placed in the duct or without clamping may hang or shift, allowing them to be
accidentally pulled, which may cause a module malfunction and cable damage.
Do not grab on the cable when removing the communication or power cable connected to the
module.
When disconnecting a cable without a connector, first loosen the screws on the part that is
connected to the module.
Pulling the cable when it is still connected to the module may cause damage to the module or
cable, or misoperation due to cable contact failure.
Always ground the shielded cable for the programmable controller.
There is a risk of electric shock or malfunction.
Use applicable solderless terminals and tighten them with the specified torque. If any solderless
spade terminal is used, it may be disconnected when the terminal screw comes loose, resulting
in failure.
When wiring, be sure to verify the rated voltage of the product as well as the terminal layout. Fire
or failure may result if incorrect voltage is input or incorrect wiring is performed.

1 GENERAL DESCRIPTION
1.1 Features
The Q64TC has the following features.
(1) Optimum temperature adjustment control (PID control)
(a) The Q64TC exercises temperature adjustment control automatically by
merely setting the PID constants (proportional band (P), integral time (I),
derivative time (D)) and temperature set value (set value: SV) necessary for
PID operations.
Therefore, no special instructions are needed to perform PID control.
(b) Using the auto tuning function enables the PID constants to be set
automatically by the Q64TC.
Hence, you can use the equipment without being conscious of cumbersome
PID operation expressions to find the PID constants.
(2) 4 loops on 1 module
The module provides a maximum of four loops at the same time for temperature
adjustment control.
(3) RFB limiter function
The RFB (Reset FeedBack) limiter suppresses overshooting which is liable to
occur at a startup or when a temperature set value (SV) is increased.
(4) Sensor compensation function
By setting a sensor compensation value, the sensor compensation function
eliminates a difference between a temperature process value (PV) and an actual
temperature, if any.
(5) Connection of thermocouples compatible with JIS, IEC, NBS,
ASTM and DIN Standards
(a) The Q64TCTT(BW) accepts the following thermocouples compatible with the
JIS, IEC, NBS, ASTM and DIN Standards.
• JIS Standards : R, K, J, S, B, E, T • IEC Standards: R, K, J, S, B, E, T, N
• NBS Standards : PL II • ASTM Standards: W5Re/W26Re
• DIN Standards : U, L
(b) The Q64TCTT(BW) allows you to set the temperature measurement ranges
which meet the operating temperatures of the above thermocouples.
(6) Connection of Pt100 and JPt100 platinum temperature-measuring
resistors
The Q64TCTT(BW) allows you to set the temperature measurement ranges
which meet the operating temperatures of the Pt100 and JPt100.

1 GENERAL DESCRIPTION
(7) Choice of fine temperature measurement units and various control
temperature ranges
The temperature measurement unit of each loop can be set to 1°C or 0.1°C in
Centigrade or to 1°F or 0.1°F in Fahrenheit, enabling you to choose appropriate
resolution for control. Also, the controllable temperature range can be selected
from 0.0 to 400.0°C (when K type thermocouple is used), 0.0 to 3000.0°C (when
R type thermocouple is used) and others, enabling you to make adequate setting
for the object to be controlled.
(8) E2PROM for backing up set values
The set values in buffer memory can be stored into E2PROM for data backup.
Using the test function of GX Developer to write data directly to the buffer
memory, what is required in a sequence program is "LD " + "OUT Yn1" at the
minimum.
(9) Detection of disconnection
The Q64TCTTBW and Q64TCRTBW can detect the disconnection of a heater.
(10) Easy settings with GX Configurator-TC
Sequence programs can be reduced since the GX Configurator-TC (sold
separately) allows the Q64TC settings on the screen.
Also, the GX Configurator-CT simplifies the confirmation of the module settings
and operation status.

(2) PID control procedure
The PID control is performed in the procedure shown in Figure 1.4 below:
Read the PV value

Output MV
Import a signal from the temperature sensor and write
it to the process value storage area as a PV value.
Perform PID operation using the SV/PV values in the
set value/process value storage area.
Convert MV value obtained by the PID operation
to transistor -output on time and output it.
Fig. 1.4 PID control procedure
(3) PID control (simplified two-level response selection)
In general, when the P, I, and D constants to improve the "response to the
setting" are set, the "response to the disturbance" degrades by the PID control.
Conversely, when the P, I, and D constants to improve the "response to the
disturbance" are set, the "response to the setting" degrades by the PID control.
In the PID control (simplified two-level response selection) of this module, "fast",
"normal", or "slow" can be selected for the "response to the setting" while the P, I,
and D constants for better "response for the disturbance" are selected.
