 SAFETY PRECAUTIONS 
(Read these precautions before using this product.)
Before using this product, please read this manual carefully and pay full attention to safety to handle the
product correctly.
The precautions given in this manual are concerned with this product only.
For the safety precautions of the programmable controller system, refer to the user's manual for the CPU
module used.
In this manual, the safety precautions are classified into two levels: " ! WARNING" and " ! CAUTION".
Indicates that incorrect handling may cause hazardous conditions,
resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous conditions,
resulting in minor or moderate injury or property damage.
Under some circumstances, failure to observe the precautions given under " ! CAUTION" may lead to
serious consequences.
Observe the precautions of both levels because they are important for personal and system safety.
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 any data to the "system area" and "write-protect area" of the buffer memory in the
intelligent function module.
Also, do not use any "use prohibited" signals as input or output signals from the intelligent
function module to the CPU module.
Doing so may cause malfunction of the programmable controller system.
 Due to failure of the output element or internal circuit, normal output may not be obtained
correctly. Configure an external circuit for monitoring output signals that could cause a serious
accident.
! CAUTION
 Do not install the control lines or communication cables together with the main circuit lines or
power cables.
Keep a distance of 100mm or more between them.
Failure to do so may result in malfunction due to noise.
 At power-on or power-off, a current may flow between output terminals momentarily.
In this case, start the control after analog outputs become stable.
! WARNING
! CAUTION

A - 2 A - 2
[Security Precautions]
! WARNING
 To maintain the security (confidentiality, integrity, and availability) of the programmable controller
and the system against unauthorized access, denial-of-service (DoS) attacks, computer viruses,
and other cyberattacks from external devices via the network, take appropriate measures such
as firewalls, virtual private networks (VPNs), and antivirus solutions.
[Installation Precautions]
! CAUTION
 Use the programmable controller in an environment that meets the general specifications in the
user's manual for the CPU module used.
Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of
the product.
 To mount the module, while pressing the module mounting lever located in the lower part of the
module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the
module until it snaps into place.
Incorrect mounting may cause malfunction, failure or drop of the module.
When using the programmable controller in an environment of frequent vibrations, fix the
module with a screw.
 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.
Tighten the screws within the specified torque range.
Undertightening can cause drop of the screw, short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or
malfunction.
 Shut off the external power supply (all phases) used in the system before mounting or removing
the module.
Failure to do so may result in damage to the product. A module can be replaced online (while
power is on) on any MELSECNET/H remote I/O station or in the system where a CPU module
supporting the online module change function is used.
Note that there are restrictions on the modules that can be replaced online, and each module
has its predetermined replacement procedure.
For details, refer to the relevant chapter in this manual.
 Do not directly touch any conductive parts and electronic components of the module.
Doing so can cause malfunction or failure of the module.

A - 3 A - 3
[Wiring Precautions]
! CAUTION
 Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter
can cause a fire, failure, or malfunction.
 A protective film is attached to the top of the module to prevent foreign matter, such as wire
chips, from entering the module during wiring. Do not remove the film during wiring. Remove it
for heat dissipation before system operation.
 Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be
pulled, resulting in damage to the module or cables or malfunction due to poor contact.
 When disconnecting the cable from the module, do not pull the cable by the cable part. For the
cable connected to the terminal block, loosen the terminal screw. Pulling the cable connected to
the module may result in malfunction or damage to the module or cable.
 Individually ground the FG terminal and shielded cables of the programmable controller with a
ground resistance of 100 or less.
Failure to do so may result in electric shock or malfunction.
 After wiring, attach the included terminal cover to the module before turning it on for operation.
Failure to do so may result in electric shock.
 Use applicable solderless terminals and tighten them within the specified torque range.
If any spade solderless terminal is used, it may be disconnected when the terminal screw comes
loose, resulting in failure.
 Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly.
Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire or
failure.

A - 4 A - 4
[Startup and Maintenance Precautions]
! CAUTION
 Do not disassemble or modify the modules.
Doing so may cause failure, malfunction, injury, or a fire.
 Shut off the external power supply (all phases) used in the system before mounting or removing
the module.
Failure to do so may cause the module to fail or malfunction.
A module can be replaced online (while power is on) on any MELSECNET/H remote I/O station
or in the system where a CPU module supporting the online module change function is used.
Note that there are restrictions on the modules that can be replaced online, and each module
has its predetermined replacement procedure.
For details, refer to the relevant chapter in this manual.
 After the first use of the product, do not mount/remove the module to/from the base unit, and the
terminal block to/from the module more than 50 times (IEC 61131-2 compliant) respectively.
Exceeding the limit of 50 times may cause malfunction.
 Do not touch any terminal while power is on.
Failure to do so may cause malfunction.
 Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the terminal screws or module fixing screws.

1 OVERVIEW
1 OVERVIEW
This manual describes the specifications, handling, wiring, and programming of the
loop control module Q62HLC (hereinafter abbreviated as Q62HLC) that is used with
the MELSEC-Q series programmable controller CPU.
(1) About Q62HLC
(a) The Q62HLC is intelligent function module for the continuous proportional
control.
The Q62HLC converts analog input from various external sensors
(temperature, humidity, pressure, and flow rate) into a measured value (16-bit
signed binary data), performs PID operations to attain the target set value,
and outputs the calculated manipulated value to external operation devices
with current output.
(b) The Q62HLC has the following five control functions.
• Normal control (Normal control mode)
• Program control (Program control mode)
• Cascade control
• Manual control (Manual control mode 1)
• Manual control (Manual control mode 2)
(c) The Q62HLC automatically sets the proportional band (P), integral time (I),
and derivative time (D) for PID operations using the auto tuning function.
(d) Thermocouples (K, J, T, B, S, E, R, N, PLII, and W5Re/W26Re type) and
sensors compatible with the input ranges of micro voltage, voltage, and
current can be connected to the Q62HLC.

1 OVERVIEW
1.1 Features
The Q62HLC has the following features.
(1) High speed PID control
The Q62HLC is an intelligent function module that performs the continuous
proportional control.
With the Q62HLC, the high speed sampling cycle (25ms), analog input
(thermocouple, micro voltage, voltage, and current) with high accuracy and
resolution, and the current output are available.
This enables the control that requires high-speed response, such as the high-
speed rising and falling temperature control, pressure control and flow rate
control.
(2) Optimum PID control
(a) The Q62HLC automatically performs PID control by setting the PID constants
(proportional band (P), integral time (I), derivative time (D)) and the set value
(SV) required for PID operations.
No special instruction is required to perform PID control.
(b) Five control functions are available for the Q62HLC. The Q62HLC can select
the most suitable control function for the control target.
1) Normal mode (Normal control mode)
: The Q62HLC controls the control target using the manipulated values
calculated in PID operations as the control output.
2) Program control (Program control mode)
: The Q62HLC changes the set values automatically and performs the
control, following the set program pattern. The manipulated value
calculated in PID operations is used as the control output.
3) Cascade control
: The Q62HLC performs the control using the channel 1 as master and the
channel 2 as slave.
4) Manual control (Manual control mode 1)
: The Q62HLC controls the control target using the numerical value written
in the manual output setting (-5.0 to 105.0%) as the control output.
5) Manual control (Manual control mode 2)
: The Q62HLC controls the control target using the numerical value written
in the manual output setting (0 to 4000) as the control output.
This mode is for the simplified analog I/O function.
(c) The Q62HLC automatically set PID constants by using the auto tuning
function in normal control mode.
This enables the use of PID constants without considering cumbersome PID
operation expressions (refer to Section 3.2.1).

(3) Connection of thermocouples compatible with JIS, IEC, NBS and
ASTM Standards
(a) Thermocouples compatible with the JIS, IEC, NBS, and ASTM Standards can
be connected to the Q62HLC.
• 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
(4) Connection of sensors compatible with the input ranges of micro
voltage, voltage and current
Analog input of the following ranges can be measured using the micro voltage,
voltage, and current input sensors.
• Micro voltage : 0 to 10mV, 0 to 100mV, -10 to 10mV, -100 to 100mV
• Voltage : 0 to 1V, 1 to 5V, 0 to 5V, 0 to 10V, -1 to 1V, -5 to 5 V, -10 to 10V
• Current : 4 to 20mA, 0 to 20mA
(5) RFB limiter function
The RFB (reset feed back) limiter suppresses overshooting that may occur at a
start-up or when the set value (SV) is increased (refer to Section 3.2.4).
(6) Sensor compensation function
By setting a sensor compensation value, a difference, if any, between the
measured value (PV) and actual temperature, humidity, pressure, flow rate, or
others can be eliminated (refer to Section 3.2.5).
(7) Program control function
The control can be performed automatically, changing the set value (SV) and PID
constants (proportional band (P), integral time (I), derivative time (D)) by setting a
program pattern (refer to Section 3.2.12).
(8) Cascade control function
The cascade control can be performed using the channel 1 as master and the
channel 2 as slave (refer to Section 3.2.13).
(9) Scaling function
The scaled measured value (PV) can be automatically stored in the buffer
memory (refer to Section 3.2.14).
(10) Simplified analog I/O function
The Q62HLC can be used as a simplified thermocouple/micro voltage input
module, analog-digital conversion module, or digital-analog conversion module
by monitoring the measured value and setting the manipulated value manually
(refer to Section 3.2.17).
(11) Auto tuning mode setting function
The auto tuning mode according to a control target can be specified by setting
AT differential gap and AT additional lag (refer to Section 3.2.2).

(12) Online module change function
The Q62HLC can be replaced without the system being stopped (refer to
Chapter 7).
(13) Storing setting values in FeRAM
The setting data in the buffer memory can be stored into FeRAM for backup.
When the data is directly written to the buffer memory using the test functions of
GX Developer, the sequence program required is only "LD " + "OUT Yn1"
(refer to Section 3.2.9).
(14) Easy settings with GX Configurator-TC
The number of sequence programs can be reduced by using GX Configurator-
TC (sold separately) because the settings for the loop control module can be
configured on the screen.
In addition, the setting status and operating status of the module can be checked
easily with GX Configurator-TC.
