[Design Precautions]
WARNING
●Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable controller.
Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting
operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured
external to the programmable controller.
(2) When the programmable controller detects an abnormal condition, it stops the operation and all
outputs are:
• Turned OFF if the overcurrent or overvoltage protection of the power supply module is
activated.
• Held or turned OFF according to the parameter setting if the self-diagnostic function of the CPU
module detects an error such as a watchdog timer error.
All outputs may be turned ON if an error occurs in a part, such as an I/O control part, where the CPU
module cannot detect any error. To ensure safety operation in such a case, provide a safety
mechanism or a fail-safe circuit external to the programmable controller. For a fail-safe circuit
example, refer to "General Safety Requirements" in the MELSEC iQ-R Module Configuration
Manual.
Outputs may remain ON or OFF due to a failure of a component such as a relay and transistor in an
output circuit. Configure an external circuit for monitoring output signals that could cause a
serious accident.
●In an output circuit, when a load current exceeding the rated current or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
●Configure a circuit so that the programmable controller is turned ON first and then the external power
supply. If the external power supply is turned ON first, an accident may occur due to an incorrect
output or malfunction.
●For the operating status of each station after a communication failure, refer to manuals relevant to the
network. Incorrect output or malfunction due to a communication failure may result in an accident.
●When connecting an external device with a CPU module or intelligent function module to modify data
of a running programmable controller, configure an interlock circuit in the program to ensure that the
entire system will always operate safely. For other forms of control (such as program modification,
parameter change, forced output, or operating status change) of a running programmable controller,
read the relevant manuals carefully and ensure that the operation is safe before proceeding. Improper
operation may damage machines or cause accidents.
●Especially, when a remote programmable controller is controlled by an external device, immediate
action cannot be taken if a problem occurs in the programmable controller due to a communication
failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions
to be taken between the external device and CPU module in case of a communication failure.

[Design Precautions]
[Design Precautions]
[Security Precautions]
WARNING
●Do not write any data to the "system area" and "write-protect area" of the buffer memory in the
module. Also, do not use any "use prohibited" signals as an output signal from the CPU module to
each module. Doing so may cause malfunction of the programmable controller system. For the
"system area", "write-protect area," and the "use prohibited" signals, refer to the user's manual for the
module used.
●If a communication cable is disconnected, the network may be unstable, resulting in a communication
failure of multiple stations. Configure an interlock circuit in the program to ensure that the entire
system will always operate safely even if communications fail. Failure to do so may result in an
accident due to an incorrect output or malfunction.
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.
●During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from OFF to ON.
Therefore, use a module that has a sufficient current rating.
●After the CPU module is powered OFF and ON or is reset, the time taken to enter the RUN status
varies depending on the system configuration, parameter settings, and/or program size. Design
circuits so that the entire system will always operate safely, regardless of the time.
●Do not power OFF the programmable controller or reset the CPU module while the settings are being
written. Doing so will make the data in the flash ROM undefined. The values need to be set in the
buffer memory and written to the flash ROM again. Doing so also may cause malfunction or failure of
the module.
●When changing the operating status of the CPU module from external devices (such as the remote
RUN/STOP functions), select "Do Not OPEN in Program" for "Open Method Setting" in the module
parameters. If "OPEN in Program" is selected, an execution of the remote STOP function causes the
communication line to close. Consequently, the CPU module cannot reopen the line, and external
devices cannot execute the remote RUN function.
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.

1.1 Control Mode Selection Function
A control mode can be selected using this function. This section describes control modes that can be selected for the
temperature control module.
Standard control, heating-cooling control, position proportional control
There are three types of control modes in the temperature control module: Standard control, heating-cooling control, and
position proportional control.
■Standard control
The control method is either one of heating (reverse action) or cooling (direct action). When the control method is heating, of
a heater for example, cooling is controlled by simply turning OFF the heating. When the control method is cooling, of cold
water for example, heating is controlled by simply turning OFF the cooling.
■Heating-cooling control
The control method is both heating and cooling. To heat up the target subject, its heating mean is turned ON, and its cooling
mean is turned OFF. To cool down the target subject, its heating mean is turned OFF, and its cooling mean is turned ON.
■Position proportional control
The control method is either one of heating (reverse action) or cooling (direct action). Fluid flow is controlled with an
electricoperated valve, and the process amount of such as temperature is controlled.

1.2 Control Method
1.2 Control Method
The following control methods can be achieved by setting a proportional band (P), integral time (I), and derivative time (D).
• Two-position control
• P control
• PI control
• PD control
• PID control
In the P control or PD control, the manual reset is enabled. (Page 32 Manual Reset Function)
Two-position control
Two-position control is a control method that uses the 0% manipulated value (MV) and 100% manipulated value (MV).
Turning ON and OFF the manipulated value (MV) repeatedly makes the temperature process value come close to the set
value (SV), and the temperature is kept constant.
By the setting in "Adjustment sensitivity (dead band) setting" of "Application Setting," the chattering of
transistor outputs under two-position control can be prevented. Configure the setting for the set value (SV).
■Standard control
The module operates as follows outside the setting range of "Adjustment sensitivity (dead band) setting" in "Application
Setting."
Condition Transistor output status
The temperature process value (PV) is below the lower limit of the adjustment
sensitivity (dead band).
ON
The temperature process value (PV) is above the upper limit of the adjustment
sensitivity (dead band).
