Design Precautions ( Warning)
Please install a safety circuit to protect entire control system in case of an
unexpected power shut-down and PLC module malfunction. Such anomalies may
severely compromise the integrity of the overall system.
External to the PLC, please install circuits and switches to safeguard the system from
mechanical damages (ex. Emergency stop, upper/lower limit switches,
forward/reverse direction interlocking circuits, etc)
When the PLC detects either of the following failure conditions, it may stop
operation and turn off all outputs.
-The overcurrent protection or overvoltage protection of the power supply
module is activated.
-The PLC CPU detected a failure, such as the watchdog timer error or module
installation failure, with its self-diagnostic function.
In addition, all outputs may be turned on when there is a failure that the PLC CPU
cannot detect, such as in the relay or TR terminal. Build an extra monitoring circuit
that will monitor any output signal that could cause serious accidents.
A greater than normal current passed through the PLC for an extended period of
time, or a short-circuited load flows in the output module may cause a fire.
Build a circuit that turns on the external power supply after the PLC power supply is
turned on. If the external power supply is turned on first, it could result in output
failure or malfunction.
In order to ensure that the system operates safely, please configure an interlock
circuit in the scan program for the following situations.
-When exchanging data with computer or other devices.
-When operated by a computer or other devices.
Not doing so could result in output failure or malfunction.
Precautions for design ( Caution)
Do not bundle the input/output signal or communications cables with the main
circuit and power cables. They should be installed at least more than 100 mm
(3.94inches) apart. Not doing so could result in output failure or malfunction.

Precautions for mounting ( Caution)
Use the PLC in the environment that meets the general specifications given in this
manual. Using this PLC in any environment outside the range of the general
specifications could result in electric shock, fire, malfunction, or damage to or
deterioration of the product.
Please ensure that each module is installed correctly in its place. Loosely or
incorrectly installed pieces may result in malfunction, failure, or free-fall.
Power supply in PLC should be turned off before mounting the module. Not doing
so could cause an electric shock or damage to the device.
Install I/O devices or extension connectors correctly. If they are installed incorrectly, it
may result in an input or output failure.
Do not convey direct vibration into PLC. Not doing so could cause electric shock, fire
or malfunctions.
After wiring work, please make sure to close the terminal cover before turning on
the power for the PLC system.
Precautions for wiring ( Warning)
Make sure to check the device’s rated voltage and circuit arrangement before wiring.
Failure to do so may cause electric shock or damage on the device.
Make sure to close the terminal cover before turning on the power of PLC system
after wiring work. Failure to do so may cause electric shock.
Precautions for wiring ( Caution)
Make sure to check device’s regular voltage and sequence of terminals. Failure to do
so may cause fire, electric shock and malfunctions.
Make sure to tighten the screw with standard torque. Loose connections may cause
short, fire or malfunctions.
In grounding the FG ground terminals, be sure to conduct the product at least D
type (Class 3) grounding. Not doing so could result in electric shock or malfunctions.
When wiring, make sure that wiring debris do not enter the module. Failure to do so
may cause fire, equipment damage or malfunctions.

Total Solution for Industrial Automation
Precautions for test run and repair ( Warning)
Please do not touch the terminals when the power is ON. Doing so could cause an
electric shock or malfunctions.
When cleaning or tightening the screw, turn off the power of PLC and all other
systems. Failure to do so could cause an electric shock or malfunctions.
Do not charge, disassemble, heat up, short, or solder the battery. Doing so could
cause the battery to heat up, rupture or ignite thereby harming the user.
Precautions for test run and repair ( Caution)
Do not dissociate the PCB from the module’s casing or make any modifications to
the device. Doing so may cause fire, electric shock or malfunction.
When mounting or separating the module, make sure to turn off power to PLC and
all other devices. Failure to do so could cause an electric shock or malfunctions.
Use radio, walkie-talkie or cellphone devices at least 30cm away from the PLC. Not
doing so could result in malfunction.

3Data Memory
Data memory is largely classified into two categories: I/O memory and buffer
memory. I/O memory exchanges I/O data with the CPU through the X and Y area.
Buffer memory exchanges user data with data areas in CPU module using FROM∙
FROMP/TO∙TOP instruction.
[Figure 5] Data exchange between PWM module and CPU
3.1 I/O Memory
I/O memory is an input/output memory area which is provided by the module. This
area can be operated in the scan program. The addresses of the X and Y are
determined by the location where the module is mounted. Please refer to Appendix
2 for details. PWM output module can offer 32-pin output through the I/O memory
area. Please refer to the table in 3.1.1 to check for more details of each point.
3.1.1 Output area
An output area of digital output module outputs the value of data received from the
CPU.
•External indicator: LED (a LED per channel)
•32 Y points (Yn0 ~ Y(n+1)F) (‘n’ states a number that can be decided by
mounted in slots.

3.2 Buffer Memory
The PWM output module is equipped with shared memories inside to exchange the
data with CPU. One of these is called buffer memory, which is a collection of word
(16Bit)-unit data. This buffer memory is readable and configurable on scan program,
using FROM∙FROMP/TO∙TOP instructions. Please refer to the Appendix 1 to get
information about FROM∙FROMP/TO∙TOP instructions.
The PWM output module offers 64words of buffer memory in total. Following table

PWM Output Module User’s manual
4Functions
PWM (Pulse-Width Modulation) is a digital output that can be used as an analog
output by controlling the duty cycle that contains a certain frequency. Duty cycle is a
ratio of the ON to OFF status in 1 cycle (pulse).
[Figure 6] Definition of PWM output and duty cycle
As illustrated above, the PWM controls the output from minimum to maximum
values by changing the duty cycle of the pulse.
CIMON PWM output module can be either general digital output or PWM output.
The general digital output can be used up to 32-pin points. From these 32-pin
points, a total of 12-pin points support PWM output. Also, you can prevent drastic
change of the frequency and duty cycle by using the ramp control.

CH 4. Functions
4.1 Enable of PWM output (Buffer Memory Offset 0)
When PWM-capable points’ BIT value is set to 0, it will be possible to use them as
general output points. Similarly, if it is set to 1, it will be operated as PWM output.
The PWM output function can be enabled by using TO instruction in the buffer
memory Offset 0. Please refer to the 3.2 for information about the buffer memory.
[Table 5] Enabled points of PWM output
Example to enable PWM output of CH1, 3, 9 and output the frequency of CH1 to
1000pps and duty cycle to 50.0%.
