2. INTRODUCTION TO OMRON PLC
(CQM1H )
• Training kit which will be studied is from OMRON
brand, model CQM1H of module types.
• A type of PLC control system and is able to control
16 input signals and 16 output signals.
• The control consists of three modules:
• Power supply modules
• Control modules
• Output modules
3. FEATURES ~
• The CPU Unit provides 16 built-in input terminals.
• I/O Units can be added to increase I/O capacity.
• The CQM1 is much faster: about 20 times faster than
P-type PCs.
• High-speed timers and counters are built in.
• Outputs are processed when instructions are
executed (direct outputs).

5. POWER SUPPLY MODULES
• Function
• 5VDC supply voltage to the unit and output
control module.
• Model
• Power supply model - PA203 CQM1
• Green indicator light will be lit when the power
supplied was 240VAC
6. CONTROL MODULES
Processing the received signal from the input (input
signal) and produces a signal that has been processed
to the output.
• Modules & unit
• Used from model CPU 21.
• Have units such as:
• Built-in input terminal,
• Built-in peripheral port,
• Built-in RS-232 port,
• Port batteries,
• Port portable memory
• memory device
• microprocessor
7. • The CQM1 is a compact, high-speed PC composed of
a Power Supply Unit, a CPU Unit, and I/O Units.
• All of these Units connect at the sides to form a single
PC, which is normally mounted to a DIN track.
• All CQM1 CPU Units, except for the CQM1-CPU11-E,
are equipped with an RS-232C port that can be
connected directly to a host computer, another
CQM1, or other serial devices.
8. CENTRAL PROCESSOR UNIT (CPU)
• Function
• Regulate and supervise all operations and execute
commands stored in memory.
• A bus system is used as a medium of information
between the CPU and other devices.
• Devices
• OMRON PLC CQM1H using microprocessor integrated
circuit as CPU
10. AREAS OF APPLICATION
• Manufacturing / Machining
• Food / Beverage
• Textile Industry
• Aerospace
• Printing Industry
11. WHY PLC'S ARE PREFERRED?
Using PLC's to achieve automation has many advantages like:
1) Consistency in manufacturing can be easily achieved.
2) Complete control of the manufacturing process can be
achieved.
3) Accuracy and quality can be improved.
4) Productivity can be improved.
5) Makes it easy to work in difficult or hazardous environment.

16. SAFETY PRECAUTION
• Do not attempt to take any unit apart while the
power is being supplied.
• Do not touch any of the terminal while the power is
being supplied.
• Do not attempt to disassemble, repair or modify any
units.
• Tighten screws on the terminal block of the AC
power supply unit to the torque specified in the
manual.
• Double check the user program for proper
execution before actually running it on the Unit.
17. ADVANTAGE AND
DISADVANTAGES
ADVANTAGES DISADVANTAGES
Fast PLC Devices Are Proprietary
Easily programmed and have an
easily understood programming
language.
Initial Costs Are High
Improves Productivity There's Too Much Work Required
In Connecting Wires
Improves Quality Unemployment Rate Increases
18. CONCLUSION
• Programmable Logic Controllers, along with easy-to-use
Support Software, are available to flexibly handle applications
from small-scale equipment to entire production lines with
Programmable Logic Controllers.
• It can be effectively used in applications ranging from simple
control like replacing a small number of relays to complex
automation problems.
