Choosing the right PLC can be overwhelming for most people. If you’ve been tasked with determining what control solution is needed for your next application, a control system integrator (CSI) can be an excellent resource. A CSI should be technology agnostic. Their priority should be to understand your specific technical and commercial requirements.

1. TOP 10 MOST POPULAR PLC BRANDS
BY JUST ENGINEERING

2. INTRODUCTION
PLC (Programmable Logic Controller) is an electronic solid-state device that can control a
process or a machine and has the ability to be programmed or reprogrammed quickly
according to the demand of the application.

3. It was invented to replace the relay-based sequential circuits that were necessary for machine control. The PLC
works by monitoring its inputs, and depending on its status, activating and deactivating its outputs.
PLCs are used in many applications:
● Parts machining
● Packaging machines
● Material handling
● Automatic assembly
● Petrochemical / Chemical
● Mining
● And in general, any type of application that requires electrical controls can use a PLC.

4. TOP 10 PLC BRANDS
1. ABB
ABB's automation devices deliver solutions with high performance and flexibility to be effectively
deployed within diverse industries and applications including water, building infrastructure, data
centers, renewable energy, machinery automation, material handling, marine and more.

5. 2. Allen Bradley
Allen-Bradley is the brand-name of a line of factory automation equipment, today owned by
Rockwell automation. The company, with revenues of approximately US $6.4 billion in 2013,
manufactures programmable logic controllers PLC, human-machine interfaces, sensors, safety
components and systems, software,drives, and drive systems, contractors, motor control
centers, and systems of such products. Rockwell Automation also provides asset-management
services including repair and consulting.

6. 3. Siemens
Siemens is a global innovator focusing on digitalization, electrification and automation for the
process and manufacturing industries, and is a leader in power generation and distribution,
intelligent infrastructure, and distributed energy systems.
Siemens Corporation is a U.S. subsidiary of Siemens AG, a global powerhouse focusing on
the areas of power generation and distribution, intelligent infrastructure for buildings and
distributed energy systems, and automation and digitalization in the process and
manufacturing industries.

7. 4. Honeywell
Also one of the most popular PLC brand, Honeywell MasterLogic PLC (ML200) is a
programmable logic control system (PLC) compliant to IEC 61131. With a compact footprint
and high speed 42ns/step processor, Masterlogic PLC is suited to fast, discrete sequential
control applications in a cost effective design.

8. 5. Mitsubishi
Mitsubishi Electric’s controller line is one of the widest in the industry. Our offering spans from
our Alpha Simple Application Controller with as little as six I/O points, all the way to the high-
end Q Series Automation Platform capable of running entire plants with thousands of I/O. Our
controllers are complemented by a comprehensive array of software tools and networking
technologies. Offering seamless integration to our other automation products such as VFDs,
motion control and HMIs, to provide a comprehensive solution with the controller at the center.

9. 6. Yokogawa
Yokogawa provides, Live Logic Analyzer, a near real-time logic analysis function, gives the
programming tool the ability to display data that shows the status of a PLC program as it runs
on a sequence CPU module. This improves work efficiency by enabling engineers to monitor a
program's execution status while they collect the program execution data. At any one time the
tool can display control data for up to 96 points.

10. 7. Toshiba PLC
Toshiba PLCs are at the core of any Toshiba control system. Toshiba PLCs offer
comprehensive automation solutions highlighted by the V200 Series Micro PLCs, the V2000
Series Small PLCs and Operator Interface Stations. Applications range from simple sequence
control to large process and automation systems.

11. 8. General Electric
General Electric is also one of the most popular Plc brands that provides solutions like PSC
Parts Super Center can help identify the PLC renewal parts you need. We offer new OEM parts,
in some cases we can provide factory certified remanufactured or repair options available to
help keep your equipment running.

12. 9. Omron
Omron, a Japanese company provides 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 such as those in the CJ1, CS1 and
other series.

13. 10. Schneider Automation
This brand is well known for Modicon PLCs (Programmable Logic Controllers) and PACs
(Programmable Automation Controllers) that controls and monitors industrial operations in a
sustainable, flexible, efficient and protected way. Their PLCs and PACs supply edge technology,
augmenting it with Ethernet connectivity, built-in cybersecurity, and processing power needed
to handle Big Data analysis and protect against new vulnerabilities among connected industrial
assets, across devices or into the cloud.

14. Conclusion
PLC gives you the ability to control practically anything. As programmed intelligence, a
controller runs by itself with no need for commands from the SCADA system or local HMI.
Changing priorities or schedules on HVAC equipment, or performing automatic throw-over
(ATO) on electrical switchgear are just a few examples.
Choosing the right PLC can be overwhelming for most people. If you’ve been tasked with
determining what control solution is needed for your next application, a control system
integrator (CSI) can be an excellent resource. A CSI should be technology agnostic. Their
priority should be to understand your specific technical and commercial requirements.
