PLC Programming

Most popular PLC brands

There are many PLC brands around the world that users can choose from based on their needs. Some popular PLC brands are:

Siemens
Allen-Bradley
Mitsubishi Electric
Schneider Electric
Omron

The choice of PLC brand depends on the region you're in and the industry you're working in.

So, if you're already working in a company that uses PLCs, your focus should be on the PLC brand that your company uses. Different industries prefer different brands based on their operational needs. Knowing the PLC brand your company uses allows you to focus on developing the specific skills needed for your job.

If you're not working in a company but want to start learning PLC programming on your own, you should consider the market share of PLC brands in your region. The most popular PLC brands can vary by location, and understanding which brands are most widely used in your area will help you decide which one to focus on. It can also give you access to a broader job market.

PLC brand popularity by region

Let’s compare the market share of each PLC in different regions around the world.

In North America, Allen-Bradley is the most popular PLC brand. It’s widely used in industries like manufacturing, automotive, and food processing. If you're in North America and want to learn PLC programming, starting with Allen-Bradley PLCs is a smart choice. The most commonly used Allen-Bradley PLCs are CompactLogix, ControlLogix, and MicroLogix.
In Europe, the most popular PLC brand is Siemens. Siemens PLCs, particularly the S7 series, are used in a wide range of industries, from automotive to food production. So if you’re based in Europe and want to learn PLC programming, Siemens is a great option for you.
In Asia, Mitsubishi Electric, Siemens, and Omron are popular PLC brands, especially in countries like Japan and China.
In Australia, Allen-Bradley and Siemens are the leading PLC brands, particularly in manufacturing and mining.

Each PLC has its own programming software. For example, you can program Siemens PLCs with TIA Portal. Allen-Bradley ControlLogix and CompactLogix PLCs can be programmed with Studio 5000, and to program Micro800 PLCs, you need the Connected Components Workbench (CCW) software.
