Russian, Western and Chinese PLCs in the Markets of Russia and Central Asia: The Real Situation in 2025–2026

Industrial controllers are the «brains» of any modern production facility. They manage conveyors, machine tools, pumps, and entire factories. The market for these devices in Russia and neighboring Central Asian countries is currently undergoing tectonic shifts. The familiar picture, where Siemens, Schneider Electric and Rockwell Automation dominated unconditionally, has been shattered. But it has not been replaced by a monopoly of Russian manufacturers. Instead, a new, tripolar structure has emerged: Western brands (with restrictions), Chinese brands (on the rise), and Russian brands (in a rush).

Let’s break down how this market is organized, who the main players are, and what factories from Kaliningrad to Almaty are buying.

What is an industrial controller and why can’t it be replaced by a «computer»

A programmable logic controller (PLC) is not just a computer in a metal case. It is a device built to operate in extreme conditions: vibration, dust, humidity, and wide temperature ranges. Its main difference from an office PC is determinism: it guarantees to perform a task within a strictly defined time. In manufacturing, where every millisecond of delay can lead to defects or accidents, this is critical.

A PLC collects signals from sensors, processes them according to a stored program, and sends commands to actuators. Depending on task complexity, controllers are divided into several types:

• Fixed (brick) PLCs — all in one case, cheap and reliable, for small machine tools and ventilation systems.

• Modular PLCs — a construction kit where you can expand power and add interfaces (used in large factories).

• Distributed control systems (DCS) — many controllers managing different parts of a huge plant (oil refining, chemicals).

• Industrial PCs (IPC) — powerful computers for complex calculations, robot control, or machine vision systems.

Until recently, choosing a PLC was simple: for any task there was a ready-made Siemens solution, and engineers calmly wrote programs in the TIA Portal environment. Today, everything is different.

Global context: who owns the PLC market worldwide

Before discussing Russia and Asia, we need to understand the global balance of power. On a global scale, the industrial controller (PLC) industry is a conservative, highly competitive market. It is divided among several giants whose names have become household:

• Siemens (Germany) — undisputed global leader with a share of about 30–31%, setting standards and technologies.

• Rockwell Automation / Allen-Bradley (USA) — second largest player (about 22–25%), whose equipment is the standard for heavy industry in the US.

• Mitsubishi Electric (Japan) — strong third player (12–15%), with a focus on machine tools and robotics.

• Schneider Electric (France) — fourth, known for energy management and building automation solutions.

These «whales» have for decades determined technical policy at factories worldwide, including Russia and the former USSR. Their ecosystems are not just «hardware» but closed loops of software, protocols, and services.

Russia: a tripolar market — West, China, and Russia

The Russian PLC market is one of the most interesting and complex in the world. After 2022, it experienced a shock but not a collapse. Instead, it entered a new phase that experts describe as a «new equilibrium» .

The figures are as follows: in 2025, the Russian PLC market was estimated at approximately 50 billion rubles, showing growth of 16.8% compared to 2024 and more than four times higher than 2023 levels. At the same time, according to analysts, the share of imports (including parallel imports) has stabilized in the range of 50–55% and shows no tendency to decline further. The market has not just grown — it has been radically reshaped.

Western brands: «withdrawal» in words, but not in deeds

Officially, Siemens, Schneider Electric and Rockwell Automation announced their withdrawal from Russia. In practice, their equipment continues to operate and be purchased. The reasons are obvious:

1. Huge installed base. Factories built over the past 20–30 years are literally «running» on Siemens and Schneider. Stopping them and cutting out the controllers is impossible — it would halt production. Therefore, purchases continue to support and expand existing systems.

2. Parallel imports. Despite all the difficulties, supply channels remain.

3. Engineer conservatism. Many chief specialists and design institutes are geared toward Siemens. Retraining for other hardware takes a long time and is expensive.

By the end of 2023, for example, Siemens still held 11% of the Russian PLC market in value terms, remaining the leader among all brands. This is a very telling fact: a «withdrawn» brand remains number one. Western products continue to dominate complex, high-performance, and mission-critical segments.

Chinese brands: from «temporary replacement» to strategic choice

The biggest surprise is the rapid rise of Chinese manufacturers. Initially, they were seen as a forced and temporary replacement for the departed Western giants. But by 2025, the situation had changed. Chinese PLCs have ceased to be a «replacement» and have become a full-fledged and independent choice for a significant portion of Russian enterprises.

Why did this happen?

• Price and availability. Chinese controllers are often significantly cheaper and easy to buy.

• Technology. Chinese companies (for example, global giants Delta Electronics, XINJE, and many other lesser-known brands) offer product lines for every taste and budget. In terms of performance, they are catching up with Western counterparts, and in some areas (built-in IIoT, ease of integration) they are even surpassing them.

• No sanctions. China is a friendly country, working directly and without the risk of secondary sanctions.

Experts note that Russian manufacturers are finding it increasingly difficult to compete with China, even considering the service support issues of Chinese equipment.

Russian brands: a rush and restraining factors

Sanctions have given a powerful impetus to Russian developers and manufacturers of PLCs. In a few years, they have covered a path that under normal conditions would have taken decades. A whole ecosystem of domestic solutions has formed on the market, many of which are already successfully operating in real production facilities.

• «Prosoft-Systems» (REGUL controllers) — a confident leader among Russian vendors. Their REGUL R500/R600 series controllers (successors to the ideas of Siemens S7-400) are widely used in energy, oil and gas, and critical information infrastructure (CII) facilities.

• «OVEN» (PLC200, PLC210) — the most mass-market brand. OVEN controllers on the CODESYS v3.5 platform cover tasks at the level of Siemens S7-1200. Their advantages include a huge dealer network, warehouses in Russia, and Russian-language technical support. The downside: you need to move away from TIA Portal.

• Fastwel (CPM series) — a popular solution for harsh conditions (range from –40°C to +85°C). Ideal for outdoor installations and northern regions.

• ABAK (from INCOMSYSTEM Research Center) — leader in the segment of local control systems (LCS), showed the largest relative growth in 2024–2025.

• «TREI» — good reviews for quality, wide functionality including emergency shutdown systems (ESD). Operating at over 500 oil & gas and metallurgical facilities.

• Segnetics (Matrix, SMH4) — often used in ventilation and climate control. Their main convenience is a built‑in display.

• PLC‑Elbrus — a new player based on domestic processors. This solution is for critical information infrastructure (CII) facilities requiring a high level of information security. Already used in nuclear and oil & gas industries.

At the same time, the industry is strongly hampered by dependence on foreign component bases. The chips and microcircuits needed to assemble controllers are still largely supplied from abroad. Some enterprises have even introduced internal bans on the use of foreign components, but they cannot completely replace them yet. Experts from the Association of Electronic Component Suppliers (ARPE) assess 2025 as the year of hitting the «technological ceiling».

Central Asia: a market where the West never left

While a redistribution of the market is taking place in Russia, in Central Asian countries (Kazakhstan, Uzbekistan, Kyrgyzstan) the situation is completely different. There, Western brands never left and continue to operate normally.

Official distributors work there, tenders specifying particular brands (Siemens, Schneider Electric, Mitsubishi Electric) are held, and engineers have been programming controllers in TIA Portal for decades. For example, the Kazakh company «KAZPROM AVTOMATIKA» is an official distributor of Mitsubishi Electric FA in Kazakhstan and works with global brands Siemens, Schneider Electric, ABB.

However, shifts are also beginning to appear. First, there is growing demand for cheaper Chinese analogues. Second, Russian manufacturers, having lost market share at home, have begun an active expansion into the region.

Example: in April 2025, at the «INNOPROM. Central Asia» exhibition in Tashkent, the «Rosel» holding demonstrated its PLC‑Elbrus controllers. The head of business development at INEUM named after I.S. Bruk noted: «I am confident that our controllers will be in high demand in Uzbekistan and other Central Asian countries, as they match the characteristics of leading global manufacturers. Moreover, PLC‑Elbrus is cheaper and comes with qualified service support.»

But so far these are only the first steps. Central Asia remains perhaps the last stronghold of undivided Western brand dominance in the post‑Soviet space.

Main trends and forecasts

1. The Russian market is searching for equilibrium. It will finally split into three segments: premium (Western, parallel imports), mid‑range (China and the upper echelon of Russian products), and budget (mass Russian). Further import substitution has hit a technological and component ceiling.

2. China is the main beneficiary. Chinese manufacturers have taken the niche vacated by departed Western mass‑market brands and are holding it through price and availability.

3. Russian manufacturers will consolidate. Experts forecast an inevitable wave of mergers and acquisitions (M&A) among Russian vendors. Small players will find it hard to survive alone.

4. Central Asia will become a battlefield. In the coming years, competition between Russian, Chinese, and remaining Western brands in the region is expected to intensify sharply.

5. Growth of open solutions. Sanctions pressure and the desire to escape proprietary «prisons» are pushing the market toward open protocols (OPC UA) and standardization, which in the long term will reduce vendor lock‑in.

Conclusion

The industrial controller market in Russia and Central Asia has passed a bifurcation point. The simple and predictable picture of «one brand for everything» is gone. It has been replaced by a complex, multipolar system where the customer can choose: Western reliability (even with problems), Chinese affordability and technology, or Russian sovereignty. And each of these three paths has a right to exist.
