Siemens Industrial Automation

This article examines Siemens’ position in industrial automation from historical, technical, and future-oriented perspectives, showing how this company evolved from an electrical equipment manufacturer into a global leader in integrated automation, engineering artificial intelligence, and software-defined automation. It also explains why Siemens is considered an industrial standard choice in complex and critical projects, and under what conditions more economical options are more suitable.

Siemens is one of the most reputable and well-known brands in the world in the field of industrial automation. From oil and gas industries to steel, power plants, automotive manufacturing, and advanced production lines, Siemens equipment is recognized as a global standard.

But the main question is: Is Siemens the right choice for automation projects? To answer this, we need to examine the company’s past, current status, and future.

Siemens’ Past; The Birth of an Industrial Giant

Siemens was founded in 1847 by Werner von Siemens in Berlin. It all started with the invention of the pointer telegraph—an invention that paved the company’s way toward electrical and industrial technologies.

Entry into the Electrical Power and Equipment Industry In the late 19th century, Siemens was among the first companies to:

• Build power plants

• Create urban lighting systems

• Manufacture industrial electrical equipment

Entry into Automation The 1950s marked Siemens’ entry into industrial control. In the 1970s, with the introduction of the SIMATIC brand, Siemens entered the era of PLCs and gradually became one of the global leaders in automation.

Siemens Today; Global Leader in Automation and Digitalization

Today, Siemens is not just a PLC manufacturer; it offers a complete industrial automation ecosystem.
