Integration² – Totally Integrated Automation from shop floor to top floor

Horizontal and vertical integration means breaking down information silos and using all the data that a company generates. We’re helping you manage the transition reliably using data.

By combining the real and digital worlds, Totally Integrated Automation (TIA) enables consistent, multidirectional data flows that allow all lifecycle parameters to be optimally coordinated. This offers vast potential for manufacturing businesses and machine and plant builders to become faster and more flexible and achieve the best possible quality while cutting down on the resources used. Scalable solution packages, the TIA Use Cases, also help implement the digital enterprise and illustrate how the challenges of the future can be overcome quickly and smoothly.

OT/IT integration

From OT to IT with TIA

To make even more comprehensive use of data and draw robust insights from it, you need high-performance data throughput and seamless data processing all the way from shop floor to the top floor. The TIA concept has an especially important role to play in this regard.

Manufacture faster, more flexibly, more securely, and at higher quality with TIA

There’s vast potential in horizontal integration at the field and machine levels and vertical integration from shop floor to top floor. Decision-makers representing plant operators and also machine and plant builders can benefit from this approach.

OT/IT integration

Using standardization to bring OT and IT networks together facilitates data-supported decision-making from the machine to the factory level. TIA provides seamless consistency and ensures that data is always up to date and available. That applies to new and existing systems alike. Machines that still lack connectivity can be retrofitted with the TIA portfolio and to realize the transparency needed for fast and accurate decision-making.

Efficient engineering

Traditional machine and plant engineering is structured sequentially: The mechanical, electrical, and automation elements follow each other, and each discipline has to wait for the preceding work to be completed. Efficient engineering using TIA, on the other hand, enables interdisciplinary and parallel work on the same project. Short, agile sprints and the use of libraries and modules reduce development time and improve quality. The same applies to automation: Continuous Integration allows several developers to work continuously on the latest PLC code, and quality is assured by a process of ongoing simulation.


From engineering to the real machine, simulation plays an important role. From simulating an initial design to a virtual prototype and simulating the engineering, the process generates a digital twin that becomes more and more detailed over time. This means machines can be virtually commissioned prior to delivery. In line integration and system design, simulation also helps optimize design, processes, and workflows – not only prior to commissioning but also during live operation, for example, before a product switchover or an expansion of production capacities.


The growth of networking in machines and systems calls for more effective protection from cyber attacks. That requires an end-to-end approach that covers all relevant levels. Based on the recommendations of the leading security standard for the industry, IEC 62443, we apply the principle of Defense in Depth, comprising the three levels of plant security, network security, and system integrity.


An important factor is the need to protect automation systems using integrated security functions: for example, secured, TLS-based communication between controllers and HMIs and a central user management system that makes it possible to assign specific access rights to each user.

TIA in practical use

TIA produces TIA – in the Lighthouse Factory Electronics Works Amberg

The Siemens Electronics Works Amberg (EWA) is not only where elements in the TIA portfolio like SIMATIC controllers are produced – the production itself is also controlled by TIA. Since 2021, Electronics Works Amberg has been named a Lighthouse Factory by the World Economic Forum (WEF), because as a digital factory it was able to increase production capacity by 140 percent despite a doubling of product complexity, with no increase in power or resource consumption.
All the components needed for a successful digital transformation are used at Electronics Works Amberg. The IIoT stack is consistent from shop floor to cloud and allows for seamless data integration from our suppliers to our customers.

The future of automation with TIA

The Siemens Electronics Works Amberg (EWA) lives and breathes the TIA automation strategy. It’s where the TIA portfolio can be said to produce itself: for example, the SIMATIC S7-1500 controllers that are manufactured there but also control the production machinery. This is digitalization and automation in perfect harmony – with many benefits that led to EWA being named a Lighthouse Factory by the World Economic Forum (WEF) in 2021. This is an acknowledgment of production facilities that are successfully implementing the Industry 4.0 strategy to become more productive and simultaneously more sustainable. In Amberg, Siemens manufactures more than 1,200 product versions and about 17 million SIMATIC products every year.
