IT and OT: Convergence, Digitalization, and Industry 4.0
In modern industry and technology, two terms play a central role: IT (Information Technology) and OT (Operational Technology). While IT deals with the processing, storage, and transmission of data, OT focuses on controlling, monitoring, and automating industrial processes. But what happens when these two worlds collide? In this article, we’ll take a look at IT-OT convergence, its importance for digitalization, and how it’s driving Industry 4.0 forward.

What Is IT and What Is OT?
Information Technology (IT)
IT encompasses all technologies used for processing, storing, and transmitting information. This includes servers, databases, networks, software applications, and devices like laptops or smartphones. IT is primarily found in office environments and serves to support business processes, analyze data, and enable communication within and outside a company.
Operational Technology (OT)
OT, on the other hand, focuses on controlling and automating physical processes, typically in industrial settings. This includes machines, robots, sensors, and control systems like PLCs (Programmable Logic Controllers). OT is designed to perform real-time control to ensure production processes are efficient and reliable.
The IT-OT Convergence: Why Is It Important?
IT-OT convergence refers to the growing interconnection and integration of IT and OT systems. This convergence is a key aspect of digitalization and enables companies to optimize their production processes, reduce costs, and develop new business models.
Benefits of IT-OT Convergence
-
Increased Efficiency: By linking IT and OT, production data can be analyzed and utilized in real-time to optimize processes.
-
Transparency: Companies gain better insights into their production workflows and can respond more quickly to changes.
-
Automation: The integration of IT and OT enables the automation of processes, leading to higher productivity.
-
New Business Models: By connecting machines and systems, companies can offer new services such as pay-per-use or predictive maintenance.
Challenges of IT-OT Convergence
Despite the many advantages, there are also challenges to consider when integrating IT and OT:
1. Security
OT systems were traditionally not designed to be connected to the internet or IT networks. This creates security risks, as attackers could infiltrate OT systems through IT. It’s essential to implement robust security measures to protect both IT and OT systems.
2. Interoperability
IT and OT systems often use different protocols and standards. Integrating these systems requires specialized gateways or middleware to facilitate communication. Examples of such protocols include OPC UA, MQTT, or Modbus.
3. Retrofitting
Many existing OT systems are not designed for integration with modern IT systems. Retrofitting – upgrading older systems – can be complex and expensive. Creative solutions, such as using cameras to capture analog data or converting serial protocols into digital formats, come into play here.
Industry 4.0: The Future of Production
Industry 4.0 is the result of IT-OT convergence and describes the fourth industrial revolution, where intelligent, connected systems are revolutionizing production. The goal is to make batch size 1 – the individual production of products – economically feasible.
Example: Custom Eyewear Production
Imagine you configure a pair of custom glasses online with your personal preferences. Once you place the order, the data is sent directly to the production hall, where 3D printers and grinding machines automatically manufacture the glasses. This vision of batch size 1 is made possible by the interconnection of IT and OT.
Conclusion: IT-OT Convergence as the Key to Digital Transformation
IT-OT convergence is a key driver of digital transformation in the industry. It allows companies to optimize their production processes, develop new business models, and remain competitive. However, the integration of IT and OT requires careful planning, especially regarding security and interoperability.
With Heisenware, IT-OT convergence can be made significantly easier and successful. Our entire platform is designed to meet the requirements of both IT and OT.
