IT/OT - Realtime & Non-Realtime

IT and OT in Overview

Two main fields that play various but complimentary functions in modern industry are information technology (IT) and operational technology (OT). IT is the term used for technology managing and processing data in corporate processes including networks, software, and databases. Conversely, OT is the technology used to monitor and control physical devices and processes in industrial applications including manufacturing and energy supply. While IT usually handles non-real-time data, OT uses real-time processing to effectively and safely oversee manufacturing processes.

IT and OT have similarities in their aim of process optimisation and automation advancement. Though their technologies, needs, and objectives differ greatly, both systems need strong security measures and operate with data more and more.

Why Is the Subject Important?

Modern industry is progressively integrating IT and OT since businesses gain from linking the two areas. Integration can support creative business concepts and increase efficiency and production. IT and OT systems have to interact to process data in real time and control processes smoothly under rising digitalisation and the move towards Industry 4.0. This allows enhanced responsiveness to operational issues and market changes, more flexibility, and better decision-making.

Terminology Clarified

A broad spectrum of technology and systems used to process, store, transport, and manage data makes up Information Technology (IT). Important technical elements are software programs, databases, servers, and networks. Common IT protocols for network communication include TCP/IP (Transmission Control Protocol/Internet Protocol), for web data exchange are HTTP (HyperText Transfer Protocol), and for file transfers are FTP (File Transfer Protocol).

Important uses of IT include Enterprise Resource Planning (ERP) systems like SAP for managing company processes such finance, inventories, and HR. Customer Relationship Management (CRM) software like Salesforce helps organisations manage and optimise customer relationships. Large amounts of corporate data are stored and managed by databases such as MySQL, Oracle, and Microsoft SQL Server. Cloud computing platforms such as Microsoft Azure and Amazon Web Services (AWS) offer scalable storage and computing resources, enabling data and applications to be accessed over the internet.

Regarding security, encryption protocols such as SSL/TLS guarantee safe data transfer; firewalls and Intrusion Detection Systems (IDS) guard networks against unauthorised access. By providing the required infrastructure and technology, IT therefore guarantees that digital business operations execute securely, efficiently, and smoothly.

Operating technology (OT) is the term for systems and technologies used to monitor and control physical devices and processes in industrial settings. OT includes a broad spectrum of specialised tools and systems for automating, controlling, and optimising production facilities, machines, and infrastructure. Important technical elements are SCADA systems (Supervisory Control and Data Acquisition), PLCs (Programmable Logic Controllers), and DCS (Distributed Control Systems). While PLCs manage machines and automation processes locally, SCADA systems provide remote monitoring and control of processes and machines in real time. More complicated industrial sites employ DCS to offer complete control and monitoring.

Designed for communication between automation equipment and control systems, important protocols in OT include Modbus, PROFIBUS, and OPC (OLE for Process Control). In manufacturing settings, these protocols allow dependable and time-critical data transfer. Modern industrial plants are using Ethernet/IP and PROFINET more and more for machine-to-system communication.

Controlling manufacturing processes in the automotive business, monitoring power grids in the energy sector, or managing water treatment plants in utilities are all OT use cases. Designed for exceptional real-time performance, these systems allow manufacturing processes and machines to react without delay, hence guaranteeing efficiency and safety. In OT, security is concerned with safeguarding physical infrastructure from cyberattacks and illegal access using firewalls, VPNs (Virtual Private Networks), and specialised ICS cybersecurity technologies.

OT, in short, offers the required technology to track, control, and optimise industrial operations; important criteria are dependability, security, and real-time response.

IT and OT Integration Issues

The combination of IT and OT presents many difficulties. From a technological standpoint, the different systems, protocols, and standards create issues as IT and OT were traditionally created apart. OT systems are frequently not designed for networked environments, which increases cybersecurity challenges since they are more exposed to attacks on vital infrastructure. Furthermore, cultural and organisational obstacles emerge when IT and OT teams approach their work with distinct attitudes and techniques. While OT stresses physical process control and real-time response, IT concentrates on software solutions and data management, which causes communication problems and conflicting priorities.

Excursus: Non-Real-Time vs. Real-Time Requirements

A key distinction between IT and OT is in real-time vs. non-real-time needs. Operational Technology (OT) requires real-time data since industrial processes have to react right away to changes to preserve efficiency, safety, and continuity. For instance, SCADA systems have to process sensor data in real time to monitor vital infrastructure like power grids or water plants, while PLCs (Programmable Logic Controllers) have to manage machines within milliseconds for exact manufacturing. Data loss or delays can have major effects.

On the other hand, Information Technology (IT) usually manages less time-sensitive data since business operations do not need quick reactions. Where millisecond latency typically has no effect on operations, IT systems such as ERP or CRM platforms examine and store vast amounts of business data. Often, IT networks and cloud services are optimised for data throughput and security, not real-time processing. These varying needs complicate IT/OT integration especially as data flows have to be synchronised and prioritised to enable seamless communication between the systems.

One of the main difficulties in combining IT and OT is synchronising real-time and non-real-time data. To monitor and control machine operations, industrial processes, or essential infrastructure in real time, OT systems need very quick reaction times. Sensor and control data must be processed without delay; even slight latency could cause safety concerns or production halt.

Conversely, IT systems are meant to keep, examine, and offer big data sets for strategic decision-making. Many corporate operations don't need immediate replies, hence delays of seconds or even minutes are usually acceptable. The difficulty is in linking these two worlds such that real-time OT data can be securely and effectively integrated into IT systems without sacrificing performance or security.

While only pertinent data is sent to IT, Edge Computing allows real-time processing nearer to the machine. Middleware systems like Message Queues (e.g., MQTT, Kafka) can also assist in data stream prioritisation and synchronisation. Yet, maintaining steady and safe data transfer between these two quite distinct systems continues to be a major technological and organisational issue.

Why Should IT and OT Be United?

Advancing the digital transformation of industry and obtaining competitive benefits depends on IT and OT being combined. While IT manages business processes, analysis, and data processing, OT oversees physical production processes and assets. Combining both fields lets IT-driven analytics link with real-time production data, hence allowing improved decision-making, predictive maintenance and efficiency gains.

Industry 4.0* is another important motivator since it calls for close integration of IT and OT systems to produce smart and linked manufacturing processes. Faults can be found early and downtime cut by feeding machine status data straight into cloud systems or AI-driven analytics. A combined IT/OT approach improves cybersecurity since businesses can apply thorough security policies across the whole infrastructure instead of safeguarding IT and OT individually.

In the end, combining IT and OT gives businesses more flexibility and agility, hence enabling data-driven production processes to be more responsive to market needs. In highly automated industries like manufacturing, shipping, and energy, this is a vital success component.
