SCADA stands for Supervisory Control And Data Acquisition. It is a system that lets you watch and control industrial processes from one central place. It collects data from equipment in the field, shows it to operators on screens, raises alarms when something goes wrong, and sends control commands back to equipment. SCADA is common in: It is used… Read More »
Industrial Control Systems (ICS) are increasingly targeted by cyberattacks because they control critical infrastructure and physical processes. These attacks often combine IT tools, malware, and industrial knowledge to achieve their objectives. Stuxnet (2010) The Stuxnet attack was a highly sophisticated cyber operation designed to target industrial systems. It spread through infected USB drives, allowing it to bypass air-gapped… Read More »
PROFIBUS is a serial fieldbus. PROFINET is Industrial Ethernet. They share the same organization, the same application profiles, and the same GSD/GSDML device description concept — but everything underneath is different. PROFIBUS DP (CP 3/1 in IEC 61784-1) runs on RS-485 at up to 12 Mbit/s. PROFINET (CP 3/4, 3/5, 3/6 in IEC 61784-2) runs on IEEE 802.3… Read More »
In modern industrial automation, OPC UA (Open Platform Communications Unified Architecture) has become the global standard for secure and reliable data exchange between machines, software, and industrial systems. To interact with OPC UA servers, engineers use OPC UA client software. These tools allow users to browse server nodes, monitor real-time data, test connectivity, and troubleshoot communication issues. Fortunately,… Read More »
Industrial Control Systems (ICS) rely on structured network architectures to ensure reliable, safe, and secure operation of industrial processes. One of the most widely used models for designing and understanding industrial networks is the Purdue Enterprise Reference Architecture, commonly called the Purdue Model. The Purdue Model divides industrial networks into logical layers, helping organizations manage communication between operational… Read More »
Industrial Control Systems (ICS) are specialized computer systems used to monitor and control industrial processes. These systems operate critical infrastructure across industries such as manufacturing, energy production, transportation, oil and gas, and water treatment. ICS environments combine hardware, software, communication networks, and field devices to control physical operations in real time. Because they interact directly with physical processes,… Read More »
The Common Industrial Protocol (CIP) is a widely used industrial communication protocol designed for automation and control systems. It defines how industrial devices organize data, exchange messages, and manage connections in automation networks. CIP is used across multiple industrial network technologies, including EtherNet/IP, DeviceNet, ControlNet, and CompoNet. Because CIP is a media-independent protocol, it does not define physical… Read More »
Designing a SCADA network is not just about connecting devices. It is about building a system that is reliable, secure, scalable, and easy to maintain for many years. In this guide, we will explain SCADA architecture in simple and practical terms. Whether you are working on a power substation, a water utility, an oil & gas pipeline, or… Read More »
Industrial Ethernet networks are expected to operate continuously, even when cables fail or devices are powered off. In many automation environments, a short communication interruption can stop production, affect safety, or cause loss of control. To address this requirement, several standardized redundancy protocols have been developed. One of them is the Ring-based Redundancy Protocol (RRP). RRP is defined… Read More »
A Distribution Management System (DMS) is a software platform used by electric utilities to monitor, control, analyze, and optimize distribution networks. These networks typically operate at medium voltage (MV) and low voltage (LV) levels and deliver electricity from substations to end customers. In simple terms, a DMS helps utilities operate the distribution grid safely, reliably, and efficiently in… Read More »
