Two protocols dominate industrial Ethernet networks worldwide. Modbus TCP is the most-deployed industrial Ethernet protocol globally — running on millions of devices, embraced for its simplicity and openness. EtherNet/IP dominates the North American market and is everywhere Rockwell Automation has presence — running on the same ControlLogix PLCs that drive most US manufacturing. They both run over standard… Read More: EtherNet/IP vs Modbus TCP: Complete Comparison Guide »

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: What is SCADA? How It Works, Components & Architecture »

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: What Is an Industrial Control System (ICS)? »

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: SCADA Network Architecture Design Guide for Substations & Industry »

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: Distribution Management System (DMS): Functions, Architecture, Benefits & Standards »

An Energy Management System (EMS) is a software system used by power utilities to monitor, control, analyze, and optimize the operation of electrical power systems, mainly at the generation and transmission levels. In simple words, an EMS helps system operators keep the power system secure, stable, and economical, while ensuring electricity supply meets demand at all times. EMS… Read More: Energy Management System (EMS): Functions, Architecture, Benefits & Standards »

Commercial SCADA software costs thousands of dollars per license. For students, small plants, research labs, and proof-of-concept projects, that cost is a barrier. The good news: several free and open-source SCADA platforms now deliver real-time monitoring, alarm management, HMI design, data logging, and PLC integration — without any licensing cost. Some have no tag limits. Some run in… Read More: Best Free SCADA Software in 2026: 12 Open-Source and Free… »

Monitoring SCADA protocol traffic is essential for diagnosing field issues, validating protocol behavior, troubleshooting mapping or timing problems, and improving the reliability of industrial automation systems. Whether the system uses legacy serial-based protocols such as Modbus RTU, IEC 60870-5-101, or DNP3 Serial, or modern TCP/IP-based protocols such as Modbus TCP, IEC 60870-5-104, DNP3 TCP, or IEC 61850, having… Read More: How to Monitor SCADA Protocol Traffic (Modbus RTU/TCP, IEC-104, DNP3,… »
