SCADA as a Service Explained: Cloud SCADA for Utilities

SCADA as a Service promises lower infrastructure costs, automatic software updates, and easier scalability. But unlike enterprise software, utility control systems cannot simply move everything into the cloud. Real-time control, cybersecurity, regulatory compliance, and availability requirements make SCADA fundamentally different from a CRM or ERP platform. Software as a Service means the vendor runs the software in its… Read More: SCADA as a Service Explained: Cloud SCADA for Utilities »

What Is a Communication Protocol? Rules, Types, Examples

A communication protocol is a set of rules and formats — both syntactic and semantic — that determines how two peer entities behave when they exchange data. Two devices that follow the same protocol can work together. Two devices that don’t follow the same protocol cannot communicate reliably, even if the physical connection is perfect. That definition sounds… Read More: What Is a Communication Protocol? Rules, Types, Examples »

Modbus TCP on Beckhoff TwinCAT: Client and Server Setup

If you have configured Modbus TCP on a CODESYS PLC, you might expect the same device-tree workflow in Beckhoff TwinCAT. It works differently. Although TwinCAT and CODESYS both implement IEC 61131-3 programming languages, TwinCAT uses Beckhoff’s own runtime and engineering environment. Because of that, Modbus TCP configuration is completely different from what CODESYS users expect — you will… Read More: Modbus TCP on Beckhoff TwinCAT: Client and Server Setup »

MQTT Broker Redundancy and High Availability: Complete Guide

Once your MQTT deployment matters — because it carries production telemetry, or controls physical equipment, or supports customers who expect uptime — a single broker becomes a liability. If that one broker fails, the entire system stops moving messages. For deployments where this is unacceptable, you need redundancy: multiple brokers configured so that the failure of any single… Read More: MQTT Broker Redundancy and High Availability: Complete Guide »

Modbus TCP on CODESYS PLCs: Step-by-Step Configuration

CODESYS is the runtime that powers a large chunk of the industrial PLC market — WAGO, Phoenix Contact, ABB, Delta, Eaton, Bosch Rexroth, Turck, and many more all use CODESYS underneath their own branded engineering software. The good news for anyone working with Modbus TCP on these platforms: CODESYS has native Modbus TCP support built in. No third-party… Read More: Modbus TCP on CODESYS PLCs: Step-by-Step Configuration »

IEC 61131-3: The Complete Guide to PLC Programming Languages

Every PLC vendor has its own toolchain, but they largely follow the same programming model. That’s because of IEC 61131-3. It defines the programming languages, the data types, and the software architecture that PLCs and their programming tools are built around. The goal is portability — write logic against the standard, and it should carry across platforms with… Read More: IEC 61131-3: The Complete Guide to PLC Programming Languages »
