Quick answer: A heterogeneous industrial environment uses multiple communication protocols – such as Modbus, DNP3, IEC 60870-5, MQTT Sparkplug, and OPC DA – across devices
OPC tunneling is a method for moving OPC Classic data (DA, HDA, and AE) across a network by replacing DCOM with a single, configurable TCP/IP
Short answer: MQTT and OPC UA solve different problems, so “which one” is usually the wrong question. OPC UA is a semantic framework built for
Supervisory Control and Data Acquisition (SCADA) and Human Machine Interface (HMI) show up in the same sentence so often that many users use the terms
Hardening OPC Easy Archiver means reducing its attack surface across five layers: the Windows host it runs on, the Windows service and database accounts it
SCADA (Supervisory Control and Data Acquisition) is a category of industrial control system software and hardware that lets operators monitor and control equipment and processes
In the previous article, “OPC UA Discovery Explained: Understanding LDS and GDS,” we introduced the role of discovery services in OPC UA and compared the
Historical data is the record that proves a process behaved as required, over time, and after the fact. Regulators, auditors, and customers rarely ask what
Operational Technology (OT) environments are the backbone of critical industries such as manufacturing, energy, utilities, transportation, pharmaceuticals, and water treatment. Many of these environments rely
OPC UA made industrial systems easier to connect, configure, secure and scale. One of the improvements introduced by OPC UA is its standardized discovery mechanism.
Expose SQL Server, Oracle, and MySQL data as OPC UA nodes – no scripting, no middleware to maintain, with OPC UA-grade security built in. Every
