Tech & Buying Guide
Layer-2 vs. Layer-3 Network Switches in Industrial Control Systems
Modern factory automation relies heavily on robust Industrial Ethernet communications. Control system engineers deploy managed Ethernet switches to connect programmable logic controllers (PLCs), distributed control systems (DCS), human-machine interfaces (HMIs), and field I/O devices. Selecting between Layer-2 and Layer-3 switching architecture directly impacts network throughput, routing capabilities, and overall cybersecurity defense in operational technology (OT) networks.
Understanding OpenTelemetry in Industrial Automation: Architecture, Observability, and Operational Benefits
Modern industrial control systems (PLCs, DCS, edge nodes) are rapidly adopting cloud-native architectures, generating vast operational data. OpenTelemetry offers an open-source framework that unifies metrics, logs, and execution traces, enabling standardized observability across industrial automation and IT systems.
Mastering Functional Safety Terminology in Industrial Automation
In modern process control and factory automation, managing operational risk is a top engineering priority. High-speed machinery, high-pressure vessels, and continuous processes present constant hazards to personnel and equipment. Modern plant operations rely heavily on functional safety strategies to mitigate these risks. This guide breaks down the essential functional safety terminology that every control systems engineer should master.
