Tech & Buying Guide
Engineering MCC Signal Interface Terminations in Modern Process Automation
Industrial manufacturing plants rely on Motor Control Centers (MCC) to drive critical electrical loads. Plant engineers must interface these MCC motor starters and drives with central control systems. Standardizing the Signal Interface Termination (SIT) architecture ensures seamless command delivery and feedback monitoring between field equipment and process automation platforms.
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.
