Tech & Buying Guide
Hub vs Switch vs Router in Industrial Automation Architecture
Modern factory automation relies on reliable industrial networking infrastructure to exchange real-time field data across operational technology systems. Engineers often encounter networking hardware like hubs, switches, and routers when integrating Programmable Logic Controllers, Distributed Control Systems, and SCADA monitoring nodes. Although these devices share physical ports, they operate at different layers of the Open Systems Interconnection reference model and deliver distinct traffic management capabilities.
Marshalling Cabinet Preventive Maintenance: Essential Healthiness Checks for PLC, DCS, and ESD Systems
Marshalling cabinets serve as the vital interface between field instrumentation and control room electronics in modern process facilities. Regular preventive maintenance of these cabinets ensures signal integrity across programmable logic controllers (PLCs), distributed control systems (DCS), and emergency shutdown (ESD) networks. System technicians must execute structured inspection protocols to mitigate environmental risks, identify loose wiring, and maintain continuous operational readiness.
Spatial Computing in Industrial Automation: Elevating PLC and DCS Operations with AR and VR
Industry 4.0 integrates digital intelligence into field operations, transforming factory automation landscapes worldwide. Spatial technologies—specifically Augmented Reality (AR) and Virtual Reality (VR)—redefine how engineers interact with industrial control systems. By bridging computer-generated CAD models with real-time operational technology (OT) data, immersive displays enable intuitive monitoring, rapid diagnostics, and safer maintenance across complex processing facilities.
