Tech & Buying Guide
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.
Master Acceptance Testing: Understanding FAT and SAT in Industrial Control Systems
Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) serve as critical quality assurance gateways in complex industrial control systems. Both procedures verify that programmable logic controllers (PLCs), distributed control systems (DCS), and associated field devices meet strict functional specifications. However, executing these tests effectively requires clear delineation between off-site staging and final field commissioning.
Industrial Networking Essentials: Demystifying Hubs, Switches, and Routers in Control Systems
Industrial automation relies heavily on robust networking infrastructure to connect programmable logic controllers (PLCs), distributed control systems (DCS), and human-machine interfaces (HMIs). Modern factory automation environments generate vast amounts of real-time operational data across deterministic networks. Understanding the structural differences between hubs, switches, and routers ensures optimal traffic segmentation, minimizes latency, and maintains high network availability.
