Tech & Buying Guide
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.
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.
