TAGXCAN® INDUSTRIAL GATEWAY

Overview

TagXcan® is an enterprise-grade Windows-based industrial communication gateway and telemetry platform developed by RDL Technologies. Engineered specifically for smart manufacturing, SCADA integration, and Industry 4.0 digitalization, TagXcan seamlessly bridges heterogeneous plant-floor PLCs, field devices, and instrumentation with modern enterprise IT databases, REST APIs, and Cloud MQTT brokers.

By supporting 8 native industrial communication protocols within a single unified engine, TagXcan eliminates proprietary vendor lock-in, enabling real-time centralized data collection, telemetry archiving, automated Excel reporting, and bidirectional API dispatching across shop-floor equipment.
