The EtherCAT Tap software application for Hilscher’s netX-based hardware provides IloT integration for new and legacy machinery. The NetField App EtherCAT Tap enables manufacturers to passively extract process data from existing machines on EtherCAT networks without impacting operations and equipment controls. This containerized software includes a built-in configuration app accessible via web browser. The extracted, raw EtherCAT data can be automatically enriched with semantics during the capture process, or manually reconstructed. Semantic information can be input via the EtherCAT network information file. After configuration, data can be sent via MQTT to the desired monitoring or analytics application. Additionally, the listen-only functionality ensures that NetField App EtherCAT Tap is secure by design.
