IoT gateways are compact and robust industrial PCs that are suitable for stand-alone PC or DIN rail mounting in the control cabinet. These devices are installed locally at the plant/machines to temporarily store sensor and control data, buffer it in case of connection problems and pre-process it before selected data is forwarded to cloud solutions for in-depth analytics. Kontron AIS primarily relies on the Kbox-250 series to realize high-performance data integration.
