It is designed to help industrial and manufacturing organizations collect data from their equipment and processes, and use that data to make informed decisions about their operations. One of the key features of AWS IoT SiteWise is its ability to connect to a wide range of industrial equipment and systems, including programmable logic controllers (PLCs), sensors, and other industrial devices. It can collect data from these devices and organize it into a unified data model, making it easier to analyze and gain insights from the data. AWS IoT SiteWise also provides tools for visualizing the data, setting up alarms and alerts, and generating reports. Another key feature of AWS IoT SiteWise is its ability to scale to handle large volumes of data. It can collect and store data from thousands of devices and process millions of data points per second, making it suitable for large-scale industrial operations. Additionally, AWS IoT SiteWise is designed to be secure and compliant, with features like role-based access controls, data encryption, and integration with other AWS services for additional security and compliance features.
