12 ifm IoT Core
12.1 General information
The device has an ifm IoT Core software interface.
The ifm IoT core enables the user to address the device via a REST API from IT networks and to
integrate it into Internet of Things applications.
In addition, the ifm IoT Core Visualizer provides a graphical user interface to access data and services
of the ifm IoT Core via a browser.
A device description is stored on the device. This device description is a structured, machine-readable
data object in JSON format. All current values of parameters, process data, diagnostic data and
device information are mapped in this data object. These data values can be read and changed by
means of services. Moreover, services for updating the firmware and the ifm IoT Core interface and for
triggering on-demand measurements of the connected sensors are offered.
The following pages are intended to provide an overview of communication with an ifm IoT Core.
