An input block is a special type of block that receives data from an external source. It converts the data into a format understandable to wires and transfers the data to the connected blocks. For example, when an input block receives a Measurement event from Cumulocity IoT, it extracts the required information from the event and then transfers the information to the connected blocks for further processing.

Models can process data from multiple devices, and scale up (using multiple cores) when doing so. For detailed information, see Model execution for different devices.

In addition, Analytics Builder supports input devices that are referred to as broadcast devices. Signals from these devices are available to all models across all devices. For detailed information, see Broadcast devices.
