NI-Industrial Communications for DeviceNet software leverages the NI Scan Engine to provide powerful features such as I/O variables and function blocks.

The NI Scan Engine allows efficient access to coherent sets of data channels, such as I/O channels, using a scan that stores data in a global memory map. The NI Scan Engine also updates all values at a single rate, known as the scan period.
