Overview

Our reference architecture for Embedded Data Logging is broken down into 5 levels, as seen in this diagram. Each level is made up of Function blocks that have specific features and are supported by either NI Products or third party products, as noted in the table below. You can browse through the two platform choices and then further drill into the specific model specifications, by following the product link.
