NAMUR Open Architecture (NOA): Plant monitoring for the process industry

Beckhoff has developed an NOA edge device specifically for reading out the additional operating data for the higher-level M+O. The edge device, which consists of a compact embedded PC, EtherCAT Terminals with HART functionality, and the relevant TwinCAT project, can be placed directly in the plant.

Functions of the NOA Edge Device from Beckhoff:

independent second channel of a signal isolator is used
the widely used HART protocol is implemented for field device communication
conversion and translation of the read data
parameters are mapped onto a defined data model
standardized information models such as PA-DIM are implemented
automatic adaptation of the OPC UA information model, depending on the connected device type
