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

Concepts such as Industry 4.0 and the Internet of Things are based around the idea of collecting all of a plant’s operating data and making it available for various applications. This data is evaluated in analysis tools, e.g., in order to detect failures in field devices at an early stage. It can also be used to optimize processes and increase productivity. However, the implementation of IoT concepts is particularly challenging in established plants, as the necessary information from the field devices is not captured in the existing automation architecture.

The User Association of Automation Technology in Process Industries (NAMUR) therefore developed the NAMUR Open Architecture (NOA). The concept described in NAMUR Recommendation NE175 extends the automation architecture without altering the existing control system. The core task of the NOA is therefore to provide information from the field level to higher-level applications in order to monitor and optimize the plant (M+O). This function can be executed by means of additional hardware and/or software. The type of data that is forwarded from the field level depends on the field devices and analysis tools used. The focus is on parameters that are to be read out cyclically, which contain information on device status or process quality.

Implementing the NOA concept with Beckhoff

How does the NAMUR Open Architecture work? Our industry experts explain the NOA concept and show how you can implement different scenarios with Beckhoff.

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

The NOA concept has a lot of potential, particularly for brownfield applications. Existing plants need to be future-proofed by converting or upgrading them: costs can be reduced and output increased by simply monitoring and optimizing plants without changing the current process control methods. Therefore, additional components are added so that the previously unused data from the field level can be collected.

The Beckhoff NOA edge device was developed for this application. Due to its compact design, it can be integrated into the established structures of the plant and saves on space. The edge device is joined to the 2-wire connection to the field device using a signal isolator, without influencing the process control.

If, in addition to data from established field devices, diagnostic data is also acquired by additional sensors, for example for vibration or temperature measurement, IP67-protected I/O modules installed directly in the field can prove incredibly useful. This version cuts down on cable routing work while also reducing the space required in the control cabinet.

The NOA concept also offers advantages for greenfield plants. For example, vital data can be transmitted directly from individual plant modules to the respective manufacturer, and the manufacturer can then provide appropriate spare parts or initiate maintenance work. This approach is particularly successful in conjunction with the Module Type Package (MTP).

Additional monitoring sensors can be installed in the plant planning stage, thus providing more data for monitoring and optimization. New technology such as Ethernet-APL makes implementation simpler, as process data and vital data can be transmitted simultaneously via the Ethernet connection. The processing and translation of the data can be implemented in the TwinCAT automation software, regardless of the protocol used.

We also offer ideal solutions for your edge device applications outside the process industry.

NOA FAQs

The NOA edge device can be flexibly expanded with additional I/O terminals until the required number of channels is reached. There is no limit to the number of field devices that can be connected. In terms of software, the data from all connected channels is made available via the OPC UA server.

No, the NOA edge device is also compatible with other communication protocols. By expanding with corresponding I/O terminals, field devices can also be connected via other protocols and flexibly combined with each other in an edge device.

The central component of the NOA edge device is an industrial PC. In addition to the NOA functionality, it can also run other software components for tasks such as condition monitoring and energy management. To do this, simply expand the I/O terminals and integrate the necessary software blocks.
