Enabling security in the connected world of Industry 4.0


Analog Devices will once again have a noteworthy presence at the Hannover Fair (Hannover Messe), with demonstrations and speaking engagements focussing on the key issues of concern to visitors to this premier event for all aspects of industrial and automation technology.

ADI, on stand H23 in hall 9 of the exhibition, will show how its position at the intersection of analogue and digital technologies, and in both the hardware and software of computing solutions, equip it to offer solutions in areas such as machine learning and machine monitoring, comprehensive connectivity - with security - and in the industrial maintenance domains with artificial intelligence.

A featured demonstration will illustrate a comprehensive approach to machine and structural health monitoring, showing how ADI’s MEMS technologies provide precision sensing, while the company’s mastery of high performance analogue-to-digital and power conversion delivers ultra low power signal processing.

'Deep signal chain', and system design, insights enable customers to extract greater value from their systems, with improved user experiences. Real time, 24-hour monitoring will be shown in both dynamic (motor) and structural (equipment mounting) contexts, comprising a methodology for complete supervision of an equipment installation.

In the closely related area of smart maintenance, ADI will show how a wireless smart multi-sensor system can be deployed for next-gen condition-based monitoring applications enabling intelligent asset maintenance. ADI’s technology releases the full potential of condition monitoring; low power signal processing components coupled with high performance sensors and compact, robust wireless communication networks represent a new paradigm in condition-based maintenance, across a wide range of industrial applications.

ADI’s demonstration will go further, exploiting the latest thinking in artificial intelligence and machine learning to make the transition from preventive maintenance, through condition-based and predictive approaches, towards true smart maintenance with work orders automatically generated by an intelligent digital assistant.

At the heart of these topics are technologies such as complete, factory- and enterprise-wide connectivity and all that goes with it, a particular concern in 2019 being cyber security. ADI will address the issue as part of a demonstration highlighting the range of solutions that the company can offer to advance Industry 4.0.

Enhanced cyber security within the factory control loop, at the edge of industrial networks will be highlighted as part of an illustration of Time Sensitive Networking (TSN) techniques, boosting security alongside features such as time synchronisation, pre-emption and control of TSN via OPC-UA.

Analog Devices’ technology not only powers interconnectivity of industrial systems, but lies at the heart of embedded applications such as motor and motion control. Comprehensive motion control synchronisation will be shown supported by real time, multi-protocol network switch technology. ADI’s mixed-signal motion control signal processing solution is a suitable base for the broadest range of servo and robotic applications.

Industrial Ethernet is the backbone of all such advancements in connectivity; the point will be reinforced in a further featured demonstration that will centre on system integration based on PROFINET protocols, together with software-defined input/output technology. Underpinned by ADI’s unrivalled knowledge of the analogue signal chain, software-defined I/O represents a family of new products offering a flexible solution for analogue and digital IO applications in a single chip solution.

Connected by Industrial Ethernet, and configured via a PLC Engineering system, this demonstration reinforces Analog Devices’ capability to provide a one stop solution for modern Industrial Ethernet field devices. This demonstration will be shown to visitors on Stand D68, Hall 9, in the PROFIBUS & PROFINET International (PI) Pavilion); and in the ODVA (the global association of automation companies) Pavilion, Stand E58, Hall 11.

Analog Devices’ staff will be on hand to answer visitors’ questions on any of the focus areas for Hannover Messe 2019 - connectivity, cyber security, machine monitoring and maintenance - or on any aspect of the company’s technology and product offering.

Extending the secure edge in industrial control
For many visitors to Hannover Messe the need to consider security is a new, and worrying, addition to their workload. Any IT system is only as secure as its weakest link.

Industry 4.0 means that the network extends to every sensor and actuator; potential points of attack exist everywhere from the edge to the core. Security-by-isolation and reliance on monitoring network traffic are no longer adequate, leading to the need to establish device level security at the edge.

Recognising these concerns, and to assist visitors seeking solutions, ADI will present a paper in the conference strand of Hannover Messe, focussing on the 'hot topic' of security in the industrial context.

To be delivered by Erik Halthen, System Security Manager at ADI, the paper will develop the theme that enabling a new industrial revolution of real time, autonomous decisions requires increased connectivity and edge computing that fundamentally changes the required approach to cyber security.
