The IT network is traditionally concerned with things like data storage, data analytics, and business applications. While these are important, they are not typically as time critical as data is referred to as the operational technology (OT) control network. Within that control network, there can be multiple different production cells or machines that often have limited ability to communicate with each other. The concept of factory network, where all devices, machines, and robots are connected and interconnected, and speak the same language. Each IP-addressable device can be communicated with in real time or of other devices on the network. Key enabling technologies for such a converged digital factory network are Industrial Ethernet, time sensitive networking (TSN), Ethernet-APL (advanced physical layer), and IO-Link. With all devices speaking the same Layer 2 language, it is now possible to control both the IT and the OT portions of the network with the same control and network management system, while the time respected. The sheer volume of both time-critical upgrades for increased bandwidth to ensure the latency-free delivery of data, which is critical to of the manufacturing plant. The convergence of OT and IT makes scalability opportunities virtually limitless.

CYBER SECURITY – THE LAYER OF SKIN PROTECTING TRUSTED DIGITAL FACTORY DATA
With increased interconnectivity comes the need for heightened data security, as smart factory environments expose people, technology, processes, and intellectual property to cyber threats. This is driving the need for features like secure boot, secure software update, secure transmission authentication, and hardware root of trust. A fundamental aspect of securing a network is the authentication of each new device attempting to connect to the network. It consists of checking that the device is genuine before authorising any network transaction with it. Like device authentication, secure boot is a must have, coming from a trusted source with public key cryptography employed to verify the digital
WHAT TECHNOLOGY SOLUTIONS ARE AVAILABLE TODAY? Analog Devices has always been valued for innovative precision technology used to sense, measure, and accurately control devices throughout the factory. Combining this with an expansive industrial connectivity and power portfolio, and additional digital capabilities, including AI expertise, ADI has the technology and domain expertise to make advanced digital factory capabilities become a reality. Low bandwidth, multichannel sigma-delta ADCs such as the AD4130 family integrate the full analogue front-end circuitry for effortless interfacing to multiple sensor types. This enables sensor fusion with advanced diagnostics to support localised fault detection and fast decision-making. The industry’s lowest power 10BASE-T1L ADIN1110 MAC-PHY and accompanying ADIN1100 PHY enable the transition to Ethernet-APL all the way to the process edge, over 1.7km of single-pair Ethernet cables. For cyber security, turnkey, hardware-based
solutions allow customers to easily integrate data security into their products. The DS28S60 and MAXQ1065 are ultra low power secure integrated circuits (ICs) that enable public key cryptography even in the most power and computational-resource constrained designs. The MAX78000 AI microcontroller enables
neural networks to execute at ultra low power, providing actionable insights from AI at the edge.
THE PATH TO THE PERVASIVE DEPLOYMENT OF THE DIGITAL FACTORY Industry surveys suggest that 85% of companies have accelerated digital transformation within their manufacturing plants in the past 2 to 3 years.3 However, full digital factory implementations are not the norm yet. The World Economic Forum’s global lighthouse network of leading manufacturers is demonstrating how digitalisation strategies and digitally infused growth. These manufacturers are capitalising on productivity improvements by unlocking capacity through the deployment of innovative technologies. These technologies accelerate favourable outcomes. This is resulting in a dual
CONCLUSION – MAKE YOUR DIGITAL FACTORY A REALITY As digital transformation continues to accelerate, factories face both opportunities and challenges. but implementing these technologies can be complex and requires thoughtful execution. Leveraging partners with deep domain
expertise is paramount to enhancing collaboration lies at the heart of the most robust and adaptable digital factories of tomorrow.
