Ethernet and wireless technologies have created a genius for the Internet of Things
Together with smart sensors and smart machines, IoT includes cloud computing, analytics, big data, mobility and general visualization. Improving business performance, productivity and asset optimization are still core goals for manufacturers to implement this technology.
In manufacturing, these goals can be achieved by collecting local data from a large number of other entities used by sensors, equipment, machines, and factory floors. Once collected, the data is then sent globally through the cloud or similar infrastructure platform to all auditing departments for analysis, optimization, and more.
The push with IoT coincide with the trend toward using Industrial Ethernet and wireless networking technologies in production environments that offer incremental benefits over proprietary automation solutions as well as helping manufacturers meet the inherent needs of IoT Data transfer requirements.
Factory floor
At the level of industrial automation, Industrial Ethernet networks have shown a continuous upward trend recently. Originally considered the best IT technology option for enterprise-class applications, Ethernet became more and more popular with its potential to scale enterprise-wide vertical and horizontal integration through a single network and its enhanced industrial performance. The network is now an essential element of the automation-level control layer, and most providers are supplying Ethernet-based control backbones. There are also a series of I / O and control level products to choose from.
Manufacturing engineers and their IT counterparts now have extensive experience in implementing the IEEE802.11 Wi-Fi wireless standard; most manufacturers have established their own best practices for use. These COTS-based wireless networks are now widely used in production operations and digital fields to support applications such as mobile devices, in-plant material handling, location tracking, security and compliance.
Most manufacturers have recognized the incremental advantages of these networks over dedicated automation networks, especially on data transmission. Both Ethernet and wireless networks offer more bandwidth than dedicated automation networks, and most rely on proven standards organizations; both have a broad customer base that ensures continued growth. Especially Ethernet, which can reliably transmit accurate data to a specific location at an accurate point in time. Many manufacturers also implement the cableless wireless technology widely to meet the challenges of process performance, reliability, efficiency and compliance.
IoT depends on production data
The enabling infrastructure behind IoT consists of smart sensors and smart machines, data transmission networks, and cloud or similar platform computing architectures that support analytics, total database management systems, and more. This infrastructure is designed to support the collection, analysis and presentation of data necessary for productivity and performance improvements, asset usage optimization, ensuring safety compliance, and incremental revenue.
One of the core beliefs behind IoT is that it currently has at least the potential to help improve the performance of devices or machine layers. On the contrary, the bigger potential of this global technology lies in the system layer. IoT also supports real-time decision-making based on real-time information, not just historical data.
Another attraction for IoT is that it facilitates enterprise-wide product, process, and process innovation. People can remotely access IoT data and analytics from PCs, laptops, tablets, consoles, smartphones, etc. to improve production processes or innovate. As an extension, many existing or future products and activities will be migrated to services provided by internal or external suppliers. This has become a reality in applications such as machine or fleet maintenance: External providers provide remote services based on local data.
face the challenge
We can think of IoT as a step-by-step change in integration technology that provides us with multi-directional access to a wide range of collaborative environments that can help deliver continuous improvements in business performance and innovation.
Migration to IoT will require manufacturers to ensure compatibility of these devices with COTS networks when specifying new sensors, machines or systems. Ethernet and wireless networks will be the cornerstone of the IoT infrastructure and, fortunately, many users have adopted these technologies extensively in their production facilities. In general, factory floor shop floor sensors, devices, machines, and systems will need to transmit data to the cloud computing platform and be able to receive real-time feedback from the analytics engine to improve their performance.
The ability to access production data through a typical tiered production architecture will be a key consideration. For such integrated, network-dependent concepts, plant floor operating safety is often the primary focus. Multi-directional access control strategies, continuous monitoring and threat prevention are all primary considerations. Many manufacturers have extensive experience in using Ethernet and wireless networks and have implemented appropriate security practices. Automation vendors are now able to supply their own firewalls and other security products, and the standard work in this area is also getting better and better. For example, many Ethernet switches support the IEEE802.1x standard to provide port-based network access control. (Viki translation)
