According to research firm MarketsandMarkets, from 2017 through to 2022, edge computing will experience a Compound Annual Growth Rate (CAGR) of 35.4% (from $1.47 Billion USD to $6.72 Billion). Increased load on cloud infrastructure, application environments that are not suited to the cloud due to latency issues, and the growth of digitized applications across industries are some of the main factors driving the edge compute momentum.
Organizations that invest in edge computing will need to devise modern strategies for managing these small, yet important and geographically dispersed data processing environments. The approach will be different from the way traditional, centralized data centers are managed. A large global enterprise, for example, may find itself having to manage hundreds or even thousands of these sites. Therefore, dedicating IT staff for edge support is neither practical nor affordable. These environments will require sophisticated tools that enable a very simple “lights..

In August of 2018, Modbus.org published the Modbus Security protocol. The use of secure protocols is a fundamental component in efforts to secure Industrial Control System (ICS) traffic. Secure protocols can mitigate many common cyber-attacks, including replay and man in the middle exploits.
The new protocol will provide robust protection through the blending of Transport Layer Security (TLS) with the traditional Modbus protocol. TLS was selected as it is a well-known, widely accepted internet standard. TLS will encapsulate Modbus packets to provide both authentication and message integrity protection. The new protocol leverages X.509v3 digital certificates for authentication of the server and client. The protocol also supports the transmission of role based access control information utilizing an X.509v3 extension to authorize the request of the client. Modbus Security will utilize a new port – traditional Modbus uses port 502, the new Modbus Security protocol will utilize port 802.

Optimizing guest comfort and control with a connected hotel The Evolution Lisboa Hotel, a new hotel located in Lisbon, Portugal is not only a new facility but one that runs on a world-class hotel system and modern technology. The connected hotel attracts many customers who are fortunate to experience the finest comforts with great convenience. You might wonder what that entails – get this: Guests can control their rooms through their smartphone or tablet by simply downloading an app. This control includes room settings such as lighting, curtains, temperature, and more. But it’s not only the guests that have this sort of ability, hotel managers and staff can do the same from the front desk or even remotely allowing them to monitor and control the entire building.
Managers can even access live reports and set controls based on occupancy. Rooms and areas of the hotel that are unoccupied can be partially disconnected to save energy.
“We are able, in real time and anywhere in the world, t..

When it comes to protecting people and equipment in low voltage (LV) environments, nothing is more important than having reliable circuit breakers in place. Over time, circuit breaker technology has advanced in many different ways, including becoming more intelligent and more flexible. This has allowed them to increase performance and meet a broader range of applications.
However, in extremely harsh environments, circuit breakers are faced with conditions that are especially challenging. These conditions can cause false trips or other kinds of breaker failures. In this post we’ll have a quick look at some of these situations, and the types of circuit breaker features you should look for to make sure they’re robust enough to survive any hazard. Circuit breakers that operate reliably will keep people and electrical installations protected, while operations run continuously and efficiently.
Extreme vibration risks There are many applications where circuit breakers face high vibration pr..

Thinking about building construction brings us back to the notion of processes dominated by physical labour. This is because, till the earlier times, the motive of construction was merely to erect buildings. However, in the 21st century the time has come when the construction is focused towards gaining mass support of the researchers and technology-aided design.
Building management system or building automation system have made it possible to automate operations that were done manually earlier. The functionalities added to the building nowadays were earlier a sci-fi story. The connected system can monitor, control and operate the building’s environment like ventilation, air conditioning, lighting, access control etc. This is made possible by cloud computing technology and Internet of Things that uses internet protocol to foster these operations.
These buildings are characterised by as the modern day buildings with advanced technical support. They are capable of managing security func..

The prominence of electrical systems in today’s day-and-age simply cannot be mentioned enough. The fact of the matter is that these electrical systems have gone a long way in ensuring that technology takes precedence in modern times. Without adequate safeguards to take care of said technological applications, it’s only a matter of time before this technology ends up failing society in the long run – such is their fragile nature.
Thus, a pressing need arises among the populace to be provided with optimal electrical systems that can ensure a definite level of safety in the industries and homes. Only by doing so can one actually utilise these electrical systems without worrying about the potential ramifications that can arise as a result. It also helps promote a sense of safety, since any chances of short-circuiting or something else along the same lines can be mitigated extensively, if not negated entirely.
This is where various devices come into play, that can help promote the notion ..

• Ensuring reliability, resilience and efficiency by using intelligent system components and IT/OT convergence
• Holistic approach for smart, digital substations capable of handling demands of the power grid of the future
• Environmental protection ensured by integration of eco-friendly technology
Siemens has launched the concept for substations with the future built in – an integrated 360°portfolio of products and solutions based on Siemens' unique technical know-how and consulting expertise, at this years' CIGRE session in Paris. Global trends like decarbonization, decentralization and digitalization are disrupting the energy industry.

• Vacuum interrupter unit and purified air replace SF6 as the quenching/insulating medium
• The world's first gas-insulated switchgear without SF6 for 170 kV / 50 kA
Siemens and Iljin Electric, a Korean manufacturer of electrical systems and gas-insulated switchgear (GIS), have signed an agreement to develop an SF6-free GIS for the 170 kilovolt (kV) voltage level. The technology has already been developed by Siemens for applications up to 145 kV. This GIS uses treated air, known as “Clean Air”, instead of sulfur hexafluoride (SF6) as the insulating medium. “This makes the GIS environmentally friendly and does not require any special precautions to be taken during manufacturing, operation, and recycling. The GIS can also be used at extreme temperatures, and there is no need to report the quantities of fluorine gas used.”, explains Ralf Christian, CEO of the Siemens Division Energy Management.

We’ve seen lithium-ion battery adoption grow at a rapid rate over the last couple of years. In fact, Bloomberg New Energy Finance report forecasts that 40% of data center battery backup will be lithium-ion by the year 2025. Among hyperscale data centers, this forecast is even greater at 55%. We know valve regulated lead acid (VRLA) is a less expensive battery solution on day one, so what’s driving this rapid growth for lithium-ion?
Lithium-ion Capex Costs Continue to Decline There have been significant improvements with chemistries and technologies of lithium-ion batteries that have made them appealing for UPS applications. The Electrical Voltage (EV) industry is largely to thank for these advances. As adoption grows and the technology continues to mature, costs per kWh are declining. They still have a higher capex than VRLA batteries, but only by a factor of 1.5x to 2x today.
So still, we asked what’s the main reason for lithium-ion adoption? TCO savings. The Data Center Science Cen..
