MANUFACTURING A DIGITAL FUTURE: AVOIDING THE ROADBLOCKS TO IIOT
Summary: Hardened network的需求為
(1) embedded security
(2) Dynamic network performance tuning for realtime application delivery and reliable broadband IP connectivity.
(3) Industrial grade hardware: This network needs hardware with industrial grade form factors, hardened to operate in more extreme conditions
* Hardened industrial grade switches, which can operate in environments ranging from –40°C to +75°C, are a crucial element in a network subjected to continuous or fluctuating extreme temperatures.
* Humidity and airborne dust particles necessitate additional protection
* To withstand the greater shocks and vibrations caused by heavy machinery and vehicles, as well as greater EMI/EMC variance
(4) Security and Safety: Automatic alarms and emergency notification services should be added to the network and are critical to alerting supervisors to fires or employee injury

The Industrial Internet of Things (IIoT) is connecting the entire manufacturing enterprise, from acquiring components to manufacturing, storage and delivery—in short, it’s delivering an enterprisewide, holistic view of the entire work flow. But traditional networks present a roadblock to deployments in smart factories and connected plants. Two elements are necessary to build smart digital manufacturing:
an industrialgrade hardened network, and a realtime alarm and notification system.
When we talk about smart manufacturing, we are really talking about using the IIoT
to create a complete digital environment that gathers, exchanges, collates and enables the analysis of realtime data—from the factory floor to the back office and right along the supply chain. Not only will this environment allow manufacturing and industrial processes to become more automated, but it will enable management systems to produce actionable insights across the entire enterprise, resulting in better and faster decision making.
Bringing together controllers, sensors, IP video and wirelessenabled assets on busy
manufacturing floors or industrial sites requires a network backbone that can maintain its reliability and quality of service in the face of the heat, dust, electromagnetic interference and vibrations caused by machinery and heavy vehicles.
This is why a hardened network based on rugged components is vital to ensuring a reliable and secure manufacturing network, while being able to easily expand the network to incorporate new assets and technologies as they become available.

Built to Last: The Network Requirements
So how do you build a hardened network to support connected plants and factories?First, the switches, access points and routers must be able to offer the same capability you would find in any other advanced network—embedded security, dynamic network performance tuning for realtime application delivery and reliable broadband IP connectivity. But this network needs hardware with industrial grade form factors, hardened to operate in more extreme conditions.
FairWeather Switches Aren’t Good Enough
Outside of protected and climate controlled data centers, the campus network mustbe able to handle a much wider range of conditions. Hardened industrial grade switches, which can operate in environments ranging from –40°C to +75°C, are a crucial element in a network subjected to continuous or fluctuating extreme temperatures. Nonhardened switches in the plant or at remote locations can severely limit the reliability and life cycle of the equipment, putting operations at risk.
But temperature isn’t the only factor that can affect the network at the hardware level. Humidity and airborne dust particles necessitate additional protection, and that’s where convection cooled fanless switch models can offer greater reliability and a longer life cycle. Hardened switches are also designed to withstand the greater shocks and vibrations caused by heavy machinery and vehicles, as well as greater EMI/EMC variance.
Safety First, During and Last—There’s Now an App for That
Safety and security aren’t an afterthought in the manufacturing world, so they shouldn’t be when laying the network foundations of the connected factory. Gone are the days when the only alarm system available would sound across the factory floor and everyone would drop their tools and make for the exit. Modern manufacturing with realtime data communication needs—and indeed can have—a central alarm and notification platform that pushes out notifications accessible from apps on smart devices, as well as fixed telephony and computer stations.Safety is paramount. Automatic alarms and emergency notification services should be added to the network and are critical to alerting supervisors to fires or employee injury. A network that can collect and aggregate alarms from different subsystems to a central platform can provide the responsiveness a “smart factory” demands.
