36 MMS January 2017 mmsonline.com DECIDING FACTORS A Focus on Data-Driven Manufacturing CO NTR I BUTO R J I M B ROW N , M a n a g e r of Co n t r o l s S of t wa r e D eve l o p m e n t , M a k i n o T he Industrial Internet of Things (IIoT) is no longer only a promise. With common data definitions for metalcutting machines specified in the MTCon- nect standard, we now have a way to easily collect large amounts of data regardless of the machine manufacturer. Development of the IIoT brings with it new requirements to control, monitor and analyze these massive amounts of data, and convert them into actionable business intelligence in real time. So, in addition to connecting machines with a standard language, manufacturers need provisions for local computing and secure networking. Major networking equipment suppliers are releasing hardware designed for long-term reli- ability in data collection and security under factory conditions. Advanced switches and other compo- nents now enable manufacturers to collect data for both local and cloud computing environments. This provides a more customizable approach to security, data storage and analysis. Fortunately, the networking equipment offers a high level of functionality and can withstand the industrial environment. These devices include What It Takes to Connect network routers and switches that can be powered by 24 volts of direct current and embedded into an industrial equipment controller. They provide the functionality necessary for secure data trans- fer to and from the equipment. Some contain the MTConnect agent, a software utility that facilitates data collection in the specified format. While most industrial equipment controllers are equipped with Ethernet capability, these are simply Ethernet ports with no data security or ability to select which devices can connect to the port for data transfer. To provide this capability, a network "smart" switch must be installed. This switch is smart in the sense that it can be programmed to allow only authorized computers to connect for data transfer with the device. It ensures the secu- rity of data collected in the machine or device. The growth of the IIoT has spurred a proliferation of Ethernet devices used in machining centers and other equipment on the factory floor. An Ethernet port enables these devices to connect with the machine controller via an Ethernet network. If an industrial device is then connected to the factory network, all of the Ethernet devices in the machine must be assigned an Ethernet address, called an IP address, on the factory network. The address makes all these devices accessible from the com- pany network and exposes them to potentially heavy network traffic. The solution to this problem is the use of a factory-hardened Ethernet router. Such a router allows definition of a network on the machine side that is not exposed to the factory network. Selected Makino's ProNetConneX IIoT interface uses a Cisco IE4000 industrial network switch to provide reliable and secure connectivity to a shop's network.
