38 MMS January 2017 DECIDING FACTORS A Focus on Data-Driven Manufacturing Ethernet addresses in the machines that need to be exposed to the factory network can be pro- grammed using a utility called Network Address Translation (NAT). Using NAT, the Ethernet address to be assigned on the factory network is translated to an address programmed into the router. Similarly, information sent from the Ethernet address pro- grammed into the router is translated out to the factory network. In this way, the Ethernet devices used in the machine controller that do not require connection to the factory network can be protected from that factory network. Manufacturers also will need IIoT solutions that combine cloud-based computing with new forms of computing to collect and analyze machine data on the factory floor. In cloud computing, data is collected and transmitted from the factory over secure networks to servers in remote locations. As IIoT solutions are implemented in more machines and industrial processes, they generate vast amounts of data that cannot be affordably trans- mitted, stored or processed. The solution is inte- grated computing, networking and storage closer to the machines. This approach, becoming known as fog computing, eliminates "latency," the tendency for data transmission and processing to slow down as a result of the excessive volume of data. Fog computing also dramatically reduces bandwidth, the capacity of the network to transmit vast amounts of machine data to the cloud. The security of a shop's machine data also is improved because sensitive information and machine controls do not have to be exposed to networks and storage devices outside the shop's systems. The emergence of factory-hardened network devices will enable manufacturers to gather, ana- lyze and make business decisions based on insights from the data on a much broader scale than ever before. To ensure this digital transformation of operations succeeds, manufacturers must consider not just what can be done, but how to connect their machines securely to the IIoT.
