maintainability, among other benefits. Production and manufacturing industries have long employed supervisory control and data acquisition (SCADA) applications, human- machine interface (HMI) software, and other automation platforms, such as programmable logic controllers (PLCs) and process automation controllers (PACs). Progressive use of these sys- tems reduces waste, increases uptime, and im- proves overall equipment effectiveness (OEE). These systems require some level of "core" server and PC computing power to function, I ndustrial manufacturers understand that holding steady is rarely an option. This is because ongoing productivity improve- ments are a near-universal requirement. Man- ufacturers can achieve such improvements in many ways, with the most valuable upgrades enhancing several things simultaneously, per - haps across multiple levels of an organization. Today's automation experts are discovering that moving visualization and control func - tionality toward the industrial "edge" is helping them achieve better operations and improved By Jason Andersen 30 INTECH MAY/JUNE 2019 WWW.ISA.ORG Building reliable visualization and control for industrial edge applications Increase manageability, flexibility, and reliability using thin-client and virtualization architectures
