How Concurrent Software Licensing Can Benefit EMI Users

Software licensing agreements can be complicated for an enterprise. Using a multi-plant cereal maker as an example, a maker of enterprise manufacturing intelligence (EMI) software explains how concurrent licensing compares to traditional named licenses in terms of cost and administration.

Manufacturing intelligence software  bridges many gaps, enabling information to be collected and shared across many boundaries: plant floor and control room, operations and business management, etc. It also can present challenges, not the least of which is knowing which software licensing method to use to cost-effectively get everyone the information they need.

Invensys (www.iom.invensys.com) recently announced that its Wonderware Intelligence 2012 software—which collects, aggregates and contextualizes operational metrics from multiple industrial data sources in near real time—is now available with concurrent licensing, in addition to traditional named-user licensing.

“A named-user license means that that person, and that person alone, has access to the application,” explains Maryanne Steidinger, director of advanced applications product marketing for Invensys. “Concurrent licenses are used when the access to the application is done on an intermittent basis, like once or twice per shift, with multiple users needing to access a single client station or application. It is easier, and sometimes more cost-effective, to use concurrent clients vs. named users.”

Consider this example: You operate a cereal plant in California with three shifts, six days per week. You want to understand the yields of each shift, such as material going in, material coming out, percent good, percent of waste, percent of rework, number of stoppages or unplanned events, by shift. You also have another plant in Iowa producing the same cereal product, so you’d like to understand the same measures, and you’d like to compare plant-to-plant efficiencies to know which plant is doing better. Each plant has six to eight workers per shift who are responsible for the uptime, maintenance, operations, etc. They use enterprise manufacturing intelligence (EMI) software to track progress against key performance indicators (KPIs), as well as other process control software such as human machine interfaces (HMIs), batch management systems, etc.

“Because EMI is a dashboarding tool that shows KPIs, it is different from process-control- or automation-control-centric applications such as an HMI. Instead of controlling processes, it shows relationships between entities, such as energy consumption by shift, by line, by product, etc.,” Steidinger says. “This less-granular approach defines the way a customer would interact with the application, and usage is normally intermittent and ad hoc, often based on queries, much like a business intelligence application.”

The sample operation might have additional shift staff working the weekends. Because the users change, the plant needs to constantly be using the same information for operations tuning and knowledge management. “Before concurrent licensing, customers used reporting products that were flat representations of the process [to share information],” Steidinger says. “They would show output, or quality, or energy consumption, but you couldn’t get the dimensional or relationship part of the equation as you can with intelligence/EMI software. This adds a richness to the reporting and analytical capabilities of the plant, supporting more informed decisions and helping personnel understand the complexities of the plant.”

Concurrent licensing reduces the administration usually required for such multi-plant, multi-instance intelligence software deployments. It is easier to administer because IT departments do not have to monitor usage as closely. “Concurrent licensing automatically limits the number of users that can access the application at any one point to, for example, five or 10 concurrent named users,” Steidinger explains. “The software uses active directory or some type of security measure to ensure that the person logging in is that user."
