Although the trend benefits production equipment commissioning, it adds complexity to qualifying a plantwide automation system. Eventually, automation engineers demanded that their automation components have plug-and-produce capabilities, the same as the production equipment. Their efforts have sought to stabilize and solidify the foundation for plug-and-produce technology. The drive for modularityOne of the groups advancing plug-and-produce technology is NAMUR, the User Association of Automation Technology in Process Industries. This international group based in Germany represents users of automation technology, including process control technology specialists.
