Enterprise controlEnterprise control is the ability to combine control, intelligence and process management to enable business optimization that is inclusive of business and production operations. It combines the strength of both business processes and production operations processes. It is the deliberate act of synchronizing business strategy with operational execution in real-time to enable closed loop business control across an enterprise.[1] OverviewA distributed control system gave way to process automation systems which lead the way for the concept of collaborative automation process systems developed by ARC Advisory Group[2] Later, enterprise control systems became key terminology in the marketplace. ANSI/ISA-95 Enterprise-Control System Integration, or ISA-95 (known internationally as IEC 62264) is an international standard for developing an automated interface between enterprise and control systems.[3] This standard has been developed for global manufacturers. There are five levels and It was developed to be applied in all industries, and in all sorts of processes, like batch processes, continuous and repetitive processes.[4] Key elements
Interoperating enterprise and industrial service-oriented architectures (SOA) provide industrial companies with the potential for problem solutions that cover entire plants and entire industrial enterprises. This enterprise-wide system can be developed using systems and technologies previously installed. The resulting system, consisting of multiple vendor products acquired over many years working as a single system, is what is referred to as an enterprise control system.[5] The enterprise control strategy is built around the premise that manufacturing needs an enterprise control system to integrate business systems and manufacturing in real-time. The concept of the enterprise control system encompasses everything from sensors and people in manufacturing to the ERP system. An enterprise control system is the open architecture framework to integrate control systems with the enterprise while adding functions to improve business performance including MES, optimization, workflow, quality management, and asset management.[6] ISA95 “levels”Purdue Reference Model, “95” provides a model that end users, integrators and vendors can share in integrating applications at key layers in the enterprise.[7] This model influenced the ISA-95 (International Society of Automation) enterprise-control integration standards,[8] which expanded on the terms of the Purdue Reference Model and describes the interface between enterprise and control systems.[9][10]
