ISA的S95 Enterprise标准是Golden基准（侧边栏）

“To me, S95 is fundamentally a requirement specification for what people have traditionally labeled ‘MES,’ “ Unger says. The standard specifies interfaces to the business and logistics levels. It also specifies interfaces to control levels, typically programmable logic controllers (PLCs) and distributed control systems (DCSs). These specifications are needed in the level between automation and business systems, Unger relates.

“Functionality is related to the definition, resource management, scheduling, dispatching and execution management, data collection, analysis and tracking of activities related to production, quality, maintenance and inventory,” explains Unger. Other topics covered in less detail include security; document, information and configuration management; and management of incidences and deviations.

第1部分和第2部分S95地址信息的交换among business and manufacturing systems, and formally define the meaning of information, says industry consultant Dennis Brandl, at BR&L Consulting, Cary, N.C., who is the ISA SP95 committee’s editor. Those two parts have also been approved as International Electrotechnical Commission (IEC) standard 62264-1 and 62264-2, respectively, says Brandl, who is also convener of Joint Working Group (JWG) 15, Enterprise Control System Integration, sponsored by IEC and the International Organization for Standardization (ISO). Its goal is to convert S95 to an international standard.

即将到来的是S95的四个部分。第3部分将是制造业务的模型。Brandl认为，它应该在明年初官方提供。他解释说，它解决了边界问题，并定义了在制造或商业物流系统的控制下需要有哪些功能。“我认为这是一个非常大的问题。这是在尝试实施制造操作系统时需要解决的第一个问题。“

Parts 4, 5 and 6 will be, respectively, object models of manufacturing operations; business-to-manufacturing operations; and, likely, manufacturing-to-manufacturing operations.

Brandl notes that the original definition of MES was not broad enough to cover the full range of manufacturing activities. But Part 3 is sufficiently broad. “End-users are using it now to build their requirement specifications for manufacturing operations.”
