Because implementing plant-wide systems and integrating them into the enterprise information flow is both important and increasingly prevalent, the international standards body ISA created the ISA-95 standard for enterprise/control system integration. ISA-95 can provide companies a strong starting point for this type of project. ISA-95: An Integration Standard ISA-95 Enterprise/Control System Integration has been positioned as an industry standard, describing information flows between business and plant operations functions. Developed over the past 10 years as a “multi-part set of standards that defines the interfaces between enterprise and control activities,” ISA-95 provides a reference model for MOM as part of their standard. Many of the discussions of the details within the ISA-95 standard are among engineers and IT staff, and can be very complex, which is beyond the scope of this paper. Figure 2: ISA-95 defines operations activities in a number of areas and shows information flows between those areas in this “generic activity model of manufacturing operations management.” 6 Plant to Enterprise Integration: ISA-95 is a Nice Start
What you Need to Know about ISA-95 The ISA-95 Standard comprises five levels – Level 0 to Level 4 – each representing a level of manufacturing production, from the shop floor to corporate planning. MOM occupies Level Three, as shown in Figure 1. Each level best integrates to the level immediately above or below. For example, companies that have tried hooking Enterprise Resource Planning (ERP) directly into controls and SCADA have often found that the production data is overwhelming and of limited value. Such detailed granularity will typically overwhelm an ERP database. Each level in the model is a critical component in the information architecture. The five-level ISA-95 hierarchy is not new. What is new in the ISA-95 standard are: � A simple “generic” activity model of production has been deemed to represent production control, quality, maintenance and inventory operations for all manufacturing. (See Figure 2). This model clearly shows information flows between major MOM functional areas within a production capacity, as well as flows from those areas up into the enterprise. Similar diagrams show other operational areas. � A description of data flows between the Level Four enterprise systems and Level Three MOM. The information flows out of MOM or Level Three into four major areas where the enterprise needs manufacturing data: schedule or request information, performance or response information, definition information, and capability information (see Figure 3). Figure 3: ISA-95 illustrates how manufacturing operations information flows out into four specific areas where the enterprise might need it: for scheduling or requesting information, gauging performance and seeing response, defining products, activities and resources, and reporting on capability.
