This Part 3 standard in the ISA-95 series defines activity models of manufacturing operations management that enable enterprise system to control system integration. The activities defined in this part of the standard are consistent with the object models definitions given in ANSI/ISA-95.00.02-2010 (IEC 62264-2 Mod) and ANSI/ISA-95.00.04-2012. The modeled activities operate between business planning and logistics functions, defined as the Level 4 functions and the process control functions, defined as the Level 2 functions of ANSI/ISA-05.00.01-2010 (IEC 62264-1 Mod). The scope of this standard is limited to: a model of the activites associated with manufacturing operations management, Level 3 functions; and an identification of some of the data exchanged between Level 3 activities.
