This part of ISO 18435 defines an integration modelling method and its use to integrate diagnostics, capability assessment, prognostics and maintenance applications with production and control applications. The integration of other application aspects, such as security, is outside the scope of ISO 18435. NOTE 1 Other parts of ISO 18435 will define the activity domain matrix elements and the detailed integration methods between applications in the application domain integration diagram. NOTE 2 It is recognized that security is an important aspect of many applications; however, security will not be addressed in ISO 18435.
