ISO 10303-239 Activity Model

ISO 10303-239 Activity Model Coverage

The ISO 10303-239 PLCS Application Activity Model (AAM) is an IDEF0 representation of the business activities that set the scope and information requirements for the PLCS standard. The model is composed of a set of figures and a set of definitions of these business activities and their associated information flows.

IDEFØ provides a graphical notation for function modeling of an organization or system. Activities can be described by their inputs, outputs, controls and mechanisms (ICOMs).

IDEFØ Box and Arrow Graphics

This DEX supports a subset of these business activities and information flows. These are highlighted in yellow in the figure Figure 1.

The information flows marked with an asterisk are not explicitly represented within PLCS. This information is instead transferred by other means, e.g., handled by a document.
