DEX: Task Method DEX - Business Information Model

The Task Method DEX: Business overview section provided a high level overview of the business information that can be represented by this DEX. This section provides a more detailed overview of that information. A description of how to represent this information using ISO 10303-239 PLCS is provided in Task Method DEX: PLCS PSM Representation.

NOTE The information shown in the SysML Block Definition diagram in Figure 3 is intended to illustrate the type of information that can be represented by the DEX. It does not imply that all exchanges must contain all this information.

NOTE The information shown in the SysML Block Definition diagram in Figure 4 is intended to illustrate the Information needed to exchange Task Method data using this DEX.
