SYSML11 — 09.Ports and Flows: FlowPort, Standard Port

  • Key: SYSML11-132
  • Legacy Issue Number: 12222
  • Status: closed

  • Summary:

    Experience modelling a wide range of heterogeneous systems has proven that the representation of logical channels as information flows across connections between flowports nested within standard ports is a very useful idiom. It would help if this possibility is explicitly stated in both FlowPort, Standard Port, and illustrated in specification figures. Example: a software application acquires encoded signals representing physical positon and rotation via a high-level software API to a low-level A./D card in a computer. The software application is connected to an A/D module subject to a contract represented by an Interface provided by a standard port (subject ot a protocol). The flow of information corresponding to logical acquired channels can be well represented as flowports nested within the standard port of the A/D module. This example is illustrated in detail at: It is marked as 'significant' because without this idiom of nesting flowports on standard ports it is impossible or very difficult to model a wide range or real-world systems.
