SYSML11 — SysML: Interfaces on Flow Ports

Interfaces on Flow Ports

It’s not clear how to model complex ports that partake of both service and physical flow characteristics. For example, I could use communicate in morse code over a hydraulic line. This would be modeled normally as a standard (service) port, except for the medium.

Or I can use in-band signaling over a communication line (as it used to be on a telephone lines).

In such cases, I’d like to be able to attach interfaces (with the set of operations) to a flow port.

This is addressed in the resolution of issue 13178 by enabling blocks typing ports
to have flow properties, where the blocks can support operations and receptions
or realize interfaces that do the same.
