How to use multicasting with SysML1.2 standard ports in Rational Rhapsody

Technote (FAQ)


How do you use multicasting with SysML1.2 standard ports in IBM Rational Rhapsody?


This is not documented elsewhere.


Multicasting works in a similar way for SysML1.2 standard ports as it does with UML standard ports. Rational Rhapsody still uses the MULTICAST_GEN macro. You have two options:

  1. Add a send action and Rational Rhapsody will automatically generate the correct macro - MULTICAST_GEN

  2. Add the MULTICAST_GEN macro manually to the statechart. For Rational Rhapsody, in C this should replaced with RiC_MULTICAST_GEN_PORT

An example project is attached.
