Hi Ufuk, There is an example in the R chapter of the User Guide (available from the Help menu in Kepler 1.0.0, or from the kepler-docs subversion repository). See page 348, section 11.4.1.1.5 (Example Five: Using Ports Configured as Multiports ). Its not clear from your description exactly what you are trying to do. A multiport has multiple channels that can be written to, and the channels are represented by each connection (ie, the first connection gets channel 0, the second is channel 1, etc.). The actor decides what data is sent to each channel when writing to a multiport. If you just want to send a chunk of data to one location (e.g., actor A to Actor B), you can use an array or other token that aggregates data, or send the atomic values in sequence if you want them processed individually. If you want to broadcast the same data to multiple actors, you can use a multiport as that example shows, or use a relation in the channel to split the channel.
The Ptolemy manual has more information on multiports -- see page 170: http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII7.0/ptII7.0.1/doc/design/ptIIdesign1-intro.pdf Matt On Fri, May 29, 2009 at 3:01 PM, Ufuk Utku Turuncoglu <turuncu at ucar.edu> wrote: > Hi All, > > Is there any example actor that uses output port defined as multiport?
