Hi,
4diac user Marc Jakobi developed a communication library in Matlab,
which allows connecting IEC 61499 control applications with simulation models in Matlab.
The library is available as open source under the name
tcpip4diac on GitHub.
Despite its name it implements the Client/Server protocol defined in the
IEC 61499 compliance profile for feasibility demonstrations.
Therefore, it can be used for any compliant IEC 61499 like FBDK.
Best Regards,
Alois
