Hello everyone,

For my current project I am working on I need to transfer data between multiple Simulink instances running on individual PC's. The connection will be established using a TCP Connection. As the existing Receive/Transmit blocks only act as clients I need to implement Server functionality. Simulink itself (sadly) does not offer this capability. I am now trying to use this toolbox that (with some tweaks to make it compatible) seems to work fine for matlab. When I use it in the matlab command window it works just fine. Now I wanted to implement this into my Simulink model. I tried to call the pnet methods (for example

socket=pnet('tcpsocket',25000)

)the toolbox provides within a System Object but as the toolbox compiles to a mexw64 file I couldn't get it to work.

Now I wanted to ask if there would be any way to use this Toolbox in a system object or if I Need to use another approach (Matlab S-function?). Or, even better, if someone had a reliable, working, solution for TCP Server functionality in Simulink (I know about the workaround using echotcpip but I cannot use it for this case) Thanks in advance
