I have been sending a command matrix from a MATLAB GUI to a simulink model running in standalone mode on a Speedgoat. I did this using the simulink blocks attatched. Then in my GUI I create a TCP client with tcp = tcpclient('192.168.7.5',5027);. I can then write my data with write(tcp,data);. For the next project however I need to communicate Speedgoat to Speedgoat via TCP. I used the simulink blocks TCP Server in one model and TCP Client in the other. This built fine but when I went to the MATLAB command window to create the TCP Server object with, t = tcpserver(IP address, port), so I can write and read data from them it says I need "Instrument Control Toolbox". It seems odd that I can create a client object fine but not a server. The blocks compiled so I'm assumming my Server and Client exist I just need to enable them. Is there a way I can do this without buying the "Instrument Control Toolbox" or must I buy it for Simulink to Simulink communication via TCP.

The tcpserver function is only available in Instrument Control Toolbox. However, you could use the tcpclient function which is included in MATLAB:
Here is an example showing TCP host-target communication:
