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:

The host computer will eventually run a Labview GUI which is why TCP communication was selected, so I don't think the MATLAB API is an option (unless that assumption is incorrect?). That TCP host-target communication example is how I set up the MATLAB GUI-Speedgoat communication for a proof of concept. It was limited though, all it did was write data to the speedgoat. The final product will need to write data (Command Matrix, Parameter Tuning) to the Control Speedgoat and also read data and connection status back from the Control Speedgoat. The Control Speedgoat will then have ethernet connections to other hardware with similar needs. They will all need to recieve data and parameter tuning from the Control Speedgoat, and then respond back with Data and Connection Status. I have attatched a diagram "TCP Network Diagram1" to visually show what I'm trying to accomplish. The other images are the simulink TCP Server and Client blocks I have on the speedgoats. The "TCPServerSS" is running on the Control Speedgoat and the "TCPClientSS" is running on the Client Speedgoat and they are both connected by ethernet. These models compile but like I said I can't run the code t = tcpserver(IP address, port) because I dont have Instrument Control Toolbox. It just seems odd that I have access to the TCPServer simulink block but no way to utilize it, to implement the network in "TCP Network Diagram1" must I have Instrument Control Toolbox? Why? I would also like a way to display communication updates in the GUI like "Data recieved", is there a way to programtically monitor the sockets to see if and when the data has been recieved?
