MATLAB: Simulink with Modbus TCP in the Realtime Machine

Instrument Control ToolboxMATLABmodbusreal timesimulinkSimulink Real-Time

I saw that there is no Modbus block in Simlunk, and checked the blocks of the Simulink Real Time and could not find it either. How we can create a model that uses modbus to comunicate to the controller if there is no Modbus compatibility in Simulink? The instrument toolbox only can use MATLAB and not Simulink, which I did not know when I bought it…..

Best Answer

Modbut TCP support for Simulink Real-Time requires a dedicated I/O module from Speedgoat, see:

The regular Ethernet ports on the target machine can be used for UDP/IP, TCP/IP, PTP, and EtherCAT Master only.
