Simulink with Modbus TCP in the Realtime Machine

46 views (last 30 days)
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.....

Modbus TCP support for Simulink Real-Time is provided by Speedgoat:

As a workaround, you may use a MATLAB Function block and use modbus object inside it.

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.

Hi, I need Simulink Modbus blocks for code generator,that is, generate code to implement modbus in microcontrollers, using simulink code generation., is this possible?

Thank you very much for answering. I have already managed to port freemodbus 1.6 to all my microcontrollers, PIC18, dsPICs, Cortex M3 / M4.

Hi Fernando,
I want to generate Simulink model for Cortex M3 microcontroller which will provide communication using Modbus protocol. Could you please give me some indication how did you do it? Did you use Modbus Explorer at all?
