CODESYS - the IEC 61131-3 automation software

Hello!
Does anyone know how to realize the communication of Codesys and matlab?
I installed codesysV3.5 and matlabR2017 on the same computer.In codesysV3.5， there was a project to control the robot, and the movement of the robot could be controlled by changing the parameters. I want to use matlab to process the data returned by the sensor on the robot, and calculate the new parameters, and then send them to codesys for real-time control. But I don't know how to implement communication between matlab and codesys. Does anyone know it? Or is my idea feasible?

Hi,
does matlab have an embedded OPCUA client?
This would be a good solution to do this. OPCUA Server is embedded in all CODESYS SL runtimes.

Thank you for your suggestion. I had created a OPC Server on CODESYS and set up a OPC client with matlab which connected the server successfully.

Hi ligz17,

I am trying to implement the same communication: CODESYS OPCUA server with raspberry pi to Matlab OPCUA client.

Unfortunately I did not succeed. Could you post more details of your solution?

I connect with other clients such as python or UAexpert. But not with Matlab or Simulink

I successfully connected with the OPC UA SERVER at the raspberry with the entries below.

MATLAB CODE:
uaObj = opcua('opc.tcp://192.168.100.11:4840/OPCUAServer', 'None', 'None', uint8(0));
connect(uaObj)

Mathworks has suggested to use this undocumented technique until they release a patch/fix to handle better this connection errors.
