Hi,
I would like to kwon how to import or introduce data in simulink, from a vector which I have got in matlab. I mean, I got tha data from a earthquake wave in a vector in matlab, which I want do is to respresent this vector in simulink, in real time in order to send the data with opc to codesys.
Thanks for your time.

The most common case, let's say you have a vector a=0:0.1:1.
Make it a column vector b=a'
Create a time vector to specify the time for each value, for example, t=(0:10)'
Use the "From Workspace" block, specify the data as [t b], which will give you data value 0 at time 0, value 0.1 at time t=1 second, etc.
There are other format too. Take a look at the Help document of the "From Workspace" block.

Thanks mate, I had checked this, but I have been trying again with this box and finally it works. I have lost almost two ohurs due to the simulation stop time.I had just 10 seconds, and the wave didn't represent correctly. Really thanks. But when I made the sim, the wave is directly draw. I mean, for explample, It doesn't print the date in ten seconds. How can I made as the wave were in real time.

Simulation might be faster or slower than real-time depending on the model. If it is faster, you could slow it down close to real-time. See Simulink Real-Time
