How can I import data from a table (time, input and output) for be processed in System identification toolbox? Do I have the option to use OPC data?

You will need to bring data into MATLAB workspace as double matrices first. If using System Identification GUI, you can import variables from MATLAB workspace. If using command line, you should create IDDATA object from imported variables to prepare your data for identification.

Thanks Rajiv, I tried using iddata and it works fine. One more questions, do you know if it is possible to link this with OPC data?, I mean real time data.

Thanks in advance
