Dear all

i want to connect matlab to s7-1200 for motion control, but i cant do that. i have an matrix which has position parameters to control servo motor but i cant do that. 

So i think i can send this matrix datas to excel, and then i write excel datas to s71200, servo motors.

and it will go where i want and what is matlab's array datas

i see some videos but they only go one cell. i want this;

i have 2 column and very much line. it has x_axis and y_axis information. data must go one-by-one from the line (with 2 column) to s71200. and it take one line, it process it and take next line until the last line

Now questions:

1. How can i do that with simatic opc?

2. Can i do that kepserver than first, easily?

3. do you have any idea for how can i write motions blocks to this on tia portal

thanks for answering :)

Your description is so general, that's hard to advise you. Is it some school project?

Anyway, the least expensive way to communicate a PC and S7 is TCP/IP. AFAIK Matlab can use TCP/IP. So, you can setup TCP/IP server on S7 and connect to it from Matlab. Look for Open User Communication.

As motion control is concerned, here are few links to start with:

at first, thanks to your advice

than, yes it's my thesis.

So, i try to explain more. my project is taking shot with webcam and draw its edges on small gantry. image processing is done with matlab. İ know what pixels has edges in x_axis and y_axis.

this datas (it is matrix and has which pixel has edges) will go to the tia portal and it become a coordinates data. my servos go this coordinates and draw the thing.

and i dont know how can i do that. in attachment i will share some part of matrix
