[?]: Need help to connect PLC to Matlab
Posted: Thu Jan 28, 2010 4:56 pm
Hy.
I have Siemens PLC S300.
He is connected to computer (which have Matlab and WinCC) with MPI.
I have PID control in PLC. The variable in PLC is in system memory. (For example Set point is type REAL and on location M4).
I have structure tag in WinCC on this location.
How can I read/write from/to this location with Matlab? I don't know from where to start.
