Thread Subject: need to interface PLC with Matlab

Hello Readers
I am interested to know if there is any way to interface a
PLC with Matlab.
I have made some ladder logic programs in a PLC and I have
attached it to the computer through the serial
communication.
Now, when I put the PLC in run mode, I want to see the
values from the PLC in a GUI I made in Matlab. Is this
possible?
Also can I pass values from Matlab to the PLC.
Please guide..
Thanks
Vihang

I'm also dealing with the same issue.

From the researches I've made, I can see that there are 2 ways to communicate matlab and plc. one of them is the opc toolbox in matlab and the otherone is another software by a company you can search it as M2PLC
however, since i am a beginner in matlab I couldn't solve my problem.
They might be helpful .

Thanks Gül
As you have suggested I have tried the OPC toolbox and have successfully interfaced Mitsubishi and Delta PLC to matlab using OPC server.
I will post a sample program to the File Exchange shortly..
