IFix with Siemens S7-300

Hi all,

My project is to connect a Siemens s7-300 to IFix 5.0 (if I switch a button on the s7-300, something, a light for example, change too) but i dont know how to do that.
Do you know where can I fing any tutorials or any help?
Actually, I dont know Simatic s7, and know IFix a little.

Thanks!!

(PS : Sorry for my bad english, french level ^^)

Ok, now I have a connection between SIMATIC Manager and my S7-300.
I loaded the program in, and now i have to make the connection between IFix and the S7-300.
Anyone?
