Hi.

I've got siemens automation tool 3.1 installed, free version.
The program got installed so that i could down- and upload programs to relevant CPU's.

But each time i try i can't get permission, also when I try to change IP address it is not possible.

Im trying to download new program to a S7-300 cpu and changing IP adress on the CPU, TP1200 panel and similar slave panel.
