It took some digging But I finally was able to open Step7 Lite.zip - unfortunately it is only for Operating Systems UP TO Win XP, not supported & install will halt on WIN7. If you want to learn Step 7 the cheapest way around it would be to buy a used WinXP notebook at the used computer store. Also, since Step7 Lite hasn't been updated since 2009 - no processors made since then are supported, so this would be a learning tool only.

I just downloaded the Step 7 Lite.ZIP package from Siemens and Windows won't open it - it says it's INVALID. I tried CAMunzip & it says its the first disk of a backup and to insert the last disk - then goes into a loop of the error that only can get out of by going to Task Manager & ending the process. Has anyone else had this problem & been able to overcome it?

I downloaded the software and am trying to learn to program it. The problem I am stuck on is programming timer functions in FBD, I cant figure out how to input the time delay to the PT input!

Does RSLinx see the PLC? Can you connect to the PLC? Is it asking for a password? Is it giving a specific error? (like unable to connect without a copy of the program on the PC)
