Siemens Website Quick Links This is a listing of tutorials and manuals found on the Siemens automation website that will get you started on the SIMATIC Step 7 software for S7-300 and S7-400 systems. From a new users perspective I’ve only heard disparaging comments about finding the right information on the Siemens’ website. I have to agree. Its information overload at it’s best.

There’s a lot of different stuff there thrown together and found in different spots with very long URL addresses to add to the confusion. Have no fear. We’re here to help.

So we’ll look at the essentials for your journey. • The software if you haven’t got it yet • Getting a sense for the product line • Where to start with the manuals • Online training material • Downloadable Flash tutorials Of course the best type of is the hands on type but if that’s not an option then you’ll need to start digging in. Who’s got the Software? Harris unity radio programming software. If you are just learning and can’t easily get the software then there are two options. • which will give you a free 30-day trial period.

While it’s not the complete picture it does ease you very well into the learning curve of the Step 7 software. • - Here’s the fuller manual for the programming interface which is also the same as the online help accessed by pressed the F1 key. • - Everything to do with the Hardware Configurator.

•,, and - These manuals contain both the user’s guide and the reference description of the programming language or representation type. You only require one language type for programming an S7-300/S7-400, but you can mix the languages within a project, if required. If you’re more comfortable with Ladder Logic or Function Diagram then start there but sooner or later you’ll have to become familiar with Statement List. • - The S7 CPUs have integrated system functions and organization blocks included with their operating system, which you can use when programming. This manual provides you with an overview of the system functions, organization blocks, and loadable standard functions available in S7, and detailed interface descriptions for their use in your programs.
