1Introduction to STEP 71.1What You Will LearnUsing practical exercises, we will show you how easy it is to program in LadderLogic, Statement List, or Function Block Diagram with STEP 7.Detailed instructions in the individual chapters will show you step-by-step themany ways in which you can use STEP 7.Creating a Program with Binary LogicIn Chapters 2 to 7, you will create a program with binary logic. Using theprogrammed logic operations, you will address the inputs and outputs of your CPU(if present).The programming examples in the Getting Started manual are based, among otherthings, on three fundamental binary logic operations.The first binary logic operation, which you will program later on, is the ANDfunction. The AND function can be best illustrated in a circuit diagram using twokeys.Key 1Key 2If both Key 1 and Key 2are pressed, the bulblights up.The second binary logic operation is the OR function. The OR function can also berepresented in a circuit diagram.Key 3Key 4STEP 7 Getting StartedC79000-P7076-C48-01If either key 3 or key 4is pressed, the bulblights up.1-1
Introduction to STEP 7The third binary logic operation is the memory element. The SR function reactswithin a circuit diagram to certain voltage states and passes these on accordingly.Memory ElementKey SSRKey RIf key S is pressed, the bulb lights upand remains lit until key R is pressed.1-2STEP 7 Getting StartedC79000-P7076-C48-01
Introduction to STEP 71.2Combining Hardware and SoftwareUsing the STEP 7 software, you can create your S7 program within a project. TheS7 programmable controller consists of a power supply unit, a CPU, and input andoutput modules (I/O modules).The programmable logic controller (PLC) monitors and controls your machine withthe S7 program. The I/O modules are addressed in the S7 program via theaddresses.Programmingdevice cableProgramming deviceTransferring a programSTEP 7 softwareMachine to becontrolledCPUPower supply moduleSTEP 7 Getting StartedC79000-P7076-C48-01Output moduleInput module1-3
Introduction to STEP 71.3Basic Procedure Using STEP 7Before you create a project, you should know that STEP 7 projects can be createdin different orders.Designing the solution to the automation taskCreating a project (Chapter 2)Option 1Option 2Configuring the hardware(Chapter 6)Creating a program(Chapters 3 to 5)Creating a program(Chapters 3 to 5)Configuring the hardware(Chapter 6)Transferring the program to the CPU and debugging(Chapter 7)If you are creating comprehensive programs with many inputs and outputs, werecommend you configure the hardware first. The advantage of this is that STEP 7displays the possible addresses in the Hardware Configuration Editor.If you choose the second option, you have to determine each address yourself, dependingon your selected components and you cannot call these addresses via STEP 7.In the hardware configuration, not only can you define addresses, but you can also changethe parameters and properties of modules. If you want to operate several CPUs, forexample, you have to match up the MPI addresses of the CPUs.Since we are only using a small number of inputs andoutputs in the Getting Started manual, we will skip thehardware configuration for now and start with theprogramming.1-4STEP 7 Getting StartedC79000-P7076-C48-01
Introduction to STEP 71.4Installing STEP 7Regardless of whether you want to start with programming or configuringhardware, you first have to install STEP 7. If you are using a SIMATICprogramming device, STEP 7 is already installed.When installing the STEP 7 softwareon a programming device or PCwithout a previously installed version ofSTEP 7, note the software andhardware requirements. You can findthese in the Readme.wri on theSTEP 7 CD under Drive :\STEP 7 \Disk1.If you need to install STEP 7 first,insert the STEP 7 CD in the CD-ROMdrive now. The installation programstarts automatically. Follow theinstructions on the screen.If the installation does not start automatically, you can also find theinstallation program on the CD-ROMunder Drive :\STEP 7 \Disk1\setup.exe.Once the installation is complete andyou have restarted the computer, the"SIMATIC Manager" icon will appearon your Windows desktop.If you double-click the "SIMATIC Manager" icon following installation, the STEP 7 Wizardwill be started automatically.You can find additional notes on installation in theReadme.wri file on the STEP 7 CD under Drive :\STEP 7 \Disk1\Readme.wri.STEP 7 Getting StartedC79000-P7076-C48-011-5
