1 Introduction1.1 Overview1Introduction1.1OverviewWith the SIMATIC S7-PLCSIM Advanced virtual controllers for the simulation of aS7-1500 or ET 200SP CPU are created and used for the prehensive simulationof functions.Therefore no real controllers are required to test a STEP 7 program.The virtual controllers can also be tested and validated in the context of a systemor machine.The user interface (API)is used to connect the virtual controller to aplant/system or machine simulation (co-simulation).Figure 1-1:OverviewReal worldS7-1500PLCSIM AdvancedHardware ControllerVirtual S7-1500

Mode of OperationSTEP 7(TIA Portal)programA STEP 7 program created in STEP 7 V14(details see chapter 3.2.1)controls aconveyor system.For a prehensive function test,the STEP 7 program isloaded via S7-PLCSIM Advanced into a virtual S7-1500 controller.This controllerinteracts via the API with a co-simulation(system simulation),in order to validatethe STEP 7 program in the context of the system.The material handling system to be controlled consists of two transport belts andtwo robot arms.The following input and output tags are defined so that thecontroller municates with the material handling system:Table 1-1:Input and output tagsTagsDataTypeDescriptionty pesensorStartPosBOOLInputSensor signal:Starting positionsensorBeltStartPosBOOLInputSensor signal:Starting position

monitoring time of 5 s is configured.If thepackage does not reach the target position within this time,an error for a fallendown package is shown ("Package down").You can then restart the system oracknowledge the error when you put the package back on the transport belt 1.Figure 1-3:Overview of the conveyor systemsensorBeltDestsensorEndPosRobot arm1Robot

Advanced.System simulation of the conveyor system (co-simulation).The co-simulation reacts to the control signals (outputs)of the virtual controller andsimulates all required sensor signals (inputs)for the simulation of the sequentialcontrol (details chapter 3.2.2).For the exchange of the VO data the Runtime API writes and reads from thememory area that is synchronized on the cycle control point with the intemnalprocess image of the virtual S7-1500 controller.Table 1-2:Data exchangeVirtual ControllerData

the co-simulation you can simulate or remove errors,for example,drop apackage or place a dropped package back on transport belt 1.NoteThe machines of the conveyor system are simulated in a non-realistic way in theco-simulation.The movements are only simulated by a time constant.S7-PLCSIM AdvancedEntry ID:109739660,V1.0.12/201671 Introduction1.3 Components used1.3Components
