The following rules apply:One state graph is required per function unit or

24、 task.Usually one state graph is used for every mechanical component of a process. In addition there are further functions, such as for example, the control of the operating modes or the control of operation enables. These are also mapped to a state graph.The state graphs can be structured hierarchi

25、cally. It is thus possible to insert one or more state graphs which coordinate the other state graphs in a graph group.The drilling machine can be divided into the functional units Drill_motor“, “Feed and Vice“. The feed is realized by means of a valve with two limits.The state graphs Motor, Valve_2

26、I and Vice are required to control these functional units. The state graph for coordinating is to be called Drilling.S7-HiGraph for S7-300/400 C79000-G7076-C527-012-6DrillingFeed01131Drill motor11Drill motor onFeedback:2- Drill running0- Drill stationaryValve_2TMotor0101ViceStart button0311 11 31111

The fur

28、ther state graphs required already exist in the supplied example project ZEn03_01_HiGraph_DrilMac.The functional unit on which the “Valve_2I“ state graph is based is a valve unit with two limits. The valve unit consists of the following elements:A solenoid valve for the Up movement“A solenoid valve

29、for the Down movement“ A limit switch for the Top limitA limit switch for the Bottom limit.It is assumed that the solenoid valves only have to be operated for the movement phase and that the valve remains in the respective limit.Determining the statesThe valve can thus assume the following states:S7

32、le of a DrillDetermining the state changeThe Drilling state graph determines when the valve unit changes from one state to the next. For this purpose it sends messages to the Valve_2I.When the valve reaches the limit, a message is returned to the Drilling state graph.Designing the state graphThe str

42、ting the projectPrerequisite for programming with S7-HiGraph is a project in which the data of the S7-HiGraph program is saved.Projects for state graph programming is not different to other projects in STEP 7. Proceed as follows in order to create a new project in the SIMATIC Manager.1. Select the F

43、ile New Project Wizard2. The STEP 7 Wizard which is now started supports you in creating the project. The Wizard prompts you to specify the following data:-Which Cre you using in your project?Specify your CPU. In the supplied example the CPU 314 is used.- Which block do you want to add?Select the OB

44、1.- What do you want to call your project?Enter the name HiGr_Exp.Project structureThe STEP 7 Wizard creates a folder for the station selected by you. This in turn contains a subfolder with the selected CPU. This contains the S7 program with folders for blocks, symbols and sources.When configuring t

45、he structure, an S7 Program directory is automatically created for each CPU you have provided for. This directory serves as the folder for the blocks, the sources and the symbols of the user program.Call the S7 program “Drilling machine“.The following figure shows the structure of the example projec
