This is recommended for service and maintenance work, for example, to integrate programmed blocks into in an existing project.Brief Description of the Individual StepsThe first time you use STEP 7, install it and transfer the license keys from diskette to the hard disk (see also Installing STEP 7 and Authorization).Before you work with STEP 7, plan your automation solution from dividing the process into individual tasks to creating a configuration diagram (see also Basic Procedure for Planning an Automation Project).Turn the tasks described in the draft of your controller design into a program structure using the blocks available in STEP 7 (see also Blocks in the User Program).You start STEP 7 from the Windows user interface (see also Starting STEP 7).A project is like a folder in which all data are stored in a hierarchical structure and are available to you at any time. It refers you to the relevant chapter thus giving you the opportunity of moving through the manual to find task-related information.As shown in the figure above, you have two alternative procedures:You can configure the hardware first and then program the blocks.You can, however, program the blocks first without configuring the hardware. The following figure shows the tasks that need to be performed for most projects and assigns them to a basic procedure. I have used S7 from time to time over the past two years and I can get by but I am not very.Can be extended as an option by the software products in the SIMATIC Industry Software (see also Extended Uses of the STEP 7 Standard Package)Opportunity of assigning parameters to function modules and communications processorsEvent-driven data transfer using communication function blocksSTEP 7 is the subject of this documentation, STEP 7 Micro is described in the "STEP 7 Micro/DOS" documentation.When you create an automation solution with STEP 7, there are a series of basic tasks. Limitation: Need Power Supply 24V DC via PLC interface ( can be fixed) Limitation: The PC Adapter USB supports transmission rates only up to 1.5 Mbps.STEP 7 for applications on SIMATIC S7-300/S7-400, SIMATIC M7-300/M7-400, and SIMATIC C7 with a wider range of functions:Siemens Guys - Please recommend some Step7 learning resources.
For this, you will need to create the subnets required for your automation networks, set the subnet properties, and set the network connection properties and any communication connections required for the networked stations (see also Procedure for Configuring a Subnet).You can define local or shared symbols, which have more descriptive names, in a symbol table to use instead of absolute addresses in your user program (see also Creating a Symbol Table).Using one of the available programming languages create a program linked to a module or independent of a module and store it as blocks, source files, or charts (see also Basic Procedure for Creating Logic Blocks and Basic Information on Programming in STL Source Files).S7 only: generate and evaluate reference dataYou can make use of these reference data to make debugging and modifying your user program easier (see also Overview of the Available Reference Data).You create block-related messages, for example, with their texts and attributes. Configure networks and communication connectionsThe basis for communication is a pre-configured network. The properties of the modules can also be assigned using parameters (see also Basic Procedure for Configuring Hardware).
DOCPRO, the optional tool for creating and managing plant documentation, allows you to structure the project data, put it into wiring manual form, and print it out in a common format. You can also check whether a user program can run on a particular CPU (see also Hardware Diagnostics and Displaying Module Information).After you have created a project/plant, it makes sense to produce clear documentation of the project data to make further editing of the project and any service activities easier (see also Printing Project Documentation). You determine the causes for errors in user program processing with the help of the diagnostic buffer and the stack contents. (See also Requirements for Downloading.) The CPU already contains the operating system.M7 only: choose a suitable operating system for your automation solution from a number of different operating systems and transfer this on its own or together with the user program to the required data medium of the M7 programmable control system.S7 only: for testing you can either display the values of variables from your user program or a CPU, assign values to the variables, and create a variable table for the variables that you want to display or modify (see also Introduction to Testing with the Variable Table).M7 only: test the user program with a high-level language-debugging tool.You determine the cause of a module fault by displaying online information about a module. Using the transfer program you transfer the operator control and monitoring variables created to the database of the operator interface system WinCC (see also Configuring Variables for Operator Control and Monitoring).Download programs to the programmable controllerS7 only: after all configuration, parameter assignment, and programming tasks are completed, you can download your entire user program or individual blocks from it to the programmable controller (programmable module for your hardware solution).
