Process When you take a closer look at a process you want to automate, you will find that its ma e up o a mu u e o sma er sec ons an su -processes, w c are ainterlinked and dependent on one another.

The first task is therefore to break down the automation process as a whole intoseparate sub-tasks.

Hardware and Each sub-task defines certain hardware and software requirements which mustSoftware be fulfilled by the automation system:

Hardware:

- um er an ype o npu s an ou pu s- Number and type of modules- Number of racks- Capacity and type of CPU- HMI systems- Networking systems

Software:- Program structure- Data management for the automation process- Configuration data- Communication data- Program and project documentation.

Project In SIMATIC S7 all the hardware and software requirements of an automationprocess are managed within a project.A project includes the necessary hardware (+ configuration), network(+ configuration), all the programs and the entire data management for anautomation solution.

Introduction The SIMATIC Manager is a graphic user-interface for online/offline editing of S7o ec s pro ec s, user program es, oc s, ar ware s a ons an oo s .With the SIMATIC Manager you can:

manage projects and libraries, activate STEP 7 tools, access the PLC online, edit memory cards.

Starting the There is an icon "SIMATIC Manager" on the Windows 95 desktop and aSIMATIC Manager "SIMATIC Manager" program item under SIMATIC in the Start menu.

-clicking on the icon or via the Start menu

START -> SIMATIC ->

User-interface After installation, the main tool is available as an icon on the Windows 95 desktop.The SIMATIC Manager manages the S7 objects such as projects and user

Project Structure Data is stored in a project in the form of objects. The objects in a project are

arranged in a tree structure (project hierarchy). The tree structure displayed in the

project window is similar to that in the Windows 95 Explorer. Only the icons for the

objects are different.

Project Hierarchy 1st. Level: The first level contains the project icon. Each project represents a

database where all the data relevant to the project is stored.

2nd. Level: Stations (e.g. S7-300 Station) are where information about

the hardware configuration and parameter assignment data

of modules is stored.

Stations are the starting point for configuring the hardware.

S7 Program folders are the starting point for writing

programs. All the software for a parameter-assignable

module from the S7 range is stored in an S7 Program

folder. This contains further folders for the blocks andsource files of the program.

Subnets MPI Profibus Industrial Ethernet are art of an

overall network.

3rd. and subsequent levels: Depends on the object type of the next-higher level.

General Before you download the user program to the S7 PLC, you should reset the CPU memory o ma e sure ere are no o oc s e n e .

The following takes place during a memory reset:

All user data are erased(with the exception of the MPI parameter assignment).

Hardware test and initialization

If an EPROM memory card is inserted, the CPU copies the contents of theEPROM back into the internal RAM after memory reset.

If no memory card is inserted, the set MPI address is retained. If, however, amemory card is inserted, the MPI address entered on the card is loaded.

The contents of the diagnostic buffer (can be viewed on the PG) areretained.

Note The CPU must be in the STOP mode for a memory reset:

Mode selector in STOP or Mode selector in RUN-P and mode changed to STOP by selecting the

menu options PLC -> Operating Mode -> Stop.

Exercise Perform a memory reset of the CPU (with the keyswitch or from the PG).You can check if the memory reset was performed successfully by checking thecontents of the block folder in the Online view. Only system blocks (SDB, SFC andSFB) should now exist.
