I know two alternatives:

1 – Use M7
but is not more available
see Update http://support.automation.siemens.com/WW/view/en/14044569

2 – Use a PC + C program + WinAC - only as input / output interface

For programming an S7 controller you can't use C or C++ directly.

You can use the programming language S7-SCL, which is an high-level programming language for S7 controllers (similar to PASCAL). S7-SCL can be used for all nearly S7 controllers.

The other way (mentioned above) is to use WinAC (a software S7 controller, which is running on a PC) together with WinAC ODK. Have a look at the A&D Mall (https://mall.automation.siemens.com/) for a detailled description of WinAC ODK.

Here is an example for using the WinAC ODK:

Is easier to program in ladder.
I learned in one week. Know this OB 1 is your function main, Ob100 is the restart function, OB 35 is your cyclic function. OB82 is your hardware interrupt;
Procedures is your FC;
Functions is your FB associated to your DB (declaration of variables);
Then rock on.

Together with the FM configuration package there will be installed some examples

You can start with SIMATIC FM 350-1 First Steps in Commissioning

Follow instruction from this manual you'll need from Configuration Package for FM 350-1 and FM 450-1 Counter Modules

After installing and connecting the sensor, you need only to create logic in Step7
Perhaps this manual also is usefull SIMATIC FM 350-1 Function Module

The following brochure from Siemens A&D explains the different families of ET 200 compact slaves available
https://www.automation.siemens.com/salesmaterial-as/brochure/en/brochure_simatic-et200_en.pdf
Hope this helps

ET200L
ET 200L is a small, compact I/O device with degree of protection IP20.

The ET 200L is mainly used for applications in the low-end performance range which require few inputs/outputs as well as for applications where space is limited.

The ET 200L is a passive node (slave) on PROFIBUS DP with transmission rates up to 1.5 Mbit/s.


ET 200S
The SIMATIC ET 200S is a distributed I/O system to IP 20 degree of protection. It comprises:
Interface module with PROFIBUS (alternatively with integral CPU) or PROFInet interface
Input/output modules
Technology modules
Frequency converters and motor starters for three-phase loads

Its extensive module spectrum and system-wide handling of configuring, installing and programming tasks make the ET 200S well-suited as a universal I/O system.

The discretely modular design ensures fast and optimum adaptation to system requirements:
No need to keep spares
No superfluous channels

Even when requirements change frequently, replacement or combining of different I/O modules can noticeably reduce setting-up times.

With a data signaling rate of up to 12 Mbit/s on the PROFIBUS DP and extremely powerful internal data transport capabilities, the ET 200S is also eminently suitable for extremely time-critical applications.

Two different versions are available for integrating safety technology with ET 200S.
With conventional wiring, SIGUARD components achieve Safety Category 4 according to EN 954-1 with motor starter applications
PROFIsafe components replace the wiring-based safety logic with a freely-programmable controller. This has the following advantages for the customer:
programming in the familiar STEP 7 programming environment in the LAD and FBD languages;
no separate tool is required for programming or configuration
the safety program executes in the same controller as the standard program;
a separate controller is not required
safety-related data can be transferred over the same fieldbus cable as standard data;
no additional wiring of the safety-related inputs and outputs is necessary
safety-related inputs and outputs can be combined with standard inputs and outputs within a DP station;
no additional safety-related DP nodes (stations) are necessary

The design of the ET 200S allows it to be used in areas subject to increased mechanical stress.

The system characteristics meet high plant availability requirements

you must be careful during the upgrade operation , because many problems may meet u with Step 7 While working with step 7 on Windows 7,

and I Think That This thread will be useful for you
https://www.automation.siemens.com/WW/forum/guests/PostShow.aspx?PageIndex=1&PostID=167659&Language=en#top

How said ------ be careful. Is possible after upgrade to Windows 7, when you try to start Step7 to receive message
Your user rights do not include the use of Step7
And how ------ said - "This Windows may contain bugs

My opinion is also the same. Don't trust so much to Microsoft. Each new release from them "is perfect, faster, without bugs...", and suddenly just after official release of the product, they prepare Hotfix 1,2... or even SPs...So keep current position a little bit more and let's hope that really this new Windows would be better.

I have Windows 7 (Retail) Ultimate x64.

I have installed Step 7 v5.4 into the Windows Virtual PC. Using the virtual machine, run the automation license manager and transfer the licence onto the virtual machine.

Then I can run Step 7 on the Windows 7 desktop using XP Mode.

I have only installed today and so cannot say about long term usability or relability, but at least it installed. I could not get an install to succeed natively on Win7

No tests of communications (ie ethernet or USB) have been done yet. I have no hopes of getting USB to work!

This is for testing purposes and I will NOT be taking it to site

usually, HattedOne, the communications works fine via ethernet and/or usb.

i didn't tried with win7, but when i was using vista, i installed winxp on vmware to run wincc 6.2. i could communicate using ie general nomally.

i also have a virtual machine running win98 and use it to communicate with S5 plcs via serial cable .

however, if your only communication option is a CP5512 or any other PCMCia card, forget it

It is not possible to connect any other modul to the FM352-5

The FM352-5 can run in stand-alone mode without a CPU, but only running its self-contained program. A CPU is required to pass data from the system (or any other card in the system) to the FM352-5 so it can respond to an input value or limit

as i know the firmware will be released this month

ونحن بصدد الإعداد للخوض في إطار هذا الموضوع عند استئناف موضوعات الدورة المتقدمة إن شاء الله

Perhaps you could start with S7-300 CPU 31xC Technological Functions . Take a look there and then we could continue

http://support.automation.siemens.com/WW/view/en/12429336

Yes you can. My advice is to use Profinet because of high speed. 8 HMI will require some bandwidth, so its better to have a lot of it

yes you can used FM 353 Positioning Module Which will provide the

Positioning module for stepper motors in machines with high clock pulse rates

Can be used for point-to-point positioning tasks and for complex traversing patterns

You can set a block protection for blocks by adding the attribute KNOW_HOW_PROTECT when programming the block.

Activating block protection has the following effects:
If you later open a compiled block with the incremental STL editor, the statement part of the block cannot be opened anymore.
The declaration part of the block will only show the variables of declaration types VAR_IN, VAR_OUT and VAR_IN_OUT. The variables of the declaration blocks VAR and VAR_TEMP remain hidden.

When activating the block protection, the following applies:
The keyword is KNOW_HOW_PROTECT. It is entered before all other block attributes.
OBs, FBs, FCs and DBs can be protected this way.

The following SCL function is used to clearify inserting the line KNOW_HOW_PROTECT:

During the compilation, a function (in this example FC2) is created in the block folder. A lock on the block symbol in the SIMATIC Manager signifies the protected function.

In the last step, the SCL source is deleted. The content of the function cannot be altered or displayed anymore.

Attention:
After the deletion of the CFC chart and the SCL source, the block cannot be changed anymore and the Know How protection cannot be removed anymore.
