Upgrade program. From step7 micro/win to simatic manager

Dear experts,

I have SPM machine with 2 motion control using S7-200 cn. Schieder drive and motors,

Can I upgrade it simatic manager as it is working machine.

I need to change only PLC or can it possible migration directly from S7-200 to simatic manager?.

Thank in advance

No.

Hello Expert's

Thanks for quick response DP

With TIA portal v13,v14  is it possible?

Please advise me with any solution.

Simatic Manager is not TIA Portal. Which PLC do you have in mind to use? Or are you out on a fishing expedition? What do you consider an "upgrade"?

The S7-200 was not developed by Siemens. Converting S7-200 code to S7-1200 was however possible with a converter program available for Step7 V11 (TIA). A few problems:

• The converter program is difficult to get. Need to ask Siemens Office for it.
• Converter program is only for Step7 V11 (and V10.5).
• Only basic code converting. Motion control cannot be converted.
• Converting is not clean code. Much work is required to clean it up.
• PPI communication is not compatible with the other S7 PLCs. The reuse of the HMI / SCADA is going to be a problem.
  

The other option for people from India and China is to use the S7-200 SMART product range.

There is no shortcut for you. Choose a controller family that can deliver the control cleanly. Consider to use a dual controller solution, to phase in the new controller to take over the control from the S7-200.

As I do not know the depth of your problem, I am unable to suggest more detail.

@dchartier - Would you be so kind as to weigh in your opinion on how to approaching this case.

Hello Ramesh;

There was a converter tool available for migration from S7-200 (Microwin v4) to S7-1200. But originally on;y for Step 7 Basic v10.5, later extended to Step 7 v11. It was removed from later versions of Step 7 (TIA Portal).

Have a look at the following discussion for more information, and a possible download path for the converter program.:

Hello #dP;

To tell the truth, I have had bad experiences with pre-made converters, even from Siemens. The TI545 to S7-300 converter was a mess and generated a single program file (OB1) if you did not take the time to split the TI rungs into separate functions for the S7 program; which did not make sense to the program until you re-programmed everything; the S5 to S7 converter requires the elimination of most communication and control functions in the S5 program before conversion, then using the S7 equivalent instructions and configurations in the new system. 

Basically, I tend to be a bit conservative when I face a conversion from one system to another these days (I have had to manage migrations  between Controllogix and GE CPUs, bewteen S7 and Controllogix): to do this efficiently you really need a programmer who is fluent in both systems, and who also has studied the original project and all its details. I then treat the conversion as a programming of the plant functionalities in the new programming environment. It saves time and frustration.

Even Siemens tends to treat the conversion of a S7-200 to a S7-1200 CPU as a "transition" rather than a conversion.  This implies a compete reprogramming in TIA Portal, See this article on the subject:

https://w3.siemens.co.uk/automation/uk/en/automation-systems/industrial-automation/migration/pages/s7-200-to-s7-1200-migration.aspx

https://w3.siemens.co.uk/automation/uk/en/automation-systems/industrial-automation/Migration/Documents/Transition%20Manual.pdf

Notice that it the webpage and in the document there is no mention of a conversion software between the 2 platforms.

So I leave traditional converters to the beginners in my group, so they can try to figure out the error messages they get when they use them for the first time. It can be an excellent learning tool.

Hope this helps,

Daniel Chartier

@Ramesh: FYI the "TI" spoken about is short for Texas Instruments. The S7-200 is also a Texas Instruments creation.

I have executed several S7-200 to S7-1200 conversions where motion control was involved. The S7-200 programs were designs I made previously to replace old expensive S7-300 designs.

The "translation" program works if you know the what the convert program can do, know the PLCs and understand the controlled process. It will not be possible for me to make a step-by-step recipe for someone to follow.

@dchartier: Thank you for engaging me in this conversation. Your expertise is legendary. Your footprints of valued contributions are not only here but also scattered over many control systems sites.

This quoted part goes to the heart of the matter.

Conversion projects takes more time than one expects, but it is a very good teacher for those who can afford to be patient.

Would you agree with these steps?
(as inspired by your previous answer)
1. Choose a design platform (new format).
2. Breaking the program into functional groups.
3. Study and document a functional group as per original format.
4. Start coding/converting a functional group in new format.
5. Test functional group, if possible.
6. Repeat 2 to 5 for all functional groups.
7. Integrate all pieces to one.

Additions? Notes? Comments?

Hello #dP;

Thanks for the comments, although I do feel they are largely undeserved.

As far as your list is concerned, I find it quite complete. I would only add simulation to the testing step of every new function created in TIA Portal (if this is the end software) during development, before trying to assemble the end-product.

Also, I think you should take into account the amount of time lost in cursing and crying when the results don't meet expectations, and the time spent at the bar trying to regroup after long and arduous weeks of work.

Hello Expert's,

I understood your both valuable experiences.

I forgot to share one thing.

Which we have S7-300 312C CPU already

And we not purchase any other hardware.

So be clean it now and we above mentioned software in this post.

Secondly I have also done migration from S5 to S7 but that time I also face similar problem many code are shown errors while complied it.

Need to clean it one by one and it's taken too much time.

So any way I will start as new program on simatic manager for my machine.

Thanks for both of you share your experience, Which support to take my decision starting new fresh programming
