Converting from S5 to S7

I have been asked to look into replacing four existing S5 PLC's
with four new S7-300 PLC's.
I have some files which I am told are the program.
The program was originally written by a company in Germany that
no longer exists. I assume it is written in S5 Statement List
with some comments but all in German.
I have Step7 V5.3 but nothing for programming S5

I have several questions.
1. How can I obtain S5 programming tools?
2. How can I look at the S5 code?
3. Can I somehow import this code into Step7 V5.3?
4. Can I convert this code automatically into S7 code?

John,

I'll try to answer all of your questions.
1. How can I obtain S5 programming tools?
2. How can I look at the S5 code?
A good tool could be S5 for Windows. Because you don't need it over a longer period of time, you'll probably find the demo sufficient. This software uses a different format to store the S5 programs, but you can import and import Siemens style Step5 files without any problem.
3. Can I somehow import this code into Step7 V5.3?
4. Can I convert this code automatically into S7 code?
Well yes. There is a tool in the STEP7 package called 'Converting S5 Files'. I have found that this tool can translate about 80% of the programs I have used automatically. If not everything is translated, the tools gives guidance on how to fix it manually. Only a small number of instructions has no translation or no tips on how to translate to S7.

I hope this info will get you on your way. Good luck with the translation.

Kind regards,
 
John,

In answer to one your questions..

2. Ask some kindly sole who has Step5 to print out the program to a text file for you, or even to a PDF file for you.

I did edit this message as I see Jean Pierre answered while I was busy typing, so rather than duplicate the answer he has given, I just gave you one answer

Thanks jvdcande and PLucas for your posts,
I will try to find somebody with the S5 programming tools.

jvdcande - I tried to download "S5 for Windows" but was unable
to find exactly that name. I downloaded "S5 S7DEMO ENG.exe"
but got a message saying it was not executable (PC is XP PRO)
Did I pick the wrong download?

That's the correct program. I just tried it myself on my laptop with XP Pro and it works fine. The file you download is a self-extracting zip file. You can extract it with Winzip if you prefer.

Converting S5 to S7 is part of the Simatic software.

Select Start->Simatic->Step7->Converting S5 Files

Hello guys? Sorry I didn't reply to the questions directed at me, but I have been away for a seminar all day. My fingers are itching like hell because I didn't touch a keyboard all day long.

Eric and Paul: many, many thanks for taking over.

Kind regards,
 
S5 to S7 conversion

I now have a pdf of the S5 program (via Siemens contact in Singapore).
I have tried the Step7 S5 to S7 conversion which comes up with
a lot of warnings but only about 6 errors.
Now I don't know what changes to make to fix the errors but
can try using trial and error.
However, more importantly I haven't found in S5 to S7 conversion
(or elsewhere) some means to make the changes either to the
original S5 program or to the S7 conversion.
I have tried S5 S7 for windows but it seems to find more problems
than the Siemens S5 to S7 conversion.

Can somebody guide me in the right direction?

John, depending on where you are in Tasmania there is a Siemens Solution Provider with offices in Hobart & Launceston who might be able to save you a heck of a lot of heartache

Regards, Dave
