I am not fully familiar with the Siemens product line so I thought I would post a small question session here concerning the Siemens Product line.

In a machine that is currently in house here they have a Siemens PLC. It has a hard drive in it. Or so I have been told, I have not personally seen it. Also I have been told that this unit is programmed in Delphi.

So with that being said did Siemens make a PLC with a hard drive that was programmed in Delphi?

If so what did they call it? Step 5, Step 7 or what?

Is there someone on this site here who is versed in Delphi and is prefered to be in the state of PA?

I ask this because I am reported to have a dump of the program and would like someone who is knowlegable in the area to guide me thru it. If they can.

Thanks and have a great day.
 
Hello,

>So with that being said did Siemens make a PLC with a hard drive that was programmed in Delphi?

I do not know if that is the case but, I do know a bit about Delphi, if you are referring to the programming language.

>...a dump of the program...

Do you mean you have the source code of the program?

I think it´s Siemens M7 you are facing, It could be programed with C or C++. But as I recall they dont manufacture them any more.

Post the dump, I´m sure that we (members) can guide you thru it.

Mark, good day, to answer your questions, Yes I am talking about the programming language Delphi and there are a lot of terms that get used, some same dump some say source code, but it is the source code, I do not have the source code on PC I only have it in printed format, it was all I could get at this time. But I could scan off some pages and email them to you and then you could definately tell me if its Delphi or not. That is if your interested.

Hello mrtweaver;
Scan the first page of code, at least and post it here (as a jpg) so more of uds can have a look, and give opinions.
As edda pointed out, Siemens had a M7 processor for the S7-300 and S7-400 PLCs, processors with a hard-disk that ran C/C++ code.

M7/S7 installation and operation manual:
http://support.automation.siemens.com/WW/view/en/1136201
M7 system software design:
http://support.automation.siemens.com/WW/view/en/1136533
M7 ProC/C++ Writing C programs:
http://support.automation.siemens.com/WW/view/en/1137408

However, all M7 programming used C/C++ (with a Borland C compiler package if I remember well). I don't see how a Delphi program could run on it.

There is also a programming language used in S7-300/400 PLCs known as SCL, that is loosely based on PASCAL. Maybe something to look at when we see your code.

Here are the first 3 pages of what I have. Total content is probably like 50 pages or so. I have asked around here at work and some people say that it looks like the old Pascal or the middle ground between pascal and C. But are unsure. I of course was told that it was Delphi so I dont know but anyone that can help I would greatly appreciate it.
 
Well I´m no Delphi expert but It doesn’t look like any delphicode I´ve ever seen...
In fact it doesn’t even look like a high-level programming language.

If you have the machine in the house why keep us in the dark. What is the serial numer etc on the equipment?

Is it really a Siemens PLC? Or other Siemens Equipment?
 
Hello Simon;
I hope this applies in this context:
FUP is the German translation of FBD (function block diagram), a programming language that represents networks as logic gates (AND, OR, NOR....).
FW stands for firmware, in English and German.
Hope this helps,
Daniel Chartier
