Downloading project from the PLC

Hi all,

Greetings of the day

How can I download a project which is already running in a PLC?

If I dint added an SD card and archived the project into it is it possible to recover my project from a running PLC?

Any solutions for this

Hi

make me understand: the author of the SW on the PLC is you and therefore you own the source?
In this case, what do you need to do a down load from the PLC the program?

If instead you do not own the source and therefore you are not the author of the SW or this is not delivered to you by the person who designed it, you cannot download it from the PLC, because what is inside the PLC is a compiled one.

You can make a copy of it, not editable, with an SD card.

You can use the instructions that you can find in my App for this operation

But you can't decompile it and edit it

I am not the author of the PLC program

But I should edit the program what are my options sir?

None,
the compiled form of the program that is inside the PLC serves to safeguard the copyright of those who developed the SW on the CPU. These are the rules, and not only of ABB's PLCs ....

You have to ask who developed the source, but this may not be foreseen in the costs of the machine where it was mounted or it may have costs because the ownership of who developed the program, in many countries of the world, remains of who has it done. Otherwise known as copyright ....

Sir let me tell you one my assumption

While I have the program file I can take that program into an automation builder and I can edit and then I can send it to the PLC right?

Or I should make the whole program again!

As I know it isn't a big project I/O s are less than 100. so I think if I didn't get the source file I should make a new program for the CPU

Correct me if I'm wrong anywhere

Thanks for your time

if you have the source file, you can edit it on Automation Builder, compile and transfer it to the PLC.
You don't have to redo the whole program, in this case!

Very often, if the size of the program is not extensive - as I understand from what you write - it might be more convenient to rewrite everything from scratch, rather than making changes on what other people have thought and therefore making a double effort: first understand what they wanted to do, and then fix it with new specifications.

Sir the program was done by somebody and now it is in control of our company

just need to change one of the outputs. That's all needed to do for the upgrade

Just one more thing

I can export the clone of the program right?

With the help of the clone can I make a new program just like it?

No
unfortunately, whether it is a substantial part of the program or a single exit, you cannot make changes unless you have the source ...

Dura lex, sed lex!

As for the clone you can do, you have to understand that it is a closed box: it works, but you cannot look into it and open it to change something. Basically, having a copy of how the PLC works is your right, and in fact you can do it with an SD and following my instructions. But you can't change it.
This topic, if you search the forum, has been much debated, even in the past.
I cannot exclude that in ABB someone may have the tools to de-compile a program and make it editable, but these are not in the possession of users, nor even of ABB dealers.
