Siemens S7 PLC SD memory card

malcoa · Jan 7, 2012

Hi guys, i've been trying to copy the program on an S7 EPROM mmc and backing it up to another, I'm using a siemens field pc to read the program, i can Copy but not paste, I can't find any way to duplicate what's on it, for some reason the plc will not let me communicate through the mpi. Any ideas?

Is the port being disabled by the program i.e. program sets the port to freeport mode?

Perhaps you need to stop the PLC (run/stop switch) in order to access it?

If you're using the FieldPG then have you tried using the card port on the left hand side?

I've not done this for a while and I'm not back in til Monday.

A good site with good info: PLCS.net - Interactive Q & A - Search Results

Good luck.

It promptly goes into bus fault upon connection to the mpi. a dialogue box opens and suggests that the transferr rate is changed or that the address is too high (set to 1), i have been through all the transfer ranges and altered the address but no change. to be honest i only need a copy of the program which is on the sd card which i cant save as a new project or anything else-i cant save it to the pc full stop even though i can read it.

Nice Link Silva, thanks mate.

I've used the card slot on the side silva, i can view it from there fine, i just dont seem to be able to anything with it.
Thanks for the links i'll have a look, i couldnt find anything on the siemens site.

i can Copy but not paste,

Have you tried Ctrl + V command to paste ?

As another poster suggested, you may have to set the Run/Stop switch to Stop first.

@malcoa Have you tried starting a new project then Copying from Card?

One of the manuals here will help. Siemens SIMATIC Step 7 Programmer's Handbook

p161 of Programming with STEP 7 Manual

tried that also silva, i've even tried copying and pasting it into the directory for the memory cards lol, it wouldnt paste as i thought, reading the info from your link it looks as though i may only be able to extract through the cpu.
thanks for the help

I'm back in work in the morning so I'll have a tinker and post any finding!

I did not think "copy & paste" worked like this in the S7 software.

Crashed and burned, pulled my hair out and ran in circles for a bit!

Our FieldPG's (problematic) have been replaced with Panasonic Toughbooks so licenses transferred. I couldn't get comms with th FPG's.

With a PTB I could archive to the MMC but could not retrieve anything. I tried numerous things to no avail. Further action required... if I get chance. Also, my 64kb and 512kb cards were too small to save anything to. I'm sure I had more luck with the onboard MMC slot of the FPG in the past.

Siemens always provide a very steep learning curve... character-building stuff!

Ongoing!!! :banghead:

Had half hour with it this morning. FieldPG with onboard MMC slot. Also tried with MMC in 313 CPU.

Took screen shots but haven't had time to complete writing. Read card in onboard MMC slot. Created Memory Card File. Copied from Memory Card File and pasted in MMC...

Thus so far... View attachment 9829

Sorry for the late response, ive been on nights but this is fantastic, well done! i've scoured the internet for this answer, it'll be sunday before i can get the machine back to try this, i'm made up thanks very much for the time you have put in.

silva.foxx · Jan 11, 2012

You're welcome.

I'm on nights tonight so I'll have (less managers) more time to tinker.

I had some MPI issue with the FPG assuming license issue prevented comms. but thinking back STOP led was flashing on CPU, when MRES triggered... led went solid and comms. continued. Seems wrong so I'll recheck that.

I'll try and complete a rewrite of the PDF.
