Hello forum!

I hope you all can help it will be very much appreciated!

I'm having an issue with uploading NC/PLC data via series upload into my 840DI controller. This problem i think has originated from a dead MCI battery out of the blue which wiped both NC/PLC memory (which has been replaced). My problem is that using the original backups of PLC and NC .ARC files, only NC files upload successfully. Everytime i upload the PLC.ARC file each line of code says error#200#.Sort of similar to this thread (what user Rinaldi says 9th post down, but then their problem seemed to sort itself out). 

I can see all the correct Axial drives are in the HMI etc so the NC upload has gone ok and get no errors when uploading NC.ARC. I check for consistency before upload in HW Config and it says its fine. I also get a host of other errors which i hope disappear after the PLC upload is complete, but i have a feeling they wont.

Error 380040 project error 3 param .

Error 380070 no inbound slot for base address 56,76,78,86,88 (size 2) found

Error 26105 - Drive of Axis not found (applies to all axis)

Error 26106 - Encoder 1 of Axis not found (applies to all axis)

I reckon these NC files are for a slightly different setup as a couple of servodrives have been replaced throughout the history of the machine, and these NC/PLC files pre-date the change. This could mean some tinkering in S7 eventually (i could be wrong?).

What can i do to get past the PLC uploading error to start with? Is their a certain upload procedure? Because i've set the PLC in stop mode prior to starting the upload. I've been reading around the forums that S3/S4 dials need to be in a certain position but my Simodrive U/E module has only got 4 small switches. I also cannot see anywhere else on both my 840DI or drives,profibus etc where these dials or LED numbers are. (maybe a clue in my hardware version?). Servo-drives also read Error E A831 which i think is normal in its current state.

Specs:

Siemens 840DI

Operator Panel: 012 , MCP483

PLC Version: Unsure where to find

PCU50 (i dont think its 50.3) with HMI version unsure

Software available: Step 7, HW-config and other various Siemens/HMI related software

Ability: Advanced Operator

Anymore information required let me know i will do all i can to help!

Thankyou!

Hi,

In Sinumerik 840Di, there is Profibus drives archive, separate from NC archive.

Did you load this archive as well?

Or

Are you sure that your archive consists of Profibus drive archive?

Thanks for the reply!

I’m not sure. Is there a way I can check/verify the contents NC.ARC file for profibus data? When I perform the NC series startup I can recognise some of the files within such as .spf and other subroutines. Otherwise I can’t see anything that shouts profibus unless its written/abbreviated as something else.

Within my backup files I have there .ARC files:

PLC, NC, SPF, MPF, DEF, CONFIG DATA NCU, COMPLETE OPT. There’s also a subfolder containing various .INI files and a couple of MS-DOS aps.

Hi,

You can see the archive with software such as Sinumerik Integrate Create MyConfig Diff. The Profibus drive archive or SDB perhas inside plc archive as well.

You can load here in order we can check whether SDB is inside.

You should do proper sequence of startup. Please follow in the following manual, you can download:

https://support.industry.siemens.com/cs/document/28710259/sinumerik-840di?dti=0&pnid=14595&lc=en-WW

Please check also that Profibus connector from the drives is properly connected to the correct Profibus terminal in MCI board (on PCU). MCI board has MPI and Profibus terminal. If you plug Profibus connector to the wrong terminal, it will not work. Check once more, because it has problem with all of the drives, so it must be common problem.

Hello Cristofoli Int,

Please check HDD of PCU50, it must be having NC & PLC arc files. Try to reload the latest (based on date) & check. 

Morning AutoGen_682194,

I've attached a folder containing all my .ARC files, I haven't got Sinumerik Integrate unfortunately but if you could take a check that would most appreciated!

I've checked I'm in the right MCI slot and it is properly connected and screwed in, double checked cabling from work station to profibus. All visible cable seems ok, no loose ends and no burns.

I've been using that manual previously on performing the NC/PLC series files so that fills me with confidence. I just wanted to check if i needed to set anything on the U/E module of the simodrives or any other hardware setting.

Morning PISCEAN 2010,

HDD seems happy. No major hardware fault there. If you look in the attached folder the NC and PLC files are dated the same and as far as our companies records go this the latest (and only! typical) backup. 

Thankyou all for the replies!

Hi,

I have checked your file, PLC archive has SDB inside. 

Based on earlier information from you that CNC has no communication with all of the drives, the possibilities is following:

1- PLC archive is not correct.

2- MCI board is faulty.

3- Profibus connector on the the MCI or before MCI has problem, example termination switch problem. 

You can check point number 3, if you have Profibus interface in your pc, example CP5711, you can check what is available in the Profibus network. You have to set the interface (CP5711) such as MCI, speed is 12 MB, detail you can find in the manual that I have shown the link above.

If you find the nodes in the Profibus network according the number of drives and MCI, you can eliminate connection problem possibility. Then you have to work with possibilities number 1 and 2. 

Hi All,

I never got back to replying to this thread. I managed to solve this issue by uploading my PLC arc file first then my NC arc file. All then booted up perfectly. This is contrary to the Siemens manual which dictates NC first then PLC second.
