siemens newbee connection problem

[kolonelvonklink 0]

Hi

My Firm just purchased a Simatic Field PG but nobody here has some decent knowledge about it. It had only been used a few times to make a connection with an external programmer but wasn't present at that time. 

I attended a step 7 course about 10 years ago so now I would like to fresh up my knowledge and use it to debug issues (I'm a maintenance technician).So I took the field PG and some used hardware at home and would like to play with it BUT I can't get no connection with the PLC.

My hardware setup:

Siemens Field PG with Step 7 V5.5 + SP4

available cables: - a siemens cable DB9 male to DB9 male

                              - USB/PPI Multimaster Cable   9SE7  901 - 3DB30-0XA0          USB to DB9     (the 3 LED's light up on connecting the USB but that's it)

PLC:   SITOP Power 5   6EP1333-1SL11

           SIMATIC S7-300  CPU313      313-1AD01-0AB0

           MMI card      MC951/16KB/5V flash    6ES7 951-0KD00-0AA0

          DI32 x DC24V            6ES7-321-1BL00-0AA0

          DO32 x DC24V/0.5A        6ES7-322-1BL00-0AA0

          AI8 x 12bit       6ES7-331-7KF01-0AB0

The current PLC configuration and program doesn't match with this hardware configuration so the SF is on

How do I get started (step by step details please)

 

Thank you

 Happy Newyear

What you want to obtain?

I guess that you want to restart PLC. Is that what you want?

Connect the adapter to MPI port of CPU and to USB at your PG.

Start Simatic manager, Set PG interface according the one that you have.

Open a new project. 

Select PLC \ Upload station to PG

Then you will have the hardware configuration according of reality.(if was not lost from PLC by battery fault).

have a look here:

Once you will be connected to CPU, you may have access to buffer diagnostics also.

Thanks for the reply but:

I connect with the PPI adapter. When I click "upload station to PG", I get a message:

(when PG/PC interface is set as:   PC adapter.Auto.1)     The connection to the module could not be configured.  

(when PG/PC interface is set as:   PC adapter.PPI.1)       With the set interface configuration, communication in Step 7 is not possible.    Then opens a window SELECT NODE ADRESS, in which I click on the View button: With the set interface configuration, communication in Step 7 is not possible so I click OK and then I get Online: communication link to the adapter damaged. (no LED goes on, on the adapter)

 

I tried some other PG/PC interface settings but no succes? Nor with the serial cable.

Oops,

i was not reading carefully your previous post.

You may not use PPI adapter to communicate with S7 300  PLC. 

You must use MPI adapter or Profibus.

Thank you

But, Aaargh, No MPI adapter at hand.

Can you tell me what the PPI adapter and the DB9 cable is used for?

Kolonel

your making this too difficult. Use the db9 male male cable. Go to your pg pc interface and set to 5711 automatic. 

Do you see the node number and baud?

let me know. I can do some screen shots
