Hello,

http://www.profibus.com/

Hello Bill;

As you can see from the replies you already have received, your question is woefully inadequate.

Do you need theoretical information on Profibus? Then open Profibus.com and their Downloads and Technology links, where you can find many instructive documents on installation and maintenance of Profibus-DP and Profibus-PA networks, along with descriptions of the different actors in the bus. Siemens Support also has many documents on Profibus networks; simply use the Site Explorer search box at the right of this page to search for manuals, system descriptions application examples, FAQs....

Do you have a specific project in mind, with selected material on which you need some support? Give us a clear description of your requirements, and we will gladly help you out if we can.

Hope this helps,

Daniel Chartier

Hello everyone

Please tell me the material for the data exchange with Profibus DP (master and slave).

Desirable with examples

Thank you

 Hello,

some infos:

What master/slave communication options are ... - Siemens Support

How can you communicate data between the S7-200 and the S7-300 via PROFIBUS DP?

how to configure s7-300 and s7.1200 ... - Siemens Support

but if you explain better what you want to do........

Regards

Bill

Hello Bil;

I am sorry, you are going to have to show more precision whn you come to the forum and ask for help.

 For example:

- The CPU 314  you mention cannot be a Profibus-DP master (without a CP 342-5), unless you mean a CPU 314C-2DP; provide the complete part number please.

- There is no IM 151-C in Siemens equipment, unless you mean an ET 200S head module (IM 151-1,  IM 151-7...); what is the complete part number (again) of the Profibus slave you want to connect?

-Are you using Simatic Manager (what version, 5.x) or TIA Portal (what class of Step 7. Basic, Advanced..., and what version, v13, v13.1...).

Note that Stefano (STE39) has already provided interesting links that can provide guidance in setting up a S7-300 CP as Profibus master and another CPU as a slave. For my part I can propose a section of the Siemens programming tutorials (in Word format), one that deals with the configuration and data exchanges of a CPU 314C-2DP master and a IM 151-1 slave:

Modul_D16 - Siemens

Hope this helps,
