313c

Hello Dreni;

This CPU does not have an integrated Profibus-DP port; you must use a CP 342-5 to enable connection to a DP network, as master or slave:

Look at this collection of FAQs for sample projects:

What master/slave communication options are available on PROFIBUS DP?

Study the example with a S7-300/CP 342-5 (as master) to a CP 315-2DP (as slave) to serve as a basis for your project; select the proper slave CPU for your configuration..

Hope this helps,

Daniel Chartier
