profibus M12 socket connect to din-9 socket

we bought some ABB soft starter (PST85-600-70)they are supposed to connect a cpu315 via profibus but all softstarter use M12 profibus socket (PDP21-FBP)how can I connect M12 to din-9 socket

Hello UncleHamid;
The simplest way to do this is to get the pinout of both the M12 connection on the softstarter and the DB9 on the master, purchase the M12 and DB9 sockets, and build a converter cable yourself. One advantage: you have no one else to blame if the connections aren't good, and you know how to correct them.
This will work for a single slave, point to point. If you have a number of them, better you go with some manufacturer that specializes in Profibus "patch" cables, M12 connections, T-connectors for multiple M12-based slaves...
Turck comes to mind, they have a great variety of M12 implements and cables (www.turck.com) and a representative in
