Hello,

You need only to connect them with cable (both resistor on the connector put in ON). After make hardware configuration on Simatic Manager and download this configuration to CPU.

Hello

What did you mean with profi out terminal? Let's clear the words. This type CPU has 2 inerfaces. Not exacly "in and out terminal". The first one you can find with double click on the CPU. You'll see in Inerface field - Type MPI or Profibus, Address Nr., and if this interface is connected or not. The second interface you can see in X2 field. Wih double click you can see the same properties like previous. So, important is to know, which interface will be use. In your case you decide to use second one. This means that under properties in this interface you must see:

Type: Profibus

Address: 2 or other

Networked: Yes

For other interface (first one) you must set not networked.

Hope, you have already established connection...
