Description
A connection is usually configured in the "Devices and Networks" editor. The graphical representation (Fig. 01) shows a sample configuration of a connection between WinCC Advanced and an IM151-8PN/DP CPU.
In WinCC Professional it is not possible to do a graphical configuration for the IM151-8PN/DP CPU (Fig. 02).
Other CPUs are not affected by this restriction and can be networked and connected as shown in Fig. 01.

Remedy
It is possible to use PROFINET to set up a connection between WinCC Professional and an IM151-8PN/DP CPU, but this has to be done in a conventional manner.
Here, the PROFINET connection is made in the connection editor of WinCC Professional.
 

No.	Procedure
1	Go to the project navigation and choose the "Connections" editor of the WinCC project. Fig. 03
2	In the "Connections" editor you create a new connection by double-clicking "<Add new>". Fig. 04
3	In the inspector window you select the "Parameter" tab and choose "Industrial Ethernet" for the interface. The Ethernet address (MAC address) for the "WinCC RT Prof connection" must match that of the IM151-8PN/DP CPU. Fig. 05
