Task
PROFINET's popularity in the automation industry is increasing continuously. So there is often the task to realize a coupling to PROFIBUS DP networks from existing plants or plants,which could not convert to PROFINET yet.

In pure DP networks, this task was solved up to now by DP/DP coupler. But current, there is no suitable product available- means a PN/DP coupler, where the PN part presents oneself as device and the PB part as slave.

Solution
For this task the S7-1200 offers a cost-effective and capable alternative. In conjunction with the PROFIBUS DP communication module CM 1242-5 and the PROFINET I-device function the S7-1200 becomes a gateway between PROFIBUS and the PROFINET system part.

As I-Slave in the PROFIBUS network
As I-Device in the PROFINET IO network.
The S7-1200 transfers cyclic I/O data between the both networks. The data transer is completely transparent.
In this application an S7-300 represents the PROFIBUS system part, an S7-1500 represents the PROFINET system part.

How do you configure a PROFIBUS/PROFINET communication between two projects in TIA Portal?
https://support.industry.siemens.com/cs/document/109792607/
For the communication between two projects with the S7-1200/S7-1500 you confecționate a GSDML file for one CPU, which you then install in TIA Portal. You configure the device from this GSDML file in the second project as a distributed IO device.

The following procedure describes the project engineering of the communication between a project with a S7-1200 CPU and a project with a S7-1500 CPU. The S7-1200 CPU is additionally connected to a S7-300 CPU via PROFIBUS. A GSDML file is created for the S7-1200, installed in TIA Portal and the device from the GSDML file is integrated as a distributed IO device in the network of the S7-1500 of the second project.

Create a new project for the S7-1200 in TIA Portal and insert the two CPU modules "CPU 1215C DC/DC/DC" and "CPU 315-2 DP" into the project.
Note
I-Device on the S7-1200 is supported with firmware V4.0 and higher.
Insert a communication module "CM 1242-5" for the S7-1200 and configure the PROFIBUS connection to the S7-300. The assignment of the module "CM 1242-5" to the DP master is automatically done by the networking.

To configure the I-Slave PFOFIBUS communication, open the properties for the module "CM 1242-5" and add the two transfer areas as shown in the following screen under "DP interface > Operating mode".

Open the properties of the S7-1200 CPU and activate under "PROFINET interface [X1] > Operating mode" the function "IO device".
Configure the two transfer areas for the I-device communication as shown in the following figure.
Save and compile your project. After error-free compilation, you can export the GSD file.
Then click "Export" under "Export generic station description file (GSD)" and export the GSDML file to a path on your hard disk.

Install the GSDML file in TIA Portal. How to install GSD files is described in Entry ID: 109738401.
Create a second project in TIA Portal and add the CPU module "CPU 1511-1 PN".
The device from the imported GSDML file is located in the hardware catalog of the Network view under
"Other field devices > PROFINET IO > PLCs & CPs > SIEMENS AG > CPU 1215C DC/DC/DC".
In the Network view, drag and drop the device into the network.
Configure the PROFINET connection between the S7-1500 CPU and the "DP standard slave" ("GSD IO device").

Configure the transfer areas in the Properties for the CPU module "CPU 1511-1 PN" under "PROFINET interface [X1] > Operating mode".
Note
You must configure the IO data exactly inverted in both projects.
