The next sections deal with the configuration of PROFIsafe communication via PROFIBUS between the integrated drive unit SINAMICS S120 of a SIMOTION D or CX32 and a higher- level SIMATIC F-CPU.
Topology (network view of the project)
The basic topology of the components involved in PROFIsafe communication via PROFIBUS (SIMATIC F-CPU and D4x5 integrated with SINAMICS S120 or CU320) can be found in the previous section.
The drive unit (SINAMICS) and the SIMATIC F-CPU are located on different PROFIBUS subnets. In this case, a PROFIsafe router to SIMOTION D is configured so that the necessary data is copied from one network to the other.
Configuring PROFIsafe communication
The next sections describe the configuration of PROFIsafe communication between a SIMATIC F-CPU and a drive object of an integrated SINAMICS drive unit of a SIMOTION D.
The procedure for configuring PROFIsafe communication between a drive unit of a CU320 and a SIMATIC F-CPU is basically the same and is not covered separately.
1. Create an F-CPU (e.g. CPU 317F-2) and a SIMOTION D4x5 controller (with integrated SINAMICS S120) in accordance with the hardware installed.
2. Define a SIMOTION CPU for operation as DP slave and the F-CPU as associated DP master.
3. Configure the SINAMICS drive unit in SIMOTION SCOUT in accordance with your hardware configuration.
4. Then insert a new TO axis and run through the axis wizard. In the wizard, interconnect the axis to the corresponding drive object of the S120 and a corresponding telegram will automatically be created (symbolic assignment).
5. Save and compile the project.
6. Create a PROFIsafe slot in the configuration of the SINAMICS drive unit.
For this purpose, select in tab IF1 the following: PROFIdrive PZD message frames - the drive object which is to communicate with the SIMATIC F-CPU via PROFIsafe. Click on the Adapt message frame configuration button and select Add PROFIsafe.

Figure 9-44 PROFIBUS message frame 7. Save and compile the project.
8. Transfer the new PROFIsafe slot to HW Config by clicking on the Set up address button.
9. In HW Config for the F-CPU, connect the preconfigured SIMOTION station to the F-CPU (hardware catalog: PROFIBUS DP > Preconfigured stations ...).
Note
To configure the SINAMICS Safety Integrated extended functions by means of SIMOTION, the message frames must be extended. To do so, a safety data block is appended to the PROFIdrive actual value message frame. Configuration and parameter assignment of this Safety data block are described in the Function Manual SIMOTION Motion Control TO Axis electric/hydraulic, external encoder.
10.You can display the F-communication parameters via the DP slave properties (double-click on SIMOTION I-slave). To do this, go to the F configuration tab and click on New.
Mode: Displays the communication relationship. F-MS module represents safety-related master-slave communication with SIMOTION.
DP partner (F I/O): SINAMICS drive properties.
Here you can select the relevant PROFIsafe drive via DP address or Address.
local: Properties of the SIMOTION CPU.
Enter the logical start address for F-communication of the SIMOTION CPU in the "Address"
row.The address space for sending and receiving the safety frames depends on the message frame used and must be located outside the process image of the SIMOTION CPU ( >=
64).Master (safety program): SIMATIC F-CPU properties.
The logical start address for F communication of the SIMATIC F-CPU must be entered here under "Address" (LADDR).
The address space for sending and receiving safety message frames depends on the message frame used and must lie within the process image of the SIMATIC F CPU.
In the SIMATIC F-CPU safety program, this address space can be used to access the PROFIsafe control or status words.
An overview of which message frames are possible for the individual drives can be found in the SIMOTION FAQs.
11.Open the SIMOTION CPU project in HW Config.

12.Double-click on the icon of the SINAMICS drive unit and select the Details tab in the Configuration tab.

13.Click on the PROFIsafe… button and then define the F parameters which are important to F communication. As of STEP7 V5.5, PROFIsafe V2 is used by default.
(If the PROFIsafe… button cannot be used, you need to activate it using the Activate...
button.)
For more information about the fail-safe parameters, see PROFIsafe properties for configuration (Page 273)

14.Compile HW Config of the SIMOTION CPU. Compile the F-CPU configuration data in HW Config.
Note
For information about creating a safety program and accessing PROFIsafe useful data (e.g STW and ZSW) within the safety program, refer to the SIMATIC, S7 Distributed Safety - Configuring and Programming Programming and Operating Manual.
Safety configuration (online) in the SINAMICS drive
1. Call the configuration for Safety Integrated by selecting "Functions" at the SINAMICS drive entry in the tree structure.
2. Configure Safety Integrated and set to hex representation the F_Dest_Add parameter already defined under the drive's PROFIsafe address (p9610/p9810).
3. Finally, perform a POWER ON. The safety configuration is now active in the drive.
