1)
PROFIBUS with PROFIsafe:
If SIMOTION D is operated as an intelligent DP slave on an F-CPU, a maximum of 32 safety slots can be configured for
each intelligent DP slave in HW Config. If the Safety Integrated functions are controlled via PROFIBUS with PROFIsafe,
one slot in the input area and one slot in the output area are used for each safety axis. This results in a maximum of 16
drives with the Safety Integrated function for each PROFIBUS interface (intelligent DP slave) of the D4x5‑2. If with
SIMOTION D both PROFIBUS interfaces are operated as an intelligent DP slave on a F‑CPU, the quantity structure
increases to 2 x 16 drives (sum of the drives on the SINAMICS Integrated, CX32‑2 and SINAMICS Control Units). In this
case however, no PROFIBUS master interface is available for the connection of I/Os, for example.
2)
PROFINET with PROFIsafe:
The maximum permissible quantity structure for the D4x5‑2 is max. 128 drives depending on the Control Unit (< V4.2 SP1
HF1: 42 drives; V4.2 SP1 HF1 to V4.4: 64 drives) with Safety Integrated function (sum of drives on SINAMICS Integrated,
CX32‑2 and SINAMICS Control Units).

Also with CX32-2 connected to D4x5-2
The maximum drive quantity structure depends on other factors. For example with T
I
= 125 µs,
maximum of four Motor Modules may be operated with Safety Integrated Extended/Advanced
Functions on a DRIVE-CLiQ line. Additional drive components (e.g. Line Modules, Terminal
Modules, encoders, etc.) can also reduce the maximum drive quantity structure.
Recommendation:
With the SIZER configuration tool, you can easily configure the SINAMICS S110/120 drive
family including SIMOTION.

Use of two PROFINET interfaces
An F-CPU can only be connected to one of the two PROFINET interfaces, because fail-safe
I/O transfer areas can only be configured either on the I-device on the onboard PROFINET
interface or on the CBE30-2.
The PROFIsafe telegrams are routed to the following drives:
● Drives on the SINAMICS Integrated and CX32-2
● Drives on the onboard PROFINET interface (X150 interface)
● Drives on the CBE30-2 (X1400 interface)
The maximum quantity structure for PROFIsafe on PROFINET is therefore not increased by
using a second PROFINET interface.
