5.6 Configuring PROFINET IO
SIMOTION D4x5-2
150 Commissioning and Hardware Installation Manual, 02/2012
● 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 message frames 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.
● If Servo_fast is not used, the servo isochronous devices can be assigned to both
PROFINET interfaces.
● A redundant sync master is not permitted in the SYNC domain of the onboard PROFINET
interface if both PROFINET interfaces are operated isochronously and the CBE30-2 is
configured as a sync slave or IRT I device.
Rules for Servo_fast
The following rules apply for the onboard PROFINET interface (X150) assigned to the
Servo_fast:
● The interfaces are permanently assigned:
– Servo/IPO/IPO_2 to the CBE30-2 (or DP and DP Integrated)
– Servo_fast and IPO_fast to the onboard PROFINET interface
● If the Servo_fast is used, only one CACF (Controller Application Cycle Factor) = 1 is
permitted for Servo and Servo_fast, i.e. it must be set:
– Servo cycle clock = send cycle clock of the PROFINET interface X1400 (CBE30-2)
– Servo_fast cycle clock = send cycle clock of the PROFINET interface X150 (onboard
interface)
● The Servo_fast must have a reduction ratio to the Servo of 2, 4, 8, or 16.
