Creating A New Profibus Subnet - Siemens SIMOTION D4x5-2 Commissioning And Hardware Installation Manual

As of SIMOTION version V4.5, the following SIMOTION D Control Units can also be operated
with a DP Integrated with 250 µs and 375 µs:
● SIMOTION D435-2 DP/PN
● SIMOTION D445-2 DP/PN
● SIMOTION D455-2 DP/PN
Configuration rules
The following configuration rules must be taken into account when using DP Integrated cycle
clocks < 0.5 ms:
● Simultaneous use of Servo_fast and IPO_fast with DP Integrated cycle clocks < 0.5 ms is
not possible because the resulting cycle clock ratios violate the rules for the use of
Servo_fast and IPO_fast.
See also Section Setting of the cycle clocks (two servos activated) (Page 154)
● If the SINAMICS Integrated is operated with a DP Integrated cycle clock of 250 μs or 375
μs, this results in a higher utilization on the drive side in comparison to a cycle clock of ≥
500 μs. Depending on the utilization situation (e.g. through ALM, CXs, TMs, etc.), this can
result in a reduction in the number of axes (e.g. from six to five servo drives). It can also
result in a reduction of the quantity structure for vector and V/f-controlled drives.
● CBE30 supports a minimum send cycle clock of 500 μs. The SINAMICS Integrated can
therefore only be operated with 250 µs or 375 µs if isochronous communication has not
been configured for the CBE30.

Creating a new PROFIBUS subnet

Introduction
SIMOTION SCOUT is used to network the SIMOTION D4x5‑2. During the configuration
process, the desired bus parameters can be set for the PROFIBUS DP interfaces.
Note
If a hardware configuration is loaded without a PROFIBUS network (X126 or X136) being
configured on the CPU, a new PROFIBUS address that was previously set in HW Config or
NETPro will not be accepted by the CPU.
Requirement
You have created a project and have inserted a SIMOTION D4x5‑2.
