Siemens SIMOTION D4x5-2 User Manual

You set these PROFIBUS addresses individually for each device with the PG/PC using HW
Config. Some PROFIBUS DP slaves have a switch for this purpose.
Note
The PROFIBUS addresses set at the devices using these switches must correspond with the
address settings in HW Config.
Recommendation for PROFIBUS addresses
Reserve
PROFIBUS address "0" for a service programming device and "1" for a service HMI
device, which will be connected to the subnet if required.
Recommendation for the PROFIBUS address of the SIMOTION D4x5‑2 in case of replacement
or service:
Reserve address "2" for a SIMOTION D4x5‑2. This prevents duplicate addresses when
installing a SIMOTION D4x5‑2 with a default setting on the subnet (e.g. when a
SIMOTION D4x5-2 is replaced). You should therefore assign addresses greater than "2" to
additional units on the subnet.
6.3.4 Setting the DP cycle and system cycle clocks
All cycle clocks for the SIMOTION D4x5‑2 are based on the DP cycle of SINAMICS Integrated,
which must be set in HW Config.
To do so, click the SINAMICS block on the integrated PROFIBUS. The "DP Slave Properties"
dialog box opens. You can adjust the DP cycle of the SINAMICS Integrated on the
"Isochronous mode" tab.

SINAMICS Integrated always runs in isochronous mode. The DP cycle setting of the
SINAMICS
Integrated is displayed as the "Bus data cycle" in the "System Cycle Clocks" dialog
box. In SIMOTION SCOUT, select the SIMOTION D Control Unit and then select the "Set
system cycle clocks" option in the "Target system" > "Expert" menu.
