Modifying the data transmission rate

Introduction
You can modify the transmission rate in a PROFIBUS subnet in HW Config according to
your requirements.
Procedure
1. Open the project in SIMOTION SCOUT.
2. Double-click the device whose PROFIBUS subnet you want to configure.
3. In HW Config, double-click in the graphical display on the PROFIBUS network whose
4. Click on "Properties" to display the "PROFIBUS Properties" dialog.
5. Select the required transmission rate on the "Network settings" tab.
6. Confirm with "OK".
7. Save and compile the new hardware configuration, and load it on the SIMOTION D.
Note
If you modify the transmission rate of the subnet over which you are operating the PG/PC,
the PG/PC loses its active designation. You must then reconfigure it manually in NetPro or
else you will no longer be able to go online by means of this PG/PC.
Note
PROFIBUS DP functionality is both equidistant and isochronous in nature. As such, it can
guarantee that bus cycles will have exactly the same length and ensures deterministic
behavior.
Applications: Connecting drives or synchronized I/O devices.
