Setting the Bus Parameters and Profiles
The Baud rate can be set in the Settings > Bus Parameters menu. Furthermore, the optimising or profile
can be selected.
Figure 14: Settings > Bus Parameters
The Bus Parameters may be viewed with the Settings > Bus Parameters menu and may be edited by
clicking on the Edit button. The Bus Parameters may or may not be edited depending upon the optimising or
profile selected. The optimising standard provides each Baud rate with default Bus Parameters for
PROFIBUS-DP systems. By changing the settings in the Optimising field from Standard to User defined,
all Bus Parameters may be edited.
