Configuration and Parameter Assignment
Bus Parameter Settings for PROFIBUS DP
To comply with the values for electromagnetic compatibility, if you are using
transmission rates less than 6 Mbps, you must increase the bus parameter
"Retry Limit" to at least "3". Leave all other bus parameter default settings for the
bus profile you are using.
Follow the steps outlined below in HW Config:
1. Open the "General" tab and select Properties > "Network Settings" tab in the
DP master system.
3. Set "User-defined" in the Profile.
4. Select the Bus parameters and increase the "Retry Limit" from "1" to "3".
5. Exit the Bus Parameters dialog with "OK".
6. Open the Bus Parameters dialog again.
7. Click the Recalculate button.
8. Exit the Bus Parameters dialog with "OK".
Note
Remember that whenever you make a change to the DP master system (for
example adding a new DP slave), you must subsequently click on the
Recalculate button in the Bus Parameters dialog.
If you change to a transmission rate higher than 6 Mbps, you should set the "DP"
bus profile again.
