5. Using the "Bus Parameters" button you can check the bus parameters for the PROFIBUS
networks and adapt these as necessary once you are working with the user-defined profile.
The parameters are updated each time you add another DP slave. The default option "Turn
on cyclic distribution of the bus parameters" must be selected.
The "Ttr" (target rotation time) value is included in the calculation of the monitoring times
for the H system. The parameter "Retry Limit" should be increased to 3 for ring structures
with Profibus OLM.
6. The "H Parameters" tab is only available when a redundant system is used.
