You can only use the internal DP interfaces of the CPUs for clock-synchronized communication with PROFIBUS DP.
You can use STEP 7 V5.2 and higher or TIA Portal for configuring.

The clock synchronicity is also supported by the complete product group "SIMODRIVE 611U", "SINAMICS" and "MASTERDRIVE MC". The following are required in order to configure the drives: Drive ES Basic V5.2 or higher, STEP 7 V5.2 or higher and one of the CPUs mentioned above.
