Need to perform arbitrary time-dependent speed profile

Hi, 

I successfully applied the above method for square wave type velocity profile. Now I need to perform arbitrary time-dependent speed profile. Do I need to use any Technology Object of the drive or PLC. The final axis to be speed-regulated is on the motor shaft and feedback element is the encoder on the motor shaft.

Do have any recommendation for high-performance speed control?
What about S7-1500T? Do I need it for Profinet IRT?  

Thanks

Split from Best method for performing given time based velocity profile .

for the drive it isn´t important, where you get the speed setpoint (from internal ramp generator, by DCC- logic,  or by a PLC).

A lot of test stands works with SINAMICS S120, because of it´s high torque and speed controller band width.  There you use profiles, which are calculated by a PLC too (and connected by PROFINET IRT or ETHERCAT).
