Change drive parameters from PLC

Hello all,

I have sinamics drive G120C connected to PLC and HMI, I knew from this manual that if I want to change any parameter (like ramp time) from HMI, I can use the following command 

DB<parameter number>.DB<a>data block offset   a=B│W│D  as shown in the attached picture. 

Is this also possible in the PLC, for example I move a value to same address that shown in the picture?

Yes, it's possible to read/write drive parameters from PLC program. No, those addresses only work with HMI.

Thank you for your answer, 

then how can I read/write them from PLC?

Thanks again

Update: I want to read/write any parameter outside the telegram.

You can use:

• SINA_PARA (one parameter) and SINA_PARAS (several parameters)
  This FBs are part of the DriveLib, which is part of Startdrive or can be downloaded at https://support.industry.siemens.com/cs/ww/en/view/109475044
  At this link a manual is provided too.
  
  
• WRREC (and RDREC) (Write and read record, acyclic communication)
  This is with less overhead, bit more difficult. The SINA_PARA uses this functions too.
  For details look into a SINAMICS manual under acyclic communication.
