The OP mentions PROFINET, not PROFIBUS.
When i drag a PPO in PROFIBUS it creates IO address for the PKW data + PZD etc.
When i drag a PPO in PROFINET there is no IO address for the PKW data created, just for the PZD.

So how does one use the PKW functions in PROFINET?

Hello arifinsabuz;

The terms PZD (German initials for "Process Data") and PKW (German initials for "Parameter Values") are used in the description of the ProfiDrive profile; in other words, they are part of the description of communications between a CPU and a drive, using Profibus or Profinet.

Which terminology do you use for cyclic ProfiDrive communication?

- PZD is an area of the Profibus/Profinet telegram used to exchange data between the drive and the controller cyclically: control word, status word, speed setpoint, speed status, torque, etc...

- PKW is a seperate area designed for the reading and writing of single parameters on the drive; it is operted acyclically, which means you must use DP_RDDat (SFC_15) and DP_WRDat (SFC 14) functions to transmit the information between the controller and the drive..

The following documents have very good descriptions of PZD and PKW mechanisms, along with examples and samples:

- Operation instructions: MicroMaster Profibus optional Board

- MICROMASTER 4 (MM4), SINAMICS G120 (CU240S/D, DP/DP-F, PN/PN-F): Essentials for PROFIBUS and PKW-mechanism.

Hope this helps,

Split from Meaning of PPO, PZD and PKW.

It depends on the PPO type (Telegram type) What I/O areas it will define to the drive.

 None of the PPO's have PKW data in them (ABB ACQ###) drives.

 Have you checked from the ABB manuals If it's possible and how to do it?
