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?https://support.industry.siemens.com/cs/ww/en/view/24184004 - 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 https://support.industry.siemens.com/cs/ww/en/view/6586565 - MICROMASTER 4 (MM4), SINAMICS G120 (CU240S/D, DP/DP-F, PN/PN-F): Essentials for PROFIBUS and PKW-mechanism. https://support.industry.siemens.com/cs/ww/en/view/8894584 Hope this helps, Daniel Chartier |
