How PZD protocol work? The S7-CPU and Sinamics can or use a communication with Profibus or Profinet. Both systems are bus connection with a detailed description how a Master and Slaves have to communicate using a special physical envinronment. A telegramm between Master and Slave is seperated in several PZD - in several words - where the user has to put in the information for the slave (drive) and where he gets the status informations. In a List manual for Sinamics S120 you can find a description about the available telegram and their PZD built order. If you select the right telegram in S7-CPU and in the drive then it is clear which information you have to send and which information you can receive. The standard functions SFC14/15 can be used for a telegram communication . A Shah Pattern Description of PZD12/12 used for axis, Means which data is available in PZD 12/12 Have a look on the list manual. A Shah Thanks in advance

Control Word(PLC to Drive): STW1,STW2,... Status Word(Drive to PLC): ZSW1,ZSW2,... PZD (telegram)selection depends upon your application. weather you want to run your motors with speed control with or without encoder, position control... kindly refer 1LH1.pdf.. if you select telegram 2, PZD 4x4,.. means 4 wordssends data of PLC to Drive and 4 Words are received on PLC from Drive. Ex.. (toolbox program) In FC71 atWR_PZD and RD_PZD you have to write exact PZD words as per telgram.

This datablock and its informations -which the user is changing in his standard programm - is send via for example SFC14/15 to the drive. If you want to change a parameter which is NOT part of your cyclic transfer - because this parameter is a configuration parameter - then you are using an acyclic communication with for example SFC 52/53. Additional informations can be found here (chapter 10"communication"): http://support.automation.siemens.com/WW/view/en/68042590

Status Word(Drive to PLC): ZSW1,ZSW2,... I believe PZD is an abbreviation of the German wordProzessdaten (Process Data). STW is an abbreviation of the German wordSteuerwort (Control Word). ZSW is an abbreviation of the German wordsZustand Steuerwort (Status Word). Can anyone confirm this please? Thanks!
