EXPLANATION--> A PPO consist of parameter portion
(PCV/PKW) and process data portion (PCD/PZD). The PCV part
is used for reading and/or updating of parameters. It is futher
devided into PCA, IND and PVA.The PCA defines what you
would like to do with parameters. IND is only used for accessing
the arrayed parameters.The PVA holds the data you are writing
to a parameter or a data you are reading from the parameters.
The PCD portion consist of fixed part (4 bytes) and a
parameterizable part (8 or 16 bytes). The CTW and MRV are
transmitted to the frequency converter in the fixed portion,
whereas the STW and MAV are transmitted by the frequency
PCD → PROCESS DATA
STW → STATUS WORD(FromDrive)
CTW → CONTROL WORD (To drive)
converter.
In the parameterizable portion the user select which parameter
are to be transmitted to the frequency converter and which are to
be transmitted by the frequency converter

MRV
IN SIEMENS PCV IS EQUIVALENT TO PKW AND PCD EQUIVQLENT TO PZD.
