Setting PPO Type

13 Setting PPO Type
As a function of the application in question, various process peripheral objects (PPOs) with differing
lengths and contents are used for data exchange. The CM-PDPV1 offers a wide range of PPO settings.
With the help of a hardware configuration tool the user is able to construct PPO settings as needed for
his application.
Four predefined objects PPO1, PPO2, PPO3 and PPO4 and two additional objects (communication
object PKW, process data object PZD) are available for free configuration.
The required object is to be set on the DP master in the hardware configuration. There is no setting for
the required object on the side of the frequency inverter; it sets itself automatically to the projected
object.
Note: Further information on the contents of the objects is described in Chapter 16 "Handling of
the Objects".
The PKW object is used for accessing parameters (read/write) in the inverter. This object
causes additional busload because it sends its contents with every data exchange cycle,
whether it is used or not. As an alternative function without the necessity of the PKW
object, the CM-PDPV1 module supports the DP-V1 channel. This function is explained in
Chapter 16.2 "Parameter Access via the DP-V1 Channel".
Each PZD object has two words of input/output data. The handling of this object is
explained in chapter 16.3.1 "Data Types of OUT/IN-Objects".
