The PPO selection can be subdivided into:
Net data without parameter area
with 2 to 16 words for the process data.
and
Net data with parameter area
with 2 to 16 words for the process data.
These are the PPO types 1, 2 and 5.
A different number of process data is permissible for the setpoints and
actual values (from SW 3.1).
In addition to be able to freely set the number of process data, the con-
figuring allows standard settings to be selected. This includes, in addi-
tion to the PPO types PPO1 to PPO5 (refer to Table 5-1) a whole se-
ries of configured functions (GSD file, Drive ES), which are suitable for
the various standard telegrams.

Notice
The five various PPOs are selected with different data length
depending on the task that the drive has to fulfill in the automation
environment.
The process data structure of the telegram can be defined and configu-
red as follows from SW 3.1:
By selecting a standard telegram
By freely configuring a telegram
