Process Data Overview
The basic serial interface on the keypad operator consists of four containers
for incoming data (PDI - Process Data In) and four containers for outgoing
data (PDO - Process Data Out).
Depending on the DIN66019II service used, the string of PDI data from the
telegram will be deposited into two or more of the containers. The containers
are then mapped (FB17-20) to a defined function (eg. Control Word, Speed,
Pretorque, Absolute Target Position) with the function structure also defined.
Depending on the function, the raw PDI data (FB34-37) may be scaled or
masked (FB05-07) before being processed by the drive (FB01-04).
The PDO data will originate from the DG parameters in the operator (viewable
from Combivis). This data will be mapped (FB13-16) to the four PDO containers
and then depending on the service, taken from the container and placed in
the response telegram (FB30-33).

For the PDI, there are four fixed-functions established, each with a
corresponding structure definition: Control Word, Speed, Pretorque, and
Absolute Target Position.
