11 Process data description
11.1 General process sequence
The process sequence that is exchanged between the fieldbus master and the device
depends on the device type.
The following figures show the process sequences between fieldbus master and
device. The following abbreviations are used in the figures:
Term Abbrevi-
ation
Digital input DI
Digital output DO
Process data PD
Process input data word PI
Process output data word PO

In the case of MOVIPRO
®
SDC, the process data interface is already preset and spe-
cified. You only have to choose the drive function of the power section "PFA-..." to
match your requirements.
A maximum of 8 process data words is permitted to be exchanged between fieldbus
master and MOVIPRO
®
SDC.
The process sequence of MOVIPRO
®
SDC is essentially divided into 2parts:
• SEWController (fixed):
– MOVIPRO
®
control word/MOVIPRO
®
status word
– Digital inputs/digital outputs (DI/DO)
• Drive function (parameterizable):
– Control word/status word of the power section
– Setpoints/actual values
– Application data, such as position, speed, etc.
