Operating instructions

The next step is to set up the peripheral input

and output data. Data set up in the peripheral

area is transmitted cyclically via PPO types. In

the example below, a PPO type 6 Word con-

sistent is dragged and dropped to the first slot.

See the PPO types section in

How to Control

the Frequency Converter

for more informa-

tion.

The configuration tool automatically assigns addresses in the peripheral address area. In this ex-

ample the input and output area have the following configuration:

PPO type 6:

For Profibus SW version 2.x and higher, Auto-configuration of process data is supported. This

feature makes it possible to configure the process data (par. 9-15 and 9-16) from the PLC/Master.

To use Autoconfig, make sure the feature under
