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 consistent is dragged and dropped to the first

slot.

See the PPO types section in How to Control the Adjustable Frequency Drive

for more information.

The configuration tool automatically assigns addresses in the peripheral address area. In this example, the input and output area have the following configura-

tion:

PPO type 6:

PCD word number

Input address

Set-up

3.1: PCD read (Drive to PLC)

PCD word number

Output address

Set-up

3.2: PCD write (PLC to Drive)

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

( PB-15 PCD Write Configuration and PB-16 PCD Read Configuration) from the PLC/Master. To use Autoconfig, make sure the feature under DP slave Properties

is enabled.

NOTE

DP V1 diagnostics is supported for Profibus SW version 2 and higher. This means that the default setting of the Profibus option is DP V1 diagnostics. If DP V0

diagnostics are required, the setting under DP slave Properties must be changed

Download the configuration file to the PLC. The PROFIBUS system should be able to go online and it will start to exchange data when the PLC is set to run

mode.
