5.2.2.3
Transfer of data record via PPO 1 and PPO 2
PPO1 and PPO2 objects are supported in order to simplify the conversion of an existing PROFIBUS DP
system to a PROFINET IO system. In addition to the cyclical IO data, there are also the acyclical parameter
data (see Section 5.2.4.4).

5.2.3.1
Order label field
The following table lists all the orders which can be transferred from the PROFINET IO controller to the
frequency inverter. The right-hand column contains the response, which is normally sent (response label
positive). Only certain response labels are possible, depending on the order label. In case of error (AK
negative) the inverter will always supply the value 7 in the response label (AK) to the IO controller.

Table 23 Orders from the controller with the associated response label of the inverter
The following table lists all the orders which can be transferred from the controller to the frequency inverter or
the technology units. The right-hand column contains the response, which is normally sent (response label
positive). Only certain response labels are possible, depending on the order label. In case of error (AK
negative) the inverter always supplies the value 7 in the response label (AK) to the PROFINET IO controller.
