S300-S400-S600-S700 PROFIBUS | 4 Device profile
4 Device profile
The PROFIBUS profile PROFIDRIVE includes the following parameter process-data objects
(PPO):
The servo amplifier only uses the PPO-type 2 (with 4 words PKW-section and 6 words PZD-sec-
tion). The PKW-section is used mainly for the transmission of parameters for the servo amplifier,
the PZD-section is used principally for handling motion functions.
The telegram can be divided into two sections or data channels:
1. PKW section (4 words, Bytes 1 to 8)
2. PZD section (6 words, Bytes 8 to 20)
The PKW data channel can also be termed the service or parameter channel. The service chan-
nel only uses confirmed communication services, and is used by the servo amplifier as a para-
meter channel.
The PKW channel has no real-time capability.
The PZD data channel can also be termed the process data channel. The process data channel
uses unconfirmed communication services. The response of the servo amplifier to an unconfirmed
service can only be seen in the reaction of the amplifier (status word, actual values).
The PZD channel has real-time capability.
