DP-V1 communication

The extended Parameter Data bytes are configured via the
PROFIBUS network configuration tool. The functions are defined
in the GSD file.
SAP 62 (Chk_Cfg)
SAP 62 selects the PPO type to be used. The table below gives
the Hex values that must be sent to the drive to select the PPO
type.
*PKW: “Parameter-Kennung-Wert” (Parameter ID Value)
**PZD: “Prozeßdaten” (Process data)
With PPO1, PPO2 and PPO5, reading/writing parameters is only
possible cyclically through the Parameter Identification (PKW)
channel. With PPO3, PPO4 or PPO6, acyclic parameter
reading/writing is available via the DP-V1 parameter read/write
service.
The PPO type can be changed during runtime. However, the
RPBA-01 will go offline while the configuration is being updated.
