ABB FENA-11 - Example 5: Determining the Source of the Process Data Read from the Drive

350 PROFINET IO – Communication protocol
Example 5: Determining the source of the process data read
from the drive
PROFIdrive parameter 916 (394h) can be used to define which
data is read cyclically from the drive as application-specific process
data. In the example below, the parameter is used to determine
which drive parameter the contents of PZD3 are taken from.
Subindex (IND) defines which process data word the required data
is transmitted in.
