PROFINET IO – Communication protocol 95
• DP-V1 Read response:
Value indicates the source of PZD3 as drive parameter 12.05
(0C.05h).
Diagnostic and alarm mechanism
The FENA adapter module has mechanisms for sending alarms
and saving diagnostics data to a fault buffer. An alarm is triggered
if the host or drive has faults in communication or operation. The
alarm and fault buffer mechanisms are enabled by default and can
be disabled with a configuration parameter (21 Alarm disable on
page 13).

The slave returns the product code of the drive (20Bh in this example).
Example 4: Configuring the process data written to the drive
PROFIdrive parameter 915 (393h) can be used to define which data is written cyclically to
a drive parameter as application-specific process data.
In the example below, the value of drive parameter 12.06 (0C.06h) is selected to be taken
from PZD3. The parameter will continue to be updated with the contents of PZD3 in each
Request frame until a different selection is made.
Subindex (IND) defines which process data word the required data is taken from. Value
selects the drive parameter to which that word is mapped.
