￭ Behavior of output data
Then If
Output data retains last values IOPS (PLC provider status)=Bad
Output data retains last values Connection loss
All output data is 0 After power-up
Parameter handling using acyclic parameter access
mechanism (DP-V1)
PROFINET IO offers record read and write services for the acyclic parameter access
mechanism. When the drive parameters or FSPS-21 parameters are accessed, the
corresponding slot, sub-slot and index are set, and a PROFIdrive DP-V1 message is placed
on the data block of the record read or write frame.
￭ Header and frame structures
PROFINET IO uses the DCE RPC (Distributed Computing Environment Remote Procedure
Call) protocol for acyclic read and write services. I/O controllers and supervisors take care
of formulating most of the request frames. However, it is possible that handling the
PROFIdrive request and response headers must be performed in the application logic. The
acyclic frame structure, headers and error codes are described further below.

Dest addr. and Src addr. are the destination and the source of the communication
relationship. The addresses are in hexadecimal format, for example, 00-30-11-02-57-AD.
Ether type is 0x800 for non-real-time communication.
