Selection of the PROFINET variant

PROFINET variants
The PROFINET variant for the PROFINET interface can be selected as of SINAMICS
firmware version 2.5 SP1 Hotfix 10.
Only one of the available PROFINET variants can be loaded as firmware at any one time to
the Control Unit. All firmware files provided for different PROFINET variants are stored on
the Control Unit's memory card.
The different PROFINET variants are listed below:
● PROFINET version 2.1 (RT class IRT*)
● PROFINET version 2.2 (RT class IRT)
● Customized
The PROFINET variants required are each stored in a separate UFW file on the memory
card. The pointer file OPTBOARD.INF contains the names of the UFW files to be loaded.
The contents of the pointer file are modified in order to switch from one firmware variant to
another. POWER ON must then be executed to activate the change in variant. During the
subsequent system boot, the UFW file referenced in the pointer file is loaded.
The pointer file refers to PROFINET V2.2 by default.

The new parameter (p8835) available as of firmware version 2.6 can be used to modify/read
the content of the pointer file OPTBOARD.INF. This file must be edited manually with other
firmware versions. The default value PROFINET is p8835 = (1).
Indices of p8835:
0 = PROFINET V2.1
1 = PROFINET V2.2
99 = Customized
Writing the parameter modifies the content of file OPTBOARD.INF as long as the written
value corresponds to a firmware variant on the card.
Reading the parameter displays the content of file OPTBOARD.INF.
Modifying the parameter effects switchover between the different variants. A POWER ON
must then be performed to activate the change.
Identification of firmware variant:
The OMI diagnostic channel (r8858) can be read to identify which firmware variant of
PROFINET interface is currently loaded.
