PROFINET IO-Controller Firmware Versions V2 and V3
The PROFINET IO-Controller firmware has been revised and completed
and is available in version V3 since the first quarter of 2017.
Upgrading the PROFINET IO-Controller firmware from V2 to V3 is
recommended. Use the PROFINET IO-Controller firmware V3 for a new
installation when creating or developing your application program for the
first time.
The development of the PROFINET IO-Controller firmware V2 will not be
continued. But this firmware version is still maintained and will be delivered
furthermore.
The PROFINET IO-Controller V3 implements several new features, which
are not available in the PROFNET IO-Controller V2:
•
IRT operating mode
•
Optimized process data performance
•
Automatic name assignment
•
Automatic alarm acknowledgement
•
MRP Client and Manager for media redundancy
•
Requirements PROFINET Specification 2.3: e. g. Advanced Startup,
MultipleInterfaceMode, network load requirements.
The process data handling in PROFINET IO-Controller V3 (process data
image structure and process data timing) was reworked to achieve the
required performance improvement and to support synchronized
applications.
Removed features and incompatibilites:
•
PROFINET IO-Controller V3 does neither support swapping of IO data
nor automatic IOPS handling.
•
The configuration parameters have been extended to meet the IRT
configuration requirements. The structure of the configuration database
has been changed. Therefore, the PROFINET IO-Controller V3 can not
be configured with a configuration database of the PROFINET IO-
Controller V2 and vice versa.
•
The configuration API of PROFINET IO-Controller V2 are not supported
by PROFINET IO-Controller V3. The new configuration API of
PROFINET IO-Controller V3 is to be used.
•
The PROFINET IO-Controller V3 does not support process data in little
endian format. This feature was rarely used and has been removed for
better performance.
