What's new in the PROFINET function manual, version 12/2017 compared to version 09/2016
This manual (version 12/2017) encompasses the following new functions compared to the
previous version (version 09/2016):
Function Applications Your benefits
Specifying the router
for a PROFINET IO
device
You can specify the IP address of a router for
each IO device. You reach the IO device from
outside the IP subnet through the router.
In the past, it was only possible to specify a router
for a PROFINET IO interface at the IO controller.
The IO devices inherited the setting of the IO
controller interface.
Now you can set the router address independent-
ly of the IO controller setting. This allows, for
example, a router address at the IO device alt-
hough you have not set a router address or have
set a different address at the IO controller.
Configuring an IO
device through hard-
ware detection
You can detect an existing IO device and enter
it in your project.
STEP 7 inserts the IO device with all the modules
and submodules into the project. Article numbers
and firmware versions between real and config-
ured IO devices match.
You reduce the project planning work required.
Asset management You can centrally manage non-PROFINET com-
ponents (assets) of a PROFINET device. The
PROFINET device makes the identification data
of the assets available for evaluation via a
standardized data record.
The new standardized PROFINET service makes it
possible to manage all the hardware and firm-
ware components of PROFINET devices centrally.
The possibilities available for filtering device data,
for example, depend on the range of perfor-
mance of the evaluating application.
Asset manage-
ment data record for I-
devices
Special application of asset management: From
the point of view of a higher-level IO controller,
the modules plugged into the I-device repre-
sent assets. The user program in the I-device
compiles the asset management data record.
The IO controller can read identification data of
the I-device modules through this data record.
