Procedure
1. When you set the device name, e.g. Safety Relay 1, in your automation software, STEP 7
automatically assigns the IP parameters. These can be individually adapted in the automation
software.
2. Assign the device name based on the MAC address of the PROFINET interface.
3. Load the conguration into the IO controller.
4. The IO controller writes the IP parameters based on the device name during startup.
Note
Deleting IP parameters
IP parameters assigned by the IO controller are stored non-retentively in the device, i.e. they are
deleted again when the supply voltage is switched o. When it is started up again, they are
loaded to the PROFINET interface by the IO controller once more.
Result
The device communicates with the assigned name and the IP parameters assigned by the IO
controller.
Note
If the IP parameters are assigned by the IO controller, the IP address, subnet mask and router
address are set to the value 0.0.0.0 in the basic unit.
If the IP address then has to be assigned by the PROFINET interface again, the IP parameters have
to be transferred to the device once more.
6.6.2 Conguring in STEP 7 with GSD le
Requirements
You need a GSD le for the PROFINET interface, which you can download from the Internet
(
https://support.industry.siemens.com/cs/ww/en/view/38702563).
Using the GSD, integration into the PROFINET IO system and device diagnostics are possible. Use
the SIRIUS Safety ES parameterization software to parameterize the device function.
The GSD is available for downloading at the following link: PROFINET GSD. (https://
support.industry.siemens.com/cs/products?dtp=Download&mfn=ps&pnid=14288&lc=en-WW)
Note
The specication version used in the GSD le is specied in the le name. Make sure that the
engineering system supports this or a newer version of the specication. Example: GSD-V2.33-
SIEMENS-SIRIUS_3SK2PN-yymmdd.xml.
