Conguring the PROFINET interface as a PROFINET IO device
The PROFINET interface is congured as a PROFINET IO device with the conguring tool of the
PROFINET IO controller (e.g. STEP 7). The properties (device name and the process data structure
width 32-bit/64-bit) set in the conguring tool must be identical to the properties set in SIRIUS
Safety ES. Otherwise, no communication can be established.
WARNING
Hazardous system state due to unauthorized access via eldbus
Can Cause Death, Serious Injury, or Property Damage.
Unauthorized access to the safety relay via the eldbus (PROFINET or PROFIBUS) can enable
conguration changes and overriding of safety functions.
To prevent unauthorized access to the safety relay via the eldbus network, assign a password
for accessing the device in Safety ES. If you operate several safety relays in one eldbus
network, you must assign a separate password for each safety relay to prevent confusion when
accessing via the eldbus. In other words, the passwords must not be identical.
Installation of the GSD le with STEP 7
You can nd out how to install the GSD le in the Online Help of STEP 7.
After installation of the GSD, you will nd the PROFINET interface in the hardware catalog of
STEP 7 V5 under "HW Catalog" > "Other Field Devices" >"PROFINET IO" > "Switching Devices" >
"Siemens AG" > "Safety Switching Devices". Insert the PROFINET interface into the PROFINET IO
system.
6.6.3 Failure and restoration in the case of PROFINET
PROFINET failure
The PROFINET interface reports a PROFINET interruption to the safety relay. The safety relay then
uses the substitute value "0" for the PROFINET logic inputs. Safety mode is not exited. The bus
failure can also be diagnosed in SIRIUS Safety ES.
