6.4 Integrating into DP master systems
6.4.1 DP address of the DP interface
Options for setting the DP address
The DP interface oers three ways of setting and changing the DP address:
• Assignment in Safety ES during the conguration phase
• Setting on the DP interface using the pushbuttons and display
• Setting using the PROFIBUS service SET_SLAVE_ADD, e.g. in SIMATIC Manager: "Target
system" > "PROFIBUS" > "Assign PROFIBUS address"
① PC / PG with Safety ES using the device interface on the DP interface
② Manual setting on the DP interface using the pushbuttons and display
③ PC / PG with PROFIBUS interface
④ DP interface
⑤ Safety relay
Figure 6-17 Options for setting the DP address
The DP address can in principle be changed using all three access channels. The DP address last
written or set in the DP interface is the valid address.
Individual access paths for changing the DP address can also be disabled. This can be carried out
via the parameterization of the DP interface in Safety ES.
WARNING
Hazardous system state due to unauthorized access via PROFIBUS
Possible Death, Serious Injury, or Property Damage
Unauthorized access to the safety relay via PROFIBUS can enable conguration changes and
overriding of safety functions.
To prevent unauthorized access to the safety relay via the PROFIBUS network, assign a password
for accessing the device in Safety ES. If you operate several safety relays in one PROFIBUS
network, you must assign a separate password for each safety relay to prevent confusion when
accessing via PROFIBUS. In other words, the passwords must not be identical.
