7.5 Integrating the Modular Safety System 3RK3 in DP master systems
7.5.1 Setting and changing the DP address
The DP interface offers three ways of setting and changing the DP address:
● Assignment in MSS ES during the configuration phase
● Setting on the DP interface using the pushbuttons and display
● Setting via HW Config (STEP 7 (PROFIBUS service SET_SLAVE_ADD))

Figure 7-4 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 MSS ES.
Setting and disabling the DP address in MSS ES
In MSS ES, the DP address is set in the object properties of the DP interface module during
configuration (see also
Properties of interface modules (Page 132)). When downloading the
entire configuration, the DP address (station address) is transferred to the device.
In MSS ES, individual methods of changing the DP address can also be disabled. The
following protection levels are available for this purpose:
