7.5 Integrating the Modular Safety System 3RK3 in DP master systems
● Can be changed without restriction
The DP address can be changed by downloading the configuration to the device (data
set) by means of MSS ES, on the DP interface itself using the pushbuttons and display,
and via the PROFIBUS service SET_SLAVE_ADD.
● Can only be changed by means of MSS ES or setting element on the device
The DP address can only be changed by means of MSS ES and on the device itself
using the pushbuttons and display.
The DP address cannot be changed by means of SET_SLAVE_ADD.
● Can only be changed via the data set
The DP address can only be changed with MSS ES.
The "DP-Adr" menu command is still available, but the DP address cannot be changed
and is rejected with the message "Lock".
Setting the DP address on the DP interface
The DP address can be set and changed on the DP interface itself using the pushbuttons
and display. The DP interface displays the current DP address.
Setting via HW Config (STEP 7)
In HW Config, you can assign a new DP address using the menu command "Target system"
> "PROFIBUS" > "PROFIBUS address" (PROFIBUS service SET_SLAVE_ADD). If the
central unit does not yet have a configuration, the DP interface displays the default address
126.
Further changes to the DP address can be blocked via the PROFIBUS service
SET_SLAVE_ADD. This block can only be revoked as follows:
● By restoring the factory settings of the central unit (deleting the configuration).
● By downloading the new configuration to the device.
7.5.2

DP interface

The display has two operating statuses:
● Standard mode with status display
In standard mode, different status messages are output. To scroll through the messages,
choose "MODE".
With error messages, the first line flashes and displays the type of error. If more than one
error type is present, the cursor appears in this line as a chaser.
The second line may contain a parameter providing information about the type of error. If
more than one error type is present, the cursor appears in this line as a chaser.
This indicates that you can call up additional messages/parameters when you choose
"MODE".
If more than one error type is present and these have more than one parameter, you can
scroll through the parameters by choosing "MODE" (cursor in the second line). The next
error type is then displayed (cursor in the first line). The sequence of messages is defined
by a prioritization indicator. Parameters are sorted in ascending order within an error
type.
An error that has been rectified is immediately deleted from the display (you do not need
to refresh the screen).
