5.6 Setting the PROFIBUS address
Changing the PROFIBUS DP Address
1. Use the screwdriver to set the PROFIBUS DP address "0" by means of the DIP switch.
2. Switch the supply voltage of the ET 200iSP on and off at the Power Supply PS. The deletion
operation is finished when the BF LED flashes (0.5 Hz, duration approx. 10 s).
The ET 200iSP saves the parameters retentively in the Flash memory of the IM 152.
Therefore you should delete the retentive stored parameters during the initial
commissioning or after the modification of the system.
3. Now set the new PROFIBUS DP address by means of the DIP switch and again switch the
supply voltage on and off at the Power Supply PS.
Figure 5-16
Note
If you change the PROFIBUS DP address without previously erasing the retentive parameters
in the Flash memory, the ET 200iSP does not respond with either the new or to the old address
on the PROFIBUS DP.
