Changing the Node Address of S7 Stations
To change the preset node address, proceed as follows for S7 stations:
1. Configure the station; set the node address of the connected module (for
example, a CPU) in the "General" tab ("Properties" button under "Interface").
2. Switch the module to STOP and connect your programming device to the
interface on the module via a connecting cable.
3. Determine the preset node address of the connected module (using, for
example, the menu command PLC > Display Accessible Nodes in the
SIMATIC Manager).
4. Download the configuration with the new node address to the programmable
controller (that is, to the connected module):
- In the station view (Configuring Hardware) using the menu command PLC
> Download
- In the network view (NetPro) select the station you want to download and
select the menu command PLC > Download > In The Current Project
>Selected Stations. Enter the "old" (still valid) preset address.
