Dynamic IP address assignment
In those cases in which the PROFINET interface is not used for the IO communication, it is
possible to generate an IP address centrally using a DHCP (DHCP = Dynamic Host
Configuration Protocol) server. The following requirements must be satisfied to do this:
●
At least one DHCP server must be active.
●
The PG/PC and the SINAMICS devices must be connected to the same physical Ethernet
subnet.
Note
DHCP is not supported together with PROFINET. No cyclical connection is established for
an activated DHCP. It is therefore recommended that DHCP not be used within PROFINET
networks!
The DHCP address assignment can be set from the SIMATIC Manager or using SINAMICS
parameters.
Setting the DHCP address assignment with SIMATIC Manager (STEP 7)
1.
Call the "Target system > Edit Ethernet node" menu path in the SIMATIC Manager.
2.
Click the "Search" button in the "Ethernet nodes" area.
3.
Select the desired SINAMICS device.
You can now specify in the "Edit Ethernet nodes" configuration dialog that a dynamic IP
address will be generated via a DHCP server. The IP address can be identified in two
ways:
–
MAC address
–
Device name (name of station)
The "MAC address" option has the disadvantage that the MAC addresses are no longer
correct after a device has been replaced.
4.
Click the "Obtain the IP address from a DHCP server" option in the dialog to activate.
5.
Activate either the "MAC address" or the "Device name" option in the "Identified via" area.
6.
Click "Assign IP configuration".
The IP address is then taken from the DHCP server. The SINAMICS device uses the
associated setting after a POWER ON to obtain a new IP address from the DHCP server.
