Configuring the IP address
Alternative ways of assigning the address parameters
You can decide the route and the method with which the IP address of the local interface is
obtained and assigned.
●
Set IP address in the project
This is the default setting. You specify the IP address when the device is networked. The
IP address CP is therefore fixed. With this option, you need to configure the
communication connections.
The configuration can be achieved in the following ways:
–
PST, see section Assign the address and network parameters with the Primary Setup
Tool (PST) (Page 48).
As an alternative to STEP 7, you can use the PST to assign the address and
PROFINET parameters.
–
STEP 7 V5, see section Configuration with STEP 7 V5.5 (Page 51).
–
STEP 7 Basic / Professional, see section Configuration with STEP 7 Basic /
Professional (Page 57).
●
Obtain IP address from a DHCP server
This is an alternative method if the LINK is operated in standard mode as a gateway.
With this, you specify that the IP address is obtained from a DHCP server when the
device starts up. To do this, the MAC address of the interface or the client ID that can be
entered in the configuration or the PROFINET device name is transferred to the DHCP
server.
You will find further information in the configuration manual for S7 CPs /3/ (Page 90).
