IP address
The TCP/IP protocol is a prerequisite for establishing a connection and parameterization. To
allow a PROFINET device to be addressed as a node on Industrial Ethernet, this device also
requires an IP address that is unique within the network. The IP address is made up of 4
decimal numbers with a range of values from 0 through 255. The decimal numbers are
separated by a period. The IP address comprises:
● the address of the node/participant (also called host or network node)
● the address of the (sub) network.
IP address assignment
The IP addresses of IO devices can be assigned by the IO controller and always have the
same sub-network mask as the IO controller. In this case, the IP address is not stored
permanently. The IP address entry is lost after POWER ON/OFF.
If the IP address is to be stored in a non-volatile memory, the address must be assigned
using the Primary Setup Tool (PST) or STARTER.
This function can also be performed with HW Config of STEP 7. Here, the function is called
"Edit Ethernet node".
NOTICE
IP addresses of the onboard interfaces
It is not permissible that the IP address band of the Ethernet interface and the PROFINET
interface are the same. The factory setting of the IP address of the Ethernet interface X127
is 169.254.11.22; the subnet mask is 255.255.0.0.
Note
If the network is part of an existing Ethernet company network, obtain the information (IP
address) from your network administrator.
Device name (NameOfStation)
When it is shipped, an IO device does not have a device name. An IO device can only be
addressed by an IO controller, for example, for the transfer of project engineering data
(including the IP address) during startup or for user data exchange in cyclic operation, after it
has been assigned a device name with the IO supervisor.
NOTICE
The device name must be stored retentively using either the Primary Setup Tool (PST) or
with HW Config of STEP 7.
