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 decimal point.
The IP address is made up as follows:
● Address of the station (also called host or network node)
● 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. The IP address can be
assigned retentively via the STARTER function "Accessible nodes".
This function can also be performed with HW Config of STEP 7. Here, the function is called
"Edit Ethernet node."
Note
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.
Ethernet interface X127 is intended for commissioning and diagnostics.
Do not use this interface for other purposes and ensure that X127 is always accessible (e.g.
for service).
Note
Part of a company network
If the network is part of an existing Ethernet company network, obtain the information (IP
address) from your network administrator.
