Addresses

Definition: MAC address
Each PROFINET device is assigned a globally unique device identifier at the factory. This 6-
byte long device identifier is the MAC address. The MAC address consists of:
● 3 bytes manufacturer's ID and
● 3-byte device identification (consecutive number)
The MAC address is usually indicated on the front of the device.
For example: 08-00-06-6B-80-C0
IP address
To enable 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 periods. The IP address is made up of
● The address of the (sub-) network and
● The address of the node (generally called the host or network node)
IP address assignment
The TCP/IP protocol is required to establish a connection and assign parameters; this is the
reason that an IP address is required.
The IP addresses of IO devices can be assigned by the IO controller and always have the
same subnet screen as the IO controller. They can be assigned in an ascending sequence
starting from the IP address of the IO controller. The IP address can be changed manually if
necessary, and is saved in the volatile memory.
If the IP address is to be saved in the non-volatile memory, the address must be assigned
using the Primary Setup Tool (PST) or STARTER.
This can also be carried out using HWConfig in STEP 7, where the function is called "Edit
Ethernet node".
Note
If the network is part of an existing Ethernet company network, ask your network
administrator for the information you need (IP address, subnet screen, and any router that
may be in use.)
