6.8.2.3 Addresses

Definition: MAC address

Each PROFINET device is assigned a worldwide unique device identifier in the factory. This

6-byte long device identifier is the MAC address. The MAC address is divided up as follows:

● 3 bytes manufacturer's ID and

● 3 bytes device identifier (consecutive number).

The MAC address is usually indicated on the front of the device.

e.g.: 08-00-06-6B-80-C0

IP address

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 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 a prerequisite for establishing a connection and parameterization.

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 sub-network mask as the IO controller. The can be consecutively assigned from the IP

address of the IO controller. The IP address can be changed manually, if necessary - and is

saved in a volatile fashion.

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 can also be carried out in HWConfig in STEP 7, where the function is called "Edit

Ethernet node".

Note

If the network is part of an existing Ethernet company network, obtain the information from

your network administrator (IP address, sub-network mask and a router that is possibly being

used.)

Device name

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.
