Assigning the PROFINET IO device name
For PROFINET IO, the IP address parameters are assigned via DCPl (Discovery and
Configuration Protocol). DCP uses the so-called device name for this purpose.
The device name uniquely identifies a PROFINET IO node in the network. It is given
to the PROFINET IO controller when the node is configured and also set using the
configuration software on the PROFINET IO device.
During startup, the IO controller identifies the device based on the device name and
transfers the corresponding IP address parameters. The settings directly at the slave
are thus no longer necessary.
The following example with the TIA Portal configuration software describes the gen-
eral procedure:
ü
Make sure that the "Device view" tab of the TIA Portal is open.
1. Right-click the I/O system and select the menu item "Assign device names" in the
context menu.
