Address setting in PROFINET
In IP-based communication, the field devices are addressed by means of an IP address.
PROFINET uses the Discovery and Configuration Protocol (DCP) for IP assignment.
When delivered, each field device has, among other things, a MAC address. This information is
sufficient to give the respective field device a unique name.
The address is assigned in two steps:
n
Assignment of a unique plant specific name to the respective field device.
n
Assignment of the IP address from the IO-Controller before the system start-up based on the
plant-specific (unique) name.
