DCP


DCP – Discovery and Configuration Protocol

PROFINET DCP is part of the protocol suite and stands for “Discovery and basic Configuration Protocol”. It is used by the engineering tool and controller to discover devices, identify device information, and configure device settings such as PROFINET device name and IP address on a PROFINET network.
