PROFI-DCP

A simple Python library to send and receive messages with the Profinet Discovery and basic Configuration Protocol (DCP) protocol. It can send requests and parse the corresponding responses to identify devices over the network, get and set their parameters or reset them to factory settings. Documentation can be found here and in the examples directory.

This is a fork from pnio_dcp.
