With the new DP/PN coupler, a simple and uncomplicated connection of PROFIBUS to PROFINET is possible. It allows data transfer between a PROFIBUS master and a PROFINET controller. The maximum size of the transmitted data is 244 bytes of input data and 244 bytes of output data. The DP/PN coupler is projected via a GSD file on the PROFIBUS side and a GSDML file on the PROFINET side. No additional configuration software is necessary.
