Product description:

DP/PN Coupler

With the 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 configured using a GSD file on the PROFIBUS side and a GSDML file on the PROFINET side.

No additional configuration software is necessary!



  • Very compact design for DIN rail mounting
  • Exchange of up to 244 bytes I/O data
  • Redundant power supply
  • Galvanic separation of the networks
  • No influencing of the opposite side in the event of bus system failure
  • Setting of the PROFIBUS addresses using DIP switches or software
  • Configuration only with GSD/GSDML file
  • No additional software necessary!
