The DP/DP coupler interlinks two PROFIBUS-DP networks and permits data transmission between the masters and the two DP networks. The maximum size of the transmitted data is 244 bytes of input data and 244 bytes of output data. The DP/DP coupler is configured in the S7 software or by means of a GSD file.




  • Up to 244 Bytes of input data and 244 Bytes of output data can be exchanged between two PROFIBUS networks
  • Dual-redundant power supply
  • Electrical isolation between the PROFIBUS networks
  • PROFIBUS addresses can be set by DIL switch or software
  • PROFIBUS-DP up to 12 Mbps
