Gateway PROFIBUS-DP to Serial

    • Cost optimized, compact design
    • Serial Master or Slave to PROFIBUS-DP Slave
    • RS232/422/485 to PROFIBUS-DP
    • Can be a Master to one Profibus slave
    • FDT/DTM Configuration Tool SYCON.net included
    • Ethernet Service Port
    • Non-isolated serial interface, unit must be correctly grounded to avoid data corruption.
    • For isolated unit use NT100



The netTAP uses the netX network controller to provide a low-cost and easy solution for different protocol conversions. The different interfaces are combined in a compact housing. Firmware is loaded via Ethernet to suit the required protocol.
