Gateways with OPC UA from Bihl+Wiedemann

Using OPC UA in Bihl+Wiedemann Gateways you can release and then access your machine data as desired. The following data can be called up over your company network (examples):

  • I/O map for both ASi circuits and monitors
  • Device diagnostics
  • Fieldbus bits
  • Slave addressing
  • Safety diagnostics + Safe Link diagnostics
  • ASi EC flags and ASi fault detector
  • Safety at Work Monitor (max. 64 release circuits)
