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)
