B&R X20BC008T
Communication technology: OPC UA Field eXchange (FX) I/O configuration via OPC UA FX 400 µs minimum cycle time Integrated switch for daisy-chaining 2x 1 Gbit/s full-duplex mode OPC UA diagnostics and module diagnostics at runtime via OPC UA clients This bus controller provides OPC UA FX functions. This allows any OPC UA clients access to read or write data from I/O modules connected to the bus controller.
