    • Enhanced diagnostics capability, such as duplicate address detection, integrated earth fault and EMC monitor

    Safe Communication

    Safe Link either over diagnostic or fieldbus interface


    For applications that work with traditional fieldbuses, the exchange of safe information runs over the Ethernet diagnostics interface of the ASi Gateways with integrated safety monitor.

    When an industrial Ethernet derivative is being used as the fieldbus, the ASi networks can when desired be coupled over the fieldbus interface of the Gateways and communication takes place over the already existing Ethernet network.
