Abstract: The present disclosure relates to an I/O station, connected with a plurality of network devices in an automation system. The station comprises a plurality of I/O modules, each I/O module providing one or more I/O channels connecting respective one or more field device(s). The station also comprises an I/O network interface for forwarding data between the modules and the network devices via a network. Each of the channels connecting a respective field device is communicatively connected to at least one of the network devices via the network. The station further comprises a non-volatile storage storing configuration data for the station.
