Title
(EN) System and method for controlling bus-networked devices via an open field bus
Abstract
(EN)

A system for controlling bus-networked devices includes a gateway including a memory unit and having an interface to an open field bus. A power supply unit supplies primary power for the gateway and bus subscribers. An auxiliary power supply unit supplies auxiliary power for the bus subscribers independent of bus functionality. A pluggable connection cable is electrically connects the gateway to the bus subscribers and transmits the primary and the auxiliary power and control and/or status information between the gateway and the bus subscribers. An application bus networks the bus subscribers to each other and is operable by the connection cable. A bus controller writes a target bus configuration of the application bus and stores the target bus configuration in a non-volatile manner in the memory unit. The bus controller is also configured to overwrite the target bus configuration with a present, actual bus configuration.
