The invention relates to a control and regulating system of an oxygen-reducing system, comprising at least one inert gas generator (), at least one oxygen concentration sensor (), at least one actuator () for releasing inert gas, wherein the control and regulating system comprises a plurality of signal-connected controller modules (), each configured or configurable so as to enable the execution of one or more regulating functions, wherein the regulating functions are decentrally distributed to at least two signal-connected controller modules ().

Open-loop and closed-loop control system of a deoxygenation plant

A control and monitoring module is provided for activating an actuator assigned to the control and monitoring module and for monitoring a signal line and/or a power supply line connected to the control and monitoring module and/or to the actuator. The control and monitoring module is configured to detect a fault in the signal line and/or the power supply line, if, during a simulation executed by a testing device, an actual voltage at the control and monitoring module and/or the actuator exceeds a specified upper voltage threshold value or drops below a specified lower voltage threshold value. A system including the control and monitoring module and a method for operating a control and monitoring module are also provided.

Control and monitoring module

The invention relates to a bus system () comprising a control unit () and at least one bus node (). The control unit () is allocated at least two data communication interfaces () which are respectively designed to transmit and receive data. The at least one bus node () comprises a bus coupler having at least two data communication interfaces () respectively designed to transmit and receive data. The control unit () and the at least one bus node () are respectively connected together via their data communication interfaces and corresponding two-point connections () to form a ring topology. The bus coupler of the at least one bus node is designed to directly and without delay transmit, and thus forward, data received at one of its at least two communication interfaces via its other data communication interface.
