Abstract

A control system configured to control safety-critical and non-safety-critical processes and/or plant components includes: a non-safety controller module, at least one safety controller module, and at least one condition monitoring module. The non-safety controller module is configured to control the non-safety-critical processes and/or the non-safety-critical plant components. The at least one safety controller module is configured to control the safety-critical processes and/or the safety-critical plant components. The at least one condition monitoring module is configured to perform fail-safe condition monitoring and to collect monitoring data. The non-safety controller module is configured to receive the collected monitoring data from the condition monitoring module and to pass the collected monitoring data to the safety controller module. The safety-controller module is configured to evaluate the monitoring data based on safety conditions.
