Abstract
Device () for controlling and/or monitoring external technical processes, in particular a device for use in connection with safety-related controls. The device includes an input functionality, an output functionality and a processing functionality that can be connected with at least one higher-level unit () for transfer of process-influencing and/or process-monitoring signals by way of a bus system () to and/or from actuators () and/or sensors () connected to the device. A guaranteed response time over the bus system () is determined on one hand by the cycle time of the higher-level unit () and on the other by the signal cycle time over the bus system () itself. In order to provide a shorter response time than this in appropriate circumstances, the device () uses the processing functionality thereof to execute logical links internally. The results are available for process control and/or process monitoring after a time interval that is shorter than the guaranteed response time of the higher-level unit () over bus ().
