Abstract:
Monitoring and control device (38) for monitoring a technical system (10) with enhanced safety requirements that comprises at least one portable and/or mobile and/or immobile device a handling device arranged in a protective device, with at least one preferably central and/or decentralized control unit (36) as well as actuators (24-30; K1, K2) connected to the control unit for executing dangerous operations, whereby the monitoring and control device (38) is connected to sensors (20, 22) and/or actuators (24-30) and evaluated, processes and controls their status, the control unit (36) is connected to sensors (20, 22) and/or at least one of the actuators (24-30) and the monitoring and control device (38) via at least one data circuit, that the monitoring and control device (38) transmits at least one release signal to the control unit (36) in accordance with the status of the sensors (20, 22) and/or actuators (24-30) in order to enable at least one operation in the technical system (10), that the release signal triggers an operation, which is monitored by the monitoring and control device (38) by comparing the release signal with stored and/or specified execution and/or function and/or plausibility specifications or processes of movements, and that in case of an error at least one other signal is generated, which transfers the system into a safe conditioncharacterized in that microcontrollers (58, 60, 102, 120) are connected to each other via a connection (88) for mutual data exchange purposes that the actual status values transmitted by the drive controls (50) are declared with an identifier and that upon receipt of these identifiers an interrupt is triggered in each microcontroller (58, 60, 102, 120) of the monitoring and control device, and that the monitoring and control device is equipped with a time expectancy device for safety-related data and that each actual status value and/or value range is assigned at least one safety-related output and/or input (92, 94) of the monitoring and control device (38), with the outputs and/or inputs being connected to passive and/or active switching elements (96, 98).
