Embodiment Construction

[0054]figure 1 A safety system 1 for safe operation for machine 2 is shown schematically shows. Danger, especially for people's hazards may come from machine 2. In respectively, the dangerous area 3 surrounding the machine 2 is protected by the column 4. Two protective doors 5 are provided in the fence 4, and people can obtain the inlet of the hazardous area 3 through the protective door.

[0055]Set the safety control device 6 as the main component of the safety system 1, the safety control device controls the operation of the machine 2. Typically, the safety switch is provided as another component of the security system 1, and the protective door 5 is monitored by the safety switch. Safety control device 6 controls the operation of the machine 2, in particular based on a signal generated by the security switch.

Abstract

A control device (7) for a system controlled by a controller with an evaluation unit (9) and at least one acquisition unit (17a, 17b) that is connected to the evaluation unit (9). Depending on input values that are input in the acquisition unit (17a, 17b), an operating mode selection can be performed and / or an access authorization can be granted. Output values generated in this manner can be output to the controller via an output stage (8).

Description

Technical field[0001]The invention relates to a control device for a system controlled by means of a control device.[0002]Such systems typically constitute safety systems that are used in the field of machine safety.Background technique[0003]This type of safety system generally includes a control system that controls a machine, where the term "machine" also includes facilities and the like. The danger to people within the danger zone may come from the machine.[0004]Monitoring the hazardous area is taken as a safety measure, in which the machine has a safety control device as a control system for checking and monitoring safety-related functions.[0005]For example, the hazardous area of ​​the machine is protected with protective covers and fences. Here, the protective gate or gate is located in the fence. Here, the monitoring is carried out so that only when there is no danger from the machine, the person can reach the danger zone through the protective door.[0006]An entrance system co...
