Machine control system for a machine carrying out dangerous actions, such as a press, comprising at least one disconnecting path

The controller has a disconnecting path (ABSCH) for disconnecting an output of the controller based on the change in a state at the inputs. The disconnecting path comprises of logic circuits (LSA, LSB) for the time-critical control commands independent of the cyclic time of the controller. The disco...

Zusammenfassung:The controller has a disconnecting path (ABSCH) for disconnecting an output of the controller based on the change in a state at the inputs. The disconnecting path comprises of logic circuits (LSA, LSB) for the time-critical control commands independent of the cyclic time of the controller. The disconnecting path has a test circuit with which the inputs of the path are definitely controlled in an "open" period.
