摘要
In a special safety switch mechanism several processing units are arranged in pairs and form an original processing channel and a synchronously operated complementary processing channel which are operated dynamically and alternately in positive and negative logic, in successive processing steps, while using rectangular signal voltages of a given frequency at 180 DEG phase shift for the two logical values ZERO and ONE of the switching variables. During an operation, the signal anti-valency applied to the processing channels is continuously examined. In each processing channel, two-read-only memories are provided for storing fixed values in the form of original and complementary information which are alternately and in successive processing steps connected with the safety switch mechanism for information output.
