Abstract: An apparatus for controlling an automated installation has a first controller and a second controller that are connected to one another via a communication network. The first and second controllers each have a local clock and execute control tasks. The first and second controllers each further have a synchronization service that is used to synchronize the respective local clocks to a common reference clock. A timer repeatedly sends a trigger message to the first and second controllers. Each of the two controllers, on receiving the trigger message, determines a local time. The controllers interchange the respective local time and each compute a difference between their own local time and the local time obtained from the other controller. On the basis of the difference, each of the two controllers controls a local actuator.

Abstract: A process data transmitter transmits process data at defined recurring time intervals as a serial transmit data stream including data symbols at a defined symbol rate. A process data receiver samples the serial transmit data stream at a sampling rate which is higher than the symbol rate by a defined factor to thereby generate a serial receiver data stream having a plurality of sampling values per data symbol. The process data receiver subdivides the serial receiver data stream into data packets, each of which has a defined first number of sampling values. The process data receiver selects a defined second number of sampling values from the respective data packets. The second number is smaller than the first number by the defined factor and the sampling values selected from each data packet are equidistant from one another. The process data receiver processes the selected sampling values as received process data.

Abstract: A method and device for safeguarding a hazardous working area includes a camera system for generating successive 3-D images of the working area, and an evaluation unit comprising a fail-safe foreign object detector, a classifier, a person tracker and a comparator. The foreign object detector generates a first signal comprising a first item of position information, representative of the position of a foreign object in the protection zone.

If the position of the foreign object according to the first item of position information and the position of the identified person are different from one another, a control signal for stopping the machine is generated.
