Abstract: A method for operating a multiple axis machine includes controlling drives of the machine with a machine control system and monitoring the machine with a fail-safe control system having first and second redundant channels. Each of the first and second channels receives first input target values and first input actual values from the machine control system, and compares first reference target values (based on the first input target values) with first reference actual values (based on the first input actual values). A fault reaction is triggered if there is a deviation between the compared values that exceeds a specified tolerance. The first input values comprise reference position values of a machine-fixed reference or time derivatives thereof, and the machine control system determines target and/or actual reference position values based on a transformation between reference position values of the machine-fixed reference and axial position values of the machine.

Abstract: A system for controlling an industrial robot includes an industrial robot and a control apparatus. The control apparatus includes a multi-core processor having at least one first processor core and at least one second processor core. An operating system, which is configured to be executed by the multi-core processor, is configured to assign hard real-time tasks to the at least one first processor core and assign other tasks to the at least one second processor core. The hard real-time tasks control at least a component of the industrial robot.

Abstract: For individual safety monitoring of a manipulator by a control device, a part of the control device is configured by the manufacturer and a part of the control device is configured by a user. The manufacturer-configured part ensures a basic safety functionality of the manipulator independent of a user configuration; and/or a safety device of a control device for individual safety monitoring of a manipulator communicates with a control device for individual safety monitoring of an additional manipulator of a manipulator arrangement for superordinate safety monitoring of the manipulator arrangement.

Abstract: The invention relates to a computer system (6) having a multicore processor (20) and an operating system, in particular a so-called ‘general-purpose’ operating system. The multicore processor (6) has at least one first processor core (21) and at least one second processor core (22). The operating system is configured to allocate real-time tasks, in particular hard real-time tasks, solely to the first processor core (21) and to allocate further tasks solely to the second processor core (22).

Abstract: The hard-wired non-maskable interrupt (10) of a conventional processor (7), i.e. NMI or IOCHCK, is used to bypass programed interrupts to obtain immediate, predictable access to the processor and avoid the long and uneven access times of programmed interrupts. The NMI interrupts are controlled by a programmable distributor (8). This allows the conventional computer system to operate on a real-time basis, since all the interrupts take the same time.
