Abstract: A method for multicore processor fault detection during execution of safety critical software applications in a multicore processor environment involves dedicating the complete resources of at least a part of at least one processor core to execution of diagnostics software application whilst dedicating remaining resources to execution of a safety-critical software application, thereby enabling parallel execution of the diagnostics software application and the safety-critical software application. There is also provided a controller for multicore processor fault detection during execution of safety critical software applications in a multicore processor environment. The controller includes a multicore processor environment. The controller may be part of a control system. The method may be provided as a computer program.

Abstract: A transmitting node in an industrial wireless network transmits a first number of bits to a receiving node, where at least one bit is partitioned into segments and each segment is transmitted at a different frequency according to a frequency transmission scheme. The receiving node receives the number of bits, determines the quality of each segment of a received bit, collects quality determinations of segments, forms a quality measure for each frequency through combining quality determinations of the corresponding frequency, compares each quality measure with a quality measure criterion, determines at least one frequency that does not fulfill the quality measure criterion and informs the transmitting node about frequencies for which the corresponding quality measures do not fulfill the quality measure criterion. The transmitting node receives the information and updates the frequency transmission scheme.

Each of the main TPU-part, safety TPU-part, main control part, and safety control part includes a processor for generating and/or handling the data. Each communication unit is connected to a network and forms a node in the network.

Abstract: A method is proposed for operating a system according to TDMA (Time Division Multiple Access) with a multiplicity of wireless sensors and/or actuators as nodes (S.1 . . . S.n) and a base station (BS), said system being installed in a machine or installation, such as industrial robots or an automated manufacturing or production unit, whereby cyclical TDMA data transmission blocks are transmitted and each TDMA data transmission block is composed of consecutive time slots. Each time slot is allocated to a specific node. The uplink signals (UL.1 . . . UL.n) can be transmitted from the different nodes (S.1 . . . S.n) to the base station (BS) simultaneously on two, three or more different frequencies (f1, f2, f3) whereas the. downlink signals (DL) are transmitted from the base station (BSA) to the different nodes (S.1 . . . S.n) on only one frequency, which differs from the uplink frequencies. The time slots and the different uplink frequencies of the different nodes are defined once and are thereafter retained.
