Abstract: A data transmission system comprising an Automotive Sensor Network System (ASNS) connected to a plurality of source locations via a common bus, wherein the ASNS is configured to ascertain the source from which the data-frames and first package checksum are received and based on the ascertainment of the source, appropriate decoding methods are used to calculate the ASNS location data-frame checksums and the ASNS location package checksums. A higher order redundancy check is done over a series of data-frames to detect errors in the reception caused by temporary high interference that may exist in the transmission path.

Abstract: A method transmits data packets on a data transmission link between two communication subscribers. The data packets respectively contain a check character which is calculated from the other data in the data packet. One communication subscriber uses the check character from the last data packet received by the other communication subscriber as start value for calculating the check character for a subsequent data packet which is to be sent to the other communication subscriber.

Abstract: Technologies pertaining to authenticating data output by sensors in an industrial environment are described herein. A sensor sentinel computing device receives time-series data from a sensor by way of a wireline connection. The sensor sentinel computing device generates a validation signal that is a function of the time-series signal. The sensor sentinel computing device then transmits the validation signal to a programmable logic controller in the industrial environment.

Abstract: A highly reliable industrial control system is produced using a network running a standard serial protocol. A safety protocol is embedded within the standard serial protocol by adding to special error detecting data redundant with the protocol of the standard serial network. In addition an overarching protocol involving timing of messages is imposed to provide the necessary level of reliability in the standard serial network. This approach allows the safety protocol to be used with a wide variety of commercially available serial communication standards without modification of the media or the specialized integrated circuits used for that communication. Safety protocol may be implemented in an additional level for integrated circuits or through firmware changes in programmable aspects of the industrial controller components.
