Abstract: A method and system for interacting with data frames passing through a module connected to an industrial network is disclosed. Each module includes an aggregation unit located on the network interface above the physical layer. To transmit data, the aggregation unit reads a header from a dynamic data packet to determine if the module is a participant module for the packet. If so, the aggregation unit inserts data from the module into the data packet and transmits the packet to another module. To receive data, the aggregation unit reads a header from the data packet to determine whether the data packet includes data for the module. If so, the aggregation unit reads the data and passes the data packet to another module. If the aggregation unit determines that a data packet is not intended for the module, the data packet is passed to another module with no further interaction.

Abstract: A method of transmitting high speed serial data with reduced levels of radiated emissions is disclosed. A transmitting device scrambles data utilizing a pseudo-random number sequence generator. Scrambling the data eliminates transmission of repeated data sequences. The transmitting device similarly scrambles idle pairs of data between data transmissions to eliminate an additional source of repeated data sequences. The scrambled and encoded data is transmitted to a receiving device. The receiving device also includes a pseudo-random number sequence generator. Synchronization of the two pseudo-random number sequence generators occurs by utilizing control characters of the data frame being transmitted. Each of the pseudo-random number sequence generators is configured to generate the same sequence of numbers and is initialized to start with a first number in the sequence of numbers corresponding to the first byte of data being transmitted or received.

Abstract: A system with multiple processing domains sharing a memory resource accessed via a shared memory controller detects a memory error. As data is written to the shared memory resource, each processing domain generates a diagnostic code as a function of the data, the memory address for the data, and of a unique identifier corresponding to the processing domain. The diagnostic code is stored with the data for verification when the data is read back. As the data is read back, the processing domain separates the diagnostic code from the data being read and generates another diagnostic code in the same manner as the original diagnostic code. The other diagnostic code is compared to the initial diagnostic code. If both diagnostic codes are the same, the processing domain can be confident that the data read from the shared memory resource is the same as the data that was originally written.

Abstract: A system for communicating between redundant devices balances the desired attributes of a high availability (HA) control system and a safety control system. The system includes concurrent connections as a fault tolerant mechanism for industrial protocol connections at the transport layer. The concurrent connections establish multiple paths for redundancy from a data producer to a data consumer. Concurrent connections increase availability of the HA control and safety instrumented systems. More specifically, concurrent connections and architectural redundancies eliminate a single point of failure within the control system and further reduce safety connection timeouts during fault detection and/or recovery. Concurrent connections may be used to keep a HA system operational or to provide detection of a failure in a safety system. The industrial control network may be configured to function as a HA control system, as a safety control system, or with certain degrees of both HA and safety-related operation.
