摘要： A high reliability network provides for measurements of network delays through pairs of transmissions of local clock values used in a first message to deduce clock value offsets and in a second message to reveal network delays.

摘要： A system serializes control signals within a safety control architecture wherein a safety serial interface at least one of receives and transmits signals from one or more processing components. A serialization component receives and serializes at least one data packet from the safety serial interface to control at least one of an input and an output associated with the safety control architecture. A safety related test circuit verifies input signals associated with the serialization component are not internally falsifying the state of the input signals. A heartbeat watchdog component verifies a true heartbeat bit in the at least one data packet is opposite a complement heartbeat bit in the at least one data packet within a predetermined time interval and shuts off power to at least one of an output and an input if such a condition is not met.

摘要： A bridge usable in a highly reliable industrial control system provides an interface between a producer module transmitting redundant messages in accordance with a communication protocol and a consumer module receiving the messages in accordance with a different communication protocol. The bridge includes a first network interface receiving two messages from the producer, a microprocessor capable of converting the messages from the producer communication protocol to consumer communication protocol, and a second network interface transmitting the messages to the consumer. One of the messages is reversible altered with respect to the other message. The altered message is uninverted in the consumer module, and compared to the other message to ensure that no transmission errors have occurred.

摘要： A highly reliable industrial control system provides for the processing of redundant control signals on as little as a single serial network without overloading the network by preprocessing input signals for coincidence and sending only the coincidence signal either periodically or on a change of state. Further compression of sent data is realized by extracting a reduced subset of transmission states from the input signals and transmitting only the transmission states.

摘要： An industrial control system uses a number of autonomous control units, each associated with one piece of equipment in an industrial process. The autonomous control units include data indicating not only their constraints of operation but also reflecting the constraints of operation of machines to which they are attached and with which they share common operating parameters. An autonomous controller associated with a machine having operating parameters in common with another machine adopts the intersection of the ranges of the machine constraint of the two machines. Machine constraints are preserved to the extent possible as ranges so as to permit flexibility in selecting and seeking goals by the individual autonomous control units.
