    摘要: A safety control block interfaces to one or more devices utilizing one or more communication protocols wherein a network interface receives and/or transmits data directly from a network. A backplane interface receives and/or transmits data from a backplane. A backplane extension receives and/or transmits data from a backplane. A processing component receives data from at least one of the network interface, backplane interface and backplane extension and determines if the received data is related to safety or non-safety. A safety I/O circuitry receives safety data from the processing component; wherein the safety data is utilized to communicate to at least one control device.

    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: Methods and apparatus for redundancy in machine or process control systems provide redundant communication adapters located with the groups of I/O modules, so that if the first communication adapter faults or becomes unavailable, a second communication adapter will perform all of the necessary functions of the first adapter. The adapters are connected to a multiplexing module for communicating input data from the I/O modules to the communication adapters, for exchanging initialization data with the first communication adapter and the second communication adapter to initialize the redundant mode of operation and for monitoring communication of the first communication adapter and the second communication adapter on the network to start up the second adapter as the primary adapter for communicating both input data and output data with the I/O modules.
